From Idea to $650M Exit: Lessons in Building AI Startups

What we're going to talk about today is how my company uh built an AI app that was so good we're able to bring it to an exit for $650 million and how you can do that too. All right, so really we're talking about three big ideas today. The first is what ideas to pick. How do you decide what to pursue? Second is how you actually build it. And third, and honestly often overlooked, is how you take that thing that you built and market and sell it successfully in the market. Before we dive into this, a little bit about me so you know who's talking to you. I grew up a coder. Uh I've been building stuff since as long as I can remember. It's probably the same as basically everybody here. Bit of a side quest for me, but I fell in love with law and policy and I became a lawyer. And I had a pretty conventional though brief legal career. uh law school, clerkship, you know, big law firm, etc. I think like anybody who builds stuff and then goes to one of these old professions like law or accounting or finance or whatever, the first thing you find out is I cannot believe that they were doing it this way. And so I immediately left that and founded a company called Caseex in 2013 when I think uh a lot of you were about turning eight. And maybe as a side note, that's about how long it takes sometimes for these companies to be successful. So, I know you're, you know, 18, 19, 20, 21, 22, whatever old right now. Be ready to sign up for one of the most amazing adventures of your life when you start a startup, but it takes time. At KStex, we've been focused for, you know, the vast majority of our experience on a deep conviction that AI when applied to law can make a huge difference. And by the way, it wasn't even called AI when we started focusing on it. It was called natural language processing, maybe machine learning. But one of our AI researchers who is here today uh Javeed saw woo saw an early application um as soon as the BERT paper came out attention all you need etc. this like seven years ago of how AI technology could apply to uh making lawyers lives better for example making search a lot better because we were so focused on large language models and were researching deeply in this space we got really early access to GPT4 like summer 2022 we were like $20 million in revenue we were doing great I had like 100 people and we stopped everything that we were doing and said we're going to build something totally new based on this new technology and that became a product called co-consel which was the first ever and I think still the best AI assistant for lawyers for reasons I'll go into the rest of this talk we were acquired by Thompson Reuters uh not about two years ago for $650 million in cash by the way that feels like a big number but I think for a lot of folks in this room you're going to look back at this talk and be like I can't believe that was a big number back then you guys are going to be able to build things that are so much more valuable I I really believe that and I think that's because the what AI is going to unlock for all of you is the ability to build amazing stuff in this for this world. So, okay, how do you pick an idea? something people want. And the reason they had that saying is because it's genuinely difficult to know what people want, especially in like the old world of binning software. You kind of like have to build something, get it in users hands, and try and fail a lot of different times. And you just hope that it's something that people actually want to use. So that's why the saying for Y Comier is make something people want. I actually think it just got a lot easier because what do people want? Well, what do people want? For example, things they're paying for right now. People are currently paying people to do tasks, right? In this case, it's a bunch of very unhappy like customer support people or something like that. But we already know what people want because they're paying people to do it. This includes a lot of work like customer support or insurance adjusters or parallegals or in you know things you do in your personal life like personal trainers or executive assistants or whatever. That is what people want. And so the the problem of choosing what people want just got a lot easier because now you just have to look what are people paying other people to do uh for a lot of those problems either you know traditional AI like LLMs can solve many of the problems that people work on right now and if not that then robotics can solve a lot of things that people are working on in the physical world and what I think you're going to see as you decide what you're going to build you you first pick an area to target it really kind of falls under three different categories one is like assistance where say a professional needs help accomplishing a task. That's what we built at co-consel. Lawyers need a lot of help reading a lot of documents, doing research, reviewing contracts, marking them up, making red lines, sending them to opposing council. So that's one big category is assisting people doing their work. The second big category is just replacing the work altogether. People currently hire lawyers. What if we just became a law firm powered by AI? people currently hire accountants and find financial experts and physical therapists and and and you know people to fold your laundry whatever it may be right you can just replace that task using AI and finally the third category is you can do uh things that were previously unthinkable right like for example at law firms they would have hundreds of millions of documents and they would never think in a million years I should have people read over every single document and categorize it in certain ways and summarize it and index it, etc. It just would be insane, right? It cost them millions and millions and millions of dollars. But now that AI is here, you can have thousands of instances of Gemini 2.0, Flash, or whatever, read over every document. The previously unthinkable is now thinkable. These are basically the three categories um of ideas to choose. And what I think is incredible about this is the amount of money to be made with these new kind of categories each has gone way up. It used to be that what's called the total addressable market, which is basically how much money you can make from your product was the number of like professionals, for example, number of seats you can sell times the dollars like $20 per month or whatever, right? And by the way, a lot of many billion dollar companies are built selling seats to x number of professionals. But today, the actual amount of money that we already know people and companies are willing to spend is the combined salaries of all the people they're currently paying to do the job. And that number is like a thousandx bigger. You pay $20 a month to solve a problem. For example, you know, pay a typical SAS kind of subscription, but you might pay five or 10 or even $20,000 a month to certain professionals to solve problems for you. So the amount of money that you can make with your new applications with AI has gone up by a factor of 10, 100, or even a thousand compared to what it used to be. I want to take a quick moment because it might sound like pretty dystopian like we're talking about taking all these salaries and these these become, you know, your addressable market. I think it's kind of the opposite. I think it's beautiful. I think the f the future is beautiful for two reasons. The first is that you're going to unlock a future when you replace or substantially assist certain jobs. Like people used to Sam Alman wrote about this in a recent essay. People used to have a job called lamp lighters where we didn't have like you know electricity and lights. So people go around with a like matchick or like you know lighting all the lamps at night on and then turning them off at night by putting out the candles, right? That's what things used to be. And we couldn't even imagine the kind of stuff we're doing now because uh that's what we were stuck doing in the past. So you going to unlock a future that we can't even imagine today when we you know move past the roles that we're currently doing right now. It'll feel antiquated 10 or 15 or 100 years from now to do the kind of things we're doing today because you're going to help us move past that. But as importantly, what I think some people don't think about with this stuff, which I think is very true, is you're going to democratize access to things that were used to be really, really hard or very expensive. In the field we worked in in law, over 85% of people who are low income don't get access to legal services. It takes way too long and it's way too expensive working with human lawyers, right? But if you could help make lawyers 100x faster and 10x cheaper or you know frankly just provide those services yourself as a new law firm powered by AI then all of a sudden saying where where lawyers have to turn away clients because they did not have enough money you can now say yes and that applies everywhere everybody should get the world's best financial assistant everyone in the world should get the best executive or personal assistant everyone in the world you know can already have the best coding assistant in tools like curs cursor and wind surf etc right I do think that despite the fact that I'm telling you how to pick an idea is you should potentially replace jobs, I think you're going to do something really amazing for the vast majority of consumers and enterprises uh by unlocking a better future and by democratizing access to things that used to be only for the value very wealthy. Okay, so that's that's how to pick an idea, pick a job, replace, assist or do the unthinkable um those previously unthinkable and build a better future. But how do you actually build this stuff? I'm going to give you a quick outline of how we built it. What's kind of nuts to me is everything I'm going to say right now may sound very simple and common sensical and maybe even obvious, but the craziest is nobody's doing it. Like, nobody's picking ideas the way that I recommended in terms of picking job categories. There's very very few companies out there doing that. And even fewer companies are doing what I hope will look like pretty obvious and simple things to building um reliable AI. I put it reliable and underscore for what it's worth because that's going to be the key for for many circumstances in terms of getting from a cool demo as Andrew was saying earlier today something that actually works in practice. Here's like four quick points about how to actually build this thing. The first is think about like making an AI assistant or an AI replacement for say a profession. Ask yourself like what do people actually do? What does a professional in this field actually do? What does a personal trainer or fitness coach do if that's the app you're deciding to build? What does a financial assistant do or financial analyst do? And be like super specific. I'm going to say this a few times, but it is really helpful to actually know this answer, not like make it up. It was helpful for us that that I was a lawyer, my co-founders were lawyers, 30 to 40% of my company, even the coders were lawyers because we actually lived it. That may not be the case for you. Just go be like an undercover agent somewhere. Really learn what happens at these companies, right? What do these people do? Other way to do it, by the way, is you might be the tech talent and you might find yourself a co-founder who's a has some deep expertise in a field. But whatever way you get there, you know, find out what what are the specific things that people do that you can assist or replace. And then ask yourself this question. How would the best person in that field do this if they had like unlimited time and unlimited resources like a thousand AIs that can all work in, you know, simultaneously to accomplish this task, right? How would the best person do this and work backwards from there, right? What are the actual steps that somebody might take to accomplish a task? For just give you an example from our legal field, we did a version of deep research two and a half years ago. uh as soon as we got access to TPD4, it was like the first thing that we did and we asked like what was the what was the best lawyer going to do if given this research question. It wasn't like just generally research like what does that even mean? They broke it down to steps. Okay, first you know they get a request for this research project and they say okay well I need to understand what this really means. They might ask clarifying questions quite like deep research today if you've used it. And then they might make a research plan. They they might execute dozens of searches might that might bring back hundreds of different results. They'll read every single one of them very carefully. Kick out the stuff that's not relevant because search results are sometimes have irrelevant stuff. Bring in the stuff that is relevant. Make notes about what they're seeing, right? Why is this relevant? Why is this not relevant? Where does this fit into my answer? And then based on all of that, put together, put it all together in an essay. and then maybe even have a step at the end where you check the essay to make sure it's accurate and reli you know actually refers to the right resources um etc etc etc. These are the kind of steps that a real professional might do when doing research. So write them down. Now you turn to code. Most of these steps for the kinds of things you'll be doing end up being prompts. One or many prompts, right? One prompt might be read the legal opinion and decide on a scale of zero to seven, how relevant is it to the question that's being asked. One prompt might be given all these notes I've taken in all the cases I've read so far, write the essay. One prompt might be like, here's a here's a footnote in the essay, here's the original resource. Is this thing, you know, accurately cited or not? The reason why that many of them are prompts is because they're the kinds of things that would once require human level intelligence, but now you're injecting it into like a software application. So now you need to, you know, do do the work of turning it into a great prompt. I'll talk about in one second to actually do that human level intelligence. By the way, if you can get away with it not being a prompt, if it's like deterministic or it's like a math calculation or something like that, that's better. prompts are slow and expensive. Tokens are still expensive. So when you're breaking down these steps, some of these things might just be good old software engineering, right? Do that when you can. And then here you make a decision when you find out how the best person would approach this. If it's a pretty deterministic like every single time they always do this task, they always follow the same five steps. Simple. Make it a workflow, right? It's actually the easiest outcome for you. And to be honest, a lot of the stuff that we built while building code council was exactly like this. Every time you do this task, you're basically going to take the same six or seven steps. And you don't need to have frankly like lang chain or whatever. Just Python code. This function then the output of this function goes in this function output of this function to this function. Boom. You're done. Right? Simple. Sometimes it's not so simple. Sometimes how expert would approach the problem really depends on the circumstances. Maybe they need to make a very different kind of research plan, pull from different resources, run different kinds of searches, read different kinds of documents, whatever it may be that you're doing, right? That's how you get to something that's a little bit more agentic. That's harder to make sure it's good. But maybe what you have to do, right? Underscore this again in doing all of this, having some form of domain expertise, somebody who knows what they're talking about here, which by the way, you can also acquire just by talking to a lot of people. There lots of different ways to get here, but don't do it. Don't don't fly blind. Don't assume this is the way that all government employees in this field do X really know. Okay. So that's the basic way you can build these AI capabilities that start to round out and that's it right simple. The hard part frankly isn't building it. The hard part is getting it right. Like how do you know the research was done well? How you know it read the document right? How do you know it edited you know it did the insurance adjustment correctly? How do you know it made a correct prediction about whether to buy or sell a sock or whatever it is that you're doing? This is where evaluations play a very very very large part. And this is the thing that I see most people not doing because they build like demo level stuff that frankly is like 60 to 70% accurate. And if we're being honest, you can probably raise a pretty good round of capital by showing your cool demo to uh VC partners. And you can even possibly sign on your first few customers with the cool demo as a pilot program, right? But then it doesn't work in practice. And so all that excitement and VC capital raised and pilot program excitement, etc. uh falls apart if you can't make something that actually works in practice. And making something that works in practice is is really hard because uh LLMs like people, you know, you don't have your coffee that morning, uh you wake up on the wrong side of the bed, it might just output the wrong stuff for prompts. I'm sure you've all seen this before. Even if you just use chat tpt, you sometimes probably been blown away with its brilliance at times and other times shocked by how incredibly wrong it was about code or you know some informationational lookup or just hallucinating when George Washington's birthday was or whatever it is right so so how do you deal with that I'll tell you how we dealt with it um this is not the whole answer but a big part is evaluations next batch is now taking applications got a startup in you apply at y combinator.com/apply by it's never too early and filling out the app will level up your idea. Okay, back to the video. >> This all begins again from domain expertise which is like what does good look like? What does it mean to do this task super super well? Um if you're doing research, what is the you know for for X given question, what is the right answer? What must the what must the right answer include for X document? And you're asking a question that's a document. What must it pull out of that document. What pages should I find the information? What does good look like? This is true of the overall task like complete this research for me, but also each microtask necessary to complete the overall task like which which search queries are good search queries versus bad search queries. Here again, not sounding a broken record, but it's good to know what like actually prof actual professionals would say about this, right? So, what does good look like? And then those become your evals. My favorite thing to do when I'm writing evals for things that are like, you know, when when possible is to turn into like a very objectively gradable answer. For example, uh have the AI just output true or false or a number between zero and seven or whatever because then it's really easy to evalu. That's how relevant it is. It's not a seven, not a five, it's a six. And if you have that then you can set up an eval framework I like prompt fu I don't know if you guys use that it's like open source runs on on your command line there are many frameworks out there that you can use to you know put together the these evaluations doesn't really matter at the end of the day it's like for this input and this prompt the answer should be six make like a dozen try to match what your customers are actually going to throw at your program right make a dozen and then try to get it perfect on a dozen, then get to 50, then get to 100, and keep on tweaking the prompt until um it actually passes all the tests you keep on throwing at it. If you're doing really good about this, have a hold out set and don't, you know, look at those while you're while you're writing your prompts. Make sure it also works on those. You're not just just fine-tuning the prompt just for your evals, right? What you'll find without any I use the word fine tuning without any like technical fine-tuning you can go so far with just prompting if you're being really careful about this you will find that the AI gets things wrong predictably you're ambiguous as part of your prompts you're not giving it clear instructions about doing one thing or maybe it just constantly fails in a certain direction you have to give it direct give it you know prompting instructions to pull it back from making this kind of error you give it examples right to to guide it away from certain classes of error errors, but it's not like going to be a surprise why or how AI fails. Once you start prompting, you'll start to see patterns that you can prompt around to give instructions around. And what I like to say is like the biggest qualification for success here is whether you or whoever is working on the prompts of your company is willing to spend two weeks sleeplessly working on a single prompt to try to pass these emails. If you're willing to do that, you're in a really good place, right? It just it just takes such a grind because the thing is you're going to do these emails and at first you're going to pass like 60% of the time. And at this point most people just give up. They're like, "AI just can't do this task, right? They're like, I just can't. I'm not going to do it." And then you'll spend a night prompting and you're going to be at 61%. You're like, "Oh my god." The next group of people will give up at this point. What I'm here to tell you is that if you spend like solid two weeks prompting and adding more evals and prompting, adding more evals and tweaking your prompt and tweaking your prompt, tweaking your prompt, you're going to get to something that passes like 97% of the time. And the 3% is kind of explainable. It's like a human would it's like a judgment call almost. Humans make similar kind of judgment calls. Once you're there, you can feel pretty good about how this might interact in in in uh production. What I recommend is like pre-production, maybe in like beta, get to a 100, you know, tests per prompt and 100 tests for the overall task. If you're passing like 99 out of 100, again, you should feel pretty good about where you are, right? So, that's a just rough guide. If you can beat a thousand, that's 10 times better. Do that. But it's hard. It's actually really hard to come up with great evals. So, I'd recommend just at least 100, go to beta and put it in customers hands and set the expectation. By the way, this is not yet perfect, that's why you're in a beta. And then you listen and learn. Every time a customer complains, either you have their data because that's how your app is set up, or you ask them like, "Hey, can you share that document and that question you asked to see why it failed?" That's a new test. We've added much more eval at this point from real things that happened to real customers than the ones we came up with in the lab. And that's going to your customers are going to do the dumbest with your app. Okay? and they're going to do such dumb things that you'd not predict. But that's what customers really do. If you've ever seen like a real person's Google queries, they're barely legible, you know? And I'm assuming the same thing is true of chatbt. They see a bunch of stuff. Like your prompts probably look pretty smart. Most people are like burrito me how ouch or whatever. Like what do you do with that? Right? But you have to try to bring back a great result and determine what they're actually trying to say with these ridiculous prompts. So do it like those become your real tests and just keep iterating. This is not a static thing. New models will come out. Try the new models. Prompt fu and other frameworks make this really easy. Add a new model. It'll compute how well it does against your prompt so far. Keep tweaking your prompts. Um sometimes the addition or subtraction of a single word might move you up a single percent, but that's a very big deal if you're working in a field like finance, medicine, law where single percentage increases in accuracy really matter to the the customers you're serving. Right? Keep iterating. Never stop. There should be a new GitHub pull request like every other day or every day on your prompts. And I'm telling you, if you just do those two last slides, you know, how do the professionals really do it? Break it down to steps. Each step basically becomes a prompt or piece of code. And then you test each step. Test the whole workflow all together. If you just do these two things, you'll be like 90% of your way there to building a better AI app than what most of the crap that's out there, right? Because most people never eval. and they never take the time to figure out how professionals really do the job. And so they make these kind of flashy demos on Twitter. They maybe even raise capital and they may even be some of your like your heroes for a minute, but be careful who chooses your heroes. The real people are behind the scenes quietly building, quietly making their stuff better every single day. If you just do these two slides, you're going to be 90% of the way there and and better than most of the things that are out there. That's the craziest part. Okay, now the hardest part, honestly. the part that frankly we we are still trying to figure out postexit you know at a multi-billion dollar company uh it's still going to be really really really hard and I'm going to give some tips about marketing and selling AI apps in this new kind of world where you're maybe replacing or assisting a job things that we've learned along the way but the first thing I'll say this is a little bit counter to what I think is out there in a lot of the VC kind of a lot of people like say like the most important thing is sales and marketing a lot of people really really think that when you guys series A's and series B's, you'll have people on your board who say product doesn't really matter that much if you're really good at marketing and selling. And they've seen some examples of this working out like really well. I think it's We for 10 years we had an okay product at first. We went through different marketing and sales leaders, some of them super, you know, wellqualified, etc., and they did okay. When we had an awesome product, all of a sudden people were referring us by word of mouth. news was coming to us because we're doing something genuinely new and interesting, right? And that and word of mouth and news is free marketing. Um people coming to you like we had sales people because we had sales people from our older product that wasn't as good as the new one that we came out with with you know based on LLMs and I will tell you those sales people became like order takers. So the most important thing you could do for marketing and sales is to build a amazing product and then making sure the world knows about it somehow. obviously can't just like build it and not show anybody. Tree falling in the woods, nobody hears it. It's not going to do anything. But I do think that the quality of product matters so much more than your series A and B uh investors will say. So when you guys have those lame VCs on your board, you can think back to this talk and push back. All right. Um but it's still important. It's still important to market and sell. I have just three pieces of advice here. The first thing is uh you might not be selling traditional software anymore. Think about how you're going to package and sell it. The companies I'm most excited about right now are taking real services, like for example, reviewing contracts for a company and they're just doing it. They're like doing the full service. Maybe there's a human in the loop. And this would usually cost somebody $1,000 per contract to review if they went with a traditional law firm. They're charging $500 per contract. Again, for context, a lot of the tools you guys use right now probably 20 bucks a month. $20 per per month versus $500 per contract. We're talking about extreme step-ups in price. Price it according to the value you're selling it. Don't shortcom yourself. It's maybe a little in conflict with what I just said, but also listen to your customers for how they want to pay. Just ask them how would you rather pay for this. I'll tell you what we found out. We were thinking about a per usage pricing like this review viewing contract company and that that may work in some cases where they prefer to pay that way. That might work. But when we asked our customers, they said, "Listen, I'd rather pay more, but make it like consistent throughout the year, then potentially pay less and pay per use." So, our customers wanted to pay $6,000 per seat. They wanted per seat, and they want to pay $6,000 per se, 500 bucks a month. Fine. It's a situation where our customers wanted wanted predictable budgeting. Give it to them, right? Listen to your customers. The third thing to really think about when you're marketing and selling is all this AI stuff is new and scary. These big companies even, they want to dip their toes in the water. They want to try new things. Their CEO is like sitting on a board of people at a Fortune 500 company. The whole board is like, "What are you doing about AI?" And so their CEO is going to this company of like 20,000 people. What are we doing about AI? And they're like, "I don't know. I'm trying like Greg's product." Okay. They want to they want to try your product. But there's also this trust gap because they used to do this thing by asking people and they can fire people, they can train people, they can coach people like people are not perfect, but they're used to them. They are not they're not used to using your product yet. They have like no idea what to expect. So, how do you build trust? Some really smart companies are doing like head-to-head comparisons. Keep your law firm and then use our thing side by side and then compare. How fast are we? How good were we? How different were the results? keep your accountant use our AI accountancy and then compare like how different how offer we in our accounting or tax accounting or whatever it is offer that that's a great way to build trust compare it against people um do studies do pilots there are so many ways that you can do this but think think in your head how do I build trust with my customer and finally the sale does not end when they've written the check and definitely not when they started a pilot what I'm seeing right now is like an angel investor in this kind of post-exit world for for me is there are a lot of companies like our ARR is $10 million and you dig under the surface and it's like oh yeah we have a pilot for like six months and they pay us a lot of money for that pilot. Uh a lot of those pilots are not converting to real revenue and there's going to be a mass extinction event uh as a lot of pilot revenue. It's like instead of ARR is like PR like pilot recurring revenue or something that are not even recurring just pilot revenue I guess like is is not going to convert into real money and that's a real danger I'd say for startups right now even ones that are reporting super high numbers in terms of revenue big part of your job as a founder and a part of a job of the people you'll be hiring is making sure that everybody uses the product really understands it train roll it out consciously and this is different for every different industry for you know onboard board them really thoughtfully. Maybe that's in the app walking them through steps so they try different things. Maybe that's actually a person sitting next to them. I don't know if you caught this, but a very small kind of throwaway comment that Satcha said earlier today is that one of the most like growing roles at startups is these four deployed engineers, which I think is a really fancy term for just like boots on the ground people to sit next to your customer and make sure the product's actually working for them, right? Whatever it takes. One thing I said a lot in my company, I still feel this is very true, is that your product isn't just the pixels on the screen. It's not just what happens when you click this button. It's the human interactions with your support, customer success, with the founder, um it's training, it's, you know, everything around it. If you don't get that right, then you might have the best pixels on the screen, but you'll be beat by a company that that invests more in their customers and making sure that their products are actually well used. That's all you need to do to build a awesome AI app and beat our $650 million figure handily. All right, so open up for questions. >> Hello. Thank you so much for your uh talk. I wanted to ask about the process of choosing uh what kind of industry to go into to try to create more automation um in that way. So like if there are already competitors in that space, would you uh suggest looking at another industry or would you suggest trying to dive deeper into a niche of that industry or like how what would you advise in that situation? >> So so I don't think you should care about competitors at all. First of all, for some of these spaces, the market is so big because we're talking about like how much how many trillions of dollars are being currently spent on like marketing professionals or support professionals or whatever. There's not going to be a single company that's going to win this entire market for for the vast majority of them. And frankly, a lot of the times you're going to be at first scared of your competitors and then after you start building it, you're going to be dumbfounded about how bad they are and you're going to outbuild them out. You run circles around them. It's not about the competitors. But what I will say is like kind of diving deeper into like how to pick a market. The things I'd look at is um what are the kinds of roles that people are currently outsourcing say to another country, right? If it's something that they're willing to do that for, then that's probably a pretty good target for what AI could take over. Uh if it's a role where they feel like it's part of their identity to do it in house, you know, for example, I don't think you're going to outsource for Pixar creating the story of a Pixar movie, right? that is that is their that is they they feel whether they're right or wrong. Maybe AI in two years will just like do better Pixar than Pixar. But the people at Pixar are going to feel very strongly about the storytelling element. So, you know, don't try to outsource that part. Try to try to find the parts that are already outsourced. For example, find big markets, find where where there's a pain point across many different companies. Find um find things you know about or can get access to information about. Um these are the kinds of things I'd be looking at uh while trying to pick a market. But honestly, like there's so many huge markets. You could literally just print out like all the knowledge work stuff if you wanted to keep it digital. Throw a dart at everything you point out. Whatever the dart lands, just choose that market and start running at it and I think you're going to probably hit a trillion dollar market. So, um, competitors or not, don't care. >> Thank you. >> Perfect. Thanks a lot. So, um, Michael from Switzerland, uh, I have a quick question because you're a successful founder and, uh, many of us are going to found companies here. I wanted to know how uh has your focus changed across the different stages of companies from say the preede what did you focus on versus you know the C stages to the series A stages and finally to the exit end which part did you enjoy the most? >> Uh it's a great question Michael so I'll answer what I should have done and also what I did do. All right >> perfect thank you. What I should have done is at the seed stage focus on making a great product that gets product market fit and then at the series A stage focus on making a great product that gets product market fit and then at series B focus on making a great product makes great product market fit and then series C great product makes you know you can see probably the pattern here. What I ended up doing is I ended up focusing on all kinds of other things that didn't matter nearly as much as those things. And I think if you start from like you know because what is a company outside of its product like it's literally the service you're providing to your customers is through the product and if you focus almost entirely around that and become obsessive around that in my opinion um then a lot of other things will follow for example what people do we need to build a product that gets product market fit now you have like HR and recruiting etc to fill in for that that answer how are people going to find out about this amazing product that's marketing and sales um what culture do we need at the business to create a product that people love and really use. Now you have, you know, other parts of HR and setting the culture, which is a very important part of your job as CEO. So you end up as CEO focusing on all these different aspects by necessity, but all to that one end. And what ends up happening for a lot of founders because they read like medium posts and blog posts and they talk to their series A and series B investors is they end up focusing on HR or finance or fundraising or whatever not as means to the end of building great creating a big great product that gets product market fit but instead as an end to themselves like oh we need to have a greatly great culture in the abstract or we need to like now we need to hire marketing and sales. I did this. I fell into this trap. Big mistake you know. Um I would I would instead and this is I I'm very like as you can tell I'm one founder is very biased towards the product etc side but I think I feel very strongly. >> Hi Jake. So when I was 14 I sold my startup to deote um and like you I'm kind of looking for the next thing to do like in the exit acquisition stage. If you were here um at Y cominator startup school what would you be doing tonight? You know bar case text whatever you're doing what would you be doing here exactly tonight now that you're exited. >> It's kind of amazing. I exit at 40 and you exit at 14. >> Yeah. So, uh, you're already well ahead. It's awesome. Uh, actually, I feel like in some ways for us in the early days, focusing on legal made sense for us because I knew legal, but also was kind of a mistake because at the time the legal software industry, Gree LLMs is actually pretty small because it was like a fraction like you know lawyers make a trillion dollars a year sounds pretty good, but how much of that are they really spending on software? And the answer is like a very small amount. So no matter how well we did as a company, we just weren't going to make something that really changed that many lives um that really made that much money ultimately from a business perspective. Um and we were only making incremental changes to the workflow and outputs of the people we were serving pre-LM and postludden helped many more people and made them a lot more effective and changed many more lives. And I will tell you having existed in both spheres of making small impacts on a small number of people um and making only small differences their lives and contrasted with you know making a huge impact on many more lawyers in our our case making them way more effective and efficient replacing some of the work they were doing with LLM. Um the latter felt a lot better and I'm kind of addicted to that now. But I'd be focusing to long story short, I'd be focusing on the biggest problem you could possibly think of that is possibly solvable with the technology and skill set that you have. You know, like what do people want? People want what do what do businesses want? People want to be like skinnier and not like lose their hair. They don't want to do their laundry. They, you know, want to have uh everybody wants to have a cleaner show up to their house for eight hours a day and clean their whole house and make it spotless, but you just can't afford to do that. But could you make a robot that does that for you? Right? Is that a kind of pro product that can s serve everybody in the world? In fact, is that the kind of product that like the dishwasher in the 50s could unlock a lot of human potential because now people who are staying at home to try to take care of the kids are not having to clean up the house anymore, right? Because they can buy a $1,000 a year robot or whatever. There is so much you can unlock with like just thinking what is the biggest problem that most people face in businesses, you know, they want to market their products, want to sell their products, they want to make sure that people are doing great work. They want to replace certain parts of their work with like more consistent, more available. Like that's where I'd be focusing my attention is just use a huge problem that a lot of people have that you feel like you can solve and just go after it. Run as hard as you can. >> Great. Thank you. >> I think I have time for one more. >> Hey, I'm Sabo. Then I was wondering if you're making AI to be an assistant or replacement for a human, you could price that service based off how much time it saves a human or how much you would charge the human for as a salary. But if you're making something that AI is doing that humans could not possibly do, like looking through hundreds of thousands of like law documents per se, how do you price such a service? And I I want to be like really nuanced with what I said earlier. I think at first you can start charging what the humans charging and then you'll have competitors, they'll come in, they'll charge a little bit less and then other competitors will come in, they'll charge a little bit less and it's kind of beautiful. how capitalism works and it'll make the service cheaper and cheaper and cheaper and cheaper and at a certain point you know if unless you're in a very protected kind of space you will end up charging a lot less than the people were which I think is probably a good thing at the end of the day for society right bad for your business good for society uh because now you can have the services of a lawyer but for like 10 cents on the dollar one cents on the dollar for that new category of like you know I I would I would start from what's the value what's the value that you're providing to the business start there if they're going to save $100 million doing this or would have paid $5 million to do this. Okay, take 10% of that, 20% of that, you know, have a conversation with your customer. How much is you willing to pay to solve this problem for you is probably the best place to start. I actually have time for one more question rapid fire. It's a super fast one. >> Hi, Jake. Uh, congrats on your exit. Um, I know you probably get this question a lot, but when you're building things with prompts that are based off of models that may not be proprietary, how do you build defensibility and not end up as a GPT wrapper? Basically, >> my fastest answer. Just build it. And as soon as you build it, you'll see how hard it was to build it. How many little pieces you have to build, how many data integrations, how many checks, how fine-tuned the prompts need to be, how you have to pick your models super well. And when you do that, you're going to find that you built something that nobody else can build because you spend like two years just doing nothing but that. So, I'm not scared. Don't be scared. All right. Thank you, everybody.
