Statements from this episode (32)
Dalton Caldwell: Elite founders need coaching on basic fundamentals, not complex tactics
“Even if you're the best in the world, being coached and being reminded of the fundamentals and basics is what puts you in the right mindset and that you already know everything, right? You're at the top of your game. If you make it to the elite levels of being…”
Caldwell: Successful startup founders rationally should have quit at some point
“If you look at all the startup stories that we have at YC and all the companies we funded over all the years, the underlying theme is that rationally the founder should have given up at some point.”
Caldwell: Airbnb founders' decision to keep going was purely irrational
“When they probably should have shut down like three or four times before they got into YC. It objectively wasn't working. They were basically ruining their lives. They were disappointing their parents. Everything was wrong. And it was a purely irrational act f…”
Caldwell: Startup success requires irrational persistence through multiple near-death experiences
“Across the portfolio of YC and non YC companies, there has to be this irrational, you know, intention to keep going even when the world tells you it's not working and you feel completely defeated. And you likely have to go through this many times and have thes…”
Caldwell: Shutting down a startup is forgotten within 10-20 years if handled with integrity
“No one will remember that you shut down your company probably in 10 years or 20 years, like time, as long as you have integrity. As long as you're an honest person, as long as you handle yourself well through good times and bad, people will remember you fondly…”
Caldwell: Brex and Retool appeared to be their YC batch's worst startups
“Vyond Change their idea and got really excited about it and renamed to Brex. And this was Brex, which is like a Decacorn. And Cashew changed their idea and renamed to something called Retool. And so out of my 35 companies, the ones that objectively seemed the …”
Caldwell: Successful pivots move closer to founder expertise and prior learnings
“Usually a successful pivot gets warmer instead of colder from what you're an expert at and somehow builds on what you learned on the prior idea.”
Caldwell: Founders should pivot when out of growth ideas, not before
“Like if it's not going well and you're out of ideas, that is usually a good time to pivot. But when there's a, you know, you have like half a dozen or a dozen really good growth ideas that you haven't tried yet, try them, right?”
Caldwell: Founders can find big markets by targeting hated enterprise incumbents
“My suggestion was to start by looking at what companies are publicly traded and or owned by private equity that are large and that also are hated by their customers. And to try to intentionally find where there's a knowable big market within a comment. Combine…”
Caldwell: Identical information diets cause founders to create identical startup ideas
“If you just are following the same principles and have the same information flow into your brain, you're going to come up with the same ideas as everybody else. And so the prompt here is to try to go more off the beaten path, either from your personal experien…”
Caldwell: Tar pit startup ideas generate positive feedback and persuasive arguments
“The weird aspect of what we call a tar pit idea is an idea that a lot of people come up with, and then it seems like an unsolved problem and you get lots of positive feedback for, right? And you have a really good set of arguments that it's a really good start…”
Caldwell: Music discovery is a classic tar pit startup idea
“Honestly, I worked on Tarpon ideas myself as a founder, which is a music discovery. This is something I did in my first startup. That was definitely, you know, Music startups are hard. And trying to be like, oh, we're going to fix music discovery. This was cla…”
Caldwell: VCs reject good pitches because they get limited shots per year
“It's that you only get so many shots as an investor. And so anything that doesn't seem like this is the one I want to do is a no. And that that's actually why they're saying no versus this, you did, you know, oh, you had a bad zoom setup or something, you know…”
Caldwell: Rigorous TAM calculations at the earliest stages are misleading
“The earlier you go, the less it matters. And some of the most phenomenally good startups, if you were really pedantic about it, the TAM would be like tiny. Like the TAM of Uber would be like nothing, right? Like how the TAM of Airbnb would have been nothing.”
Caldwell: Razorpay looked like a tiny TAM before Indian card usage exploded
“I was a, I funded Razorpay, which is I think the largest payment processor in India. And the TAM of that was tiny because no one was using credit cards in 2015 in India. So you had to believe that the size of the credit card industry in India would like a hund…”
Caldwell: Great product founders stay in the weeds and talk to customers indefinitely
“The folks that are really great at product, the founders that are always deeply in the weeds on product and still care a lot and are still talking to customers no matter how late stage it gets.”
Caldwell: Investor pressure to hire big-tech executives often leads to startup failure
“You get pushed often by investors to hire executives or to scale the team, or we need, you know, We need, we re you raise all this money. You got to spend it. You know, we got to, you got to show you're serious about growth and building a world-class organizat…”
Caldwell: Startups usually die from founders losing hope, not running out of cash
“It's pretty rare. I would argue that the cause of death is that they had lots of firepower and they were feeling really positive and they just ran out of money. That's actually like more rare than founders think. It's much more common that they still have some…”
Caldwell: 100% of startup founders experience a near-death moment
“If we define it as the company had a near death experience where it was going poorly and the founders seriously wondered if it was all going to be over a hundred percent of the time people go through that, you know, with the founders like, yeah, I guess we're …”
Caldwell: Founders use landing pages and ads to avoid awkward customer conversations
“And I think a lot of folks, their inclinations are to like, you know, build a landing page and buy some Instagram ads and try to get people to sign up for something. And again, maybe I, maybe that's something, but I think a lot of the reason people do that is …”
Caldwell: Founders should spend 20% to 30% of their time on customer calls
“I think it's look at your calendar and there should be, you know, 20 or 30% of your time that the calendar says something like customer Meeting, customer call, like meeting with foo, meeting with this person. And when the calendar is not that, or it's all, you…”
Caldwell: Getting a yes does not finish the startup sales process
“And I think the takeaway from that story is even when you get a yes, you're not actually done with sales. You have to finish the last mile to get the thing implemented.”
Caldwell: Patrick Collison personally checked in weekly with early Stripe customers
“I was an early Stripe customer at my startup and yeah, Patrick would like we used Google talk at the time. Patrick would be sending me messages like on a weekly basis, just like checking in. And so again, it's funny how successful these folks get, but yeah, Pa…”
Caldwell: Outlier founders share deep internal conviction and refusal to fail
“The thing that I would argue folks that build really big companies have in common is they just really want it and they really believe in themselves and they really believe they can make it work. And that they're somehow deep in their internal psyche. There's s…”
Caldwell: Conviction builds via a virtuous cycle of customer feedback
“I think you build conviction and you have this like network effect virtual cycle where you get more conviction, the more customers reflect back to you and data reflects back to you that you're on the right track.”
Caldwell: LLMs will drive successful enterprise integration startups
“Likely LLMs will improve, like we'll probably be able to create better and better blue. So all sorts of software systems can talk to each other. And so again, very broad idea, but yeah, I think we'll see a lot of very successful companies where that's the kern…”
Caldwell: Instagram was a free knockoff of Hipstamatic combined with a social graph
“And so they basically built a pretty legitimate knockoff of the Hipstamatic filters, combining it with a social graph and they launched it and it pretty quickly took off. So of course this is Instagram.”
Caldwell: Andreessen Horowitz passed on Instagram due to a conflict with Picplz
“And basically because Andreessen Horowitz had like invested in my company was on the board, even though they were investors in Instagram That was like a conflict and they didn't do the deal.”
Caldwell: Growth hacking and A/B testing waste time for early startups
“I think growth and growth hacking and doing all this analytics, AB testing stuff is a total waste of time for very early startups.”
Caldwell: Founders should study how tech giants got their first 1,000 users
“The way to extrapolate that is know what your comps are of what companies you, your archetype is, and then look at what they did on the zero to one and ignore what they do today. Right? Don't pay attention to what Facebook does today if you're a brand new star…”
Caldwell: Founders should validate and pre-sell before writing code or raising money
“If someone wants to do a startup and doesn't know where to start, just to give you permission to talk to potential customers and try to pre-sell something before you write code and have those conversations. I think so many folks don't know where to begin on st…”
Caldwell: Reading popular sales books gets founders 80% of the way
“I think a lot of founders are afraid of doing sales and they don't know how to do sales and they think they need these really experienced sales coaches and they need all this training. And I'll be like, well, go onto Amazon and Find the most popular sales book…”
