DoorDash CEO Tony Xu had a confession to make. When his four-person team applied to Y Combinator in the spring of 2013, they pegged their company’s lifetime potential at $100 million in revenue. That number felt aspirational at the time. Fortune reported Tuesday that DoorDash now generates $4 billion in a single quarter.
“Thankfully, we’re a few orders of magnitude off,” Xu said on the Uncapped with Jack Altman podcast. He was talking about his original $100 million estimate. The company he and his co-founders built from 150 customers and $10,000 in sales is now valued at $87 billion.
Xu’s message to other founders is direct: stop capping your ambitions. “You have to take the greedy algorithm,” he said. “You have to keep going all the way and seeing if there’s more.”
What This Actually Means
There’s a specific psychology trap founders fall into early. You’re working from an apartment, you have no proof your idea scales, and your investors want a financial model. So you build one that seems “realistic.” You prove you’re not crazy. You prove you’ve thought about the risks.
Xu’s story punches a hole in that logic. A conservative estimate doesn’t just affect your pitch deck. It shapes how aggressively you hire, how boldly you expand, and how big you’re willing to fight. If you’ve already told yourself the ceiling is $100 million, your decisions will reflect that ceiling long before you ever hit it.
DoorDash reached that $100 million annual revenue mark in 2018, five years after Xu wrote it down. Now they clear it in about nine days. That’s not just execution. That’s what happens when the founders refuse to stop. According to Fortune, orders across America and more than 40 other countries grew 27% in Q1 2026 alone, reaching 933 million total orders in a single quarter.
If you’re building right now and you’ve written a conservative projection to make your plan look sensible, Xu’s story is worth sitting with. The choice between bootstrapping and raising capital isn’t just financial. It’s about what future you’re actually building toward.
The Numbers Behind It
DoorDash’s Q1 2026 revenue came in at $4 billion. That’s 40 times the total revenue Xu originally projected, delivered in a single quarter. When they applied to Y Combinator, they had 150 customers and $10,000 in lifetime sales. The company now processes nearly a billion orders per quarter across more than 40 countries.
Those numbers don’t exist in a vacuum. According to the SBA, there are 33.2 million small businesses in the United States. Most of them will never reach $1 million in annual revenue, not because their idea wasn’t good enough, but because founders underestimate what’s possible and then build a company sized for that underestimate. The data bears this out: the Federal Reserve’s 2025 survey found that 43% of small business owners work 60 or more hours per week. The hustle is there. The vision is often the bottleneck.
Xu isn’t alone in his philosophy. Chess.com cofounder Danny Rensch, who scaled a platform to a $1 billion valuation that many thought was a niche play, told Fortune last year that delusion is literally a prerequisite. “The belief that you see something that doesn’t exist yet, and how delusional that is, is the requirement for every successful entrepreneur,” Rensch said. Billionaire Mike Repole, who sold Smartwater and Vitaminwater to Coca-Cola for a combined $9.7 billion, said it plainly: “Crazy people change the world.”
The Hustler’s Library Take
The lesson here is not “dream big” as a bumper sticker. The lesson is that your first financial model is almost certainly too small, and you need to know that going in so you don’t build a business infrastructure that can’t scale past your own conservative guesses.
Xu framed it as a “greedy algorithm” — a computer science concept where you make the locally optimal choice at each step to find a global best solution. In founder terms: keep pressing forward until there’s genuinely nothing left to build. Don’t preemptively decide the ceiling before the market tells you what it is.
This also matters for how you position yourself with investors and partners. If you’re building something that could be a $10 billion business and you’re pitching it as a $10 million business to “seem credible,” you’re not being smart. You’re limiting who shows up to help you build it. The tools available to founders today, from AI to global logistics infrastructure, mean the gap between a local business and a global one is narrower than ever before. Your model should reflect that.
What You Should Do
First, go back and look at your revenue projections for the next three years. Ask yourself honestly: did you write those numbers because the data supports them, or because they felt defensible? If it’s the latter, rebuild them with a “what if this actually works” assumption and see what changes in how you run the company today.
Second, stop treating “realistic” as a virtue when pitching your business. Serious investors don’t fund realistic. They fund founders who can articulate a large outcome and have a credible path to it. Xu’s Y Combinator application got funded with 150 customers. The vision was always bigger than the current traction.
Third, audit your strategic plan for ceiling-setting language. Phrases like “we want to capture 5% of our market” often reflect a founder who’s already decided to stop. Markets don’t cap themselves. Founders do.
And finally, read the DoorDash Q1 2026 investor report yourself. Not because you’re building a food delivery company, but because it’s a real-time case study in what happens when a team refuses to treat their early projections as a finish line.
The ceiling you set today is the company you’ll build tomorrow. Make sure it’s the right one.
