How Airbnb and DoorDash Succeeded: First Principles
What society imposes on us is the wrong kind of thinking: one that is based on analogy and credentialism instead of first principles thinking. But how do we break free? Here are 3 ways to do it.
You get up, you brush your teeth, you eat cereal. You go to school, do as you’re told, sit up straight, show up on time, don’t talk back. Be a good person. Fit in. Don’t make waves. Stay in your lane. The nail that sticks out is hammered down.
But isn’t that the problem? A whole system, a whole society, a whole civilization dedicated to telling you how to live and what to do and how to think. There is a way to break out and it’s a way that repeats over and over again. The founders I’ve worked with have gone on to create massive businesses.
What do you need to break out of it? First principles thinking.
Can you start with what you are absolutely sure is true? Can you have direct experience with a thing or get more experienced such that you can make a more well-informed decision or guess as to how something works or the state of a particular thing?
Remember where we started: the classroom, the workplace. These places, where we sometimes spend years and years of our lives, are designed to teach you to stay in the box that you live in. You learn the history. You learn how it’s been done and then you were programmed to believe that that is how they will be for forever. And this is where first principles thinking can help you. Because in contrast, you will end up challenging the preconceived notions and the thinking by analogy that the rest of the world has imposed on us.
There are ways you can make something new and different and it starts with three things I think you need.
First Principles Thinking in 3 Steps
- Curiosity.
- Empathy.
- Serenity.
Curiosity
Asking questions and digging further to understand how those systems work. One of the key ways to do this is actually the five whys analysis. It’s something that the Toyota production system came up with years ago in Japan.
Here’s one of my favorite examples from a blog post by Eric Ries, the creator of the Lean Startup.
Five Whys in Action: Website Crash
- Why was the website down? Well the CPU utilization on our front end servers went to a 100%.
- Why did the CPU usage spike? Well, some code contained an infinite loop.
- Why did that code get written? A programmer made a mistake.
- Why did that mistake get checked in? He/she didn’t write a unit test for the feature.
- Well, why didn’t he/she write a unit test? He/she’s a new employee and wasn’t properly trained to do test-driven development.
Root Cause: Lack of Training

So if you ask why it will allow you to fully explore why something happened. Eric says:
“Because the most common problems keep recurring, your prevention efforts are automatically focused on the 20% of your product that needs the most help. That’s also the same 20% that causes you to waste the most time. So five whys actually pays for itself awfully fast and it makes life noticeably better almost right away.”
The five whys is why the Toyota production system made Toyota so successful. Today we think Japanese cars are incredibly reliable, but they had to come up with a process to get there. And curiosity is a key part of understanding why things are and then how to fix it.
Empathy
Getting an intuitive sense for the lived experience and feelings of other people, particularly customers. Listening to users and getting their direct experience is something that a lot of people know how to do. When you do it well, sometimes it can help you create a billion dollar startup.
Airbnb just had an incredible IPO, but when it first came out, a lot of people said it wasn’t going to work. It was literally just air beds and breakfast. Brian and Joe at Airbnb worked on something that was kind of a fringe idea. They needed money for rent and a design conference was in town. They thought they could make rent by making a website and letting people crash on the floor of their San Francisco Soma loft on Roush street. Here’s Brian describing what it was like to host people for the first time:
“We ended up hosting 3 people from around the world. A 35-year-old women from Boston, a 45-year-old father of 5 from Utah, and a 30-year-old from India. And now I got to tell you, the reason we started doing this is because we thought it was funny, cool and we make money. And because we had to make rent. There’s something that happens though when somebody lives with you, though. It’s kind of like the arc of a friendship gets contracted from a year or to a day. In other words, if you were to meet somebody maybe here at Stanford or in the real world, and you get to know them, how much time does it take to invite them over your house and have dinner with them? It might take like months, even a year. You don’t just get to know people. We realized it contracted this year-long friendship into a couple of days. So these people came as strangers and they literally left us friends. We ended up keeping in touch with them. In fact, one of the guests ended up inviting me to his wedding. The other guests, this woman moves from Boston to San Francisco, and I think we’re realizing there’s a bigger idea here.”
This is a really interesting experience in empathy because it was so direct. You can’t get closer to someone than literally sleeping under the same roof with your users. And what they heard in that first experience was what they use to pursue that idea. They had direct experience, which gave them direct belief and conviction that this was something that was going to work. Airbnb is now worth more than $100 billion and counting on the public markets.
Serenity
Third and most counterintuitively, you need serenity. The ability to accept things that you cannot change. This is from the serenity prayer by theologian Reinhold Niebuhr:
“God, grant me the serenity to accept the things I cannot change, courage to change the things I can and the wisdom to know the difference.”
One of the best recent examples is actually DoorDash. I worked with the startup at Y Combinator. They reached 50% market share in the United States through a brilliant mix of strategy, but also extreme customer focus.
Now picture this, you’re DoorDash. Your competitors, like Uber, have incredible access to capital and they’re fighting it out in the cities in a pitched battle for market share. Early DoorDash employee Michael Bloch recounted this in a recent tweet storm.

Seamless had a 17 year head start. Uber had 50x DoorDash’s marketing budget. So DoorDash retreated and retrenched to Long Island, New Jersey, Westchester, and Connecticut. They found product market fit there and were profitable in a matter of months.
DoorDash had the serenity to accept things they could not change. They went to the suburbs where their competitors were not. And here’s the key thing. They took the profits in the suburbs and won the cities and a capital war. There are two ways to win. One is just to raise more money. But what can you do if you can’t raise more money? You’ve got to do what DoorDash did – be more profitable, outflank and outsmart. Don’t fight a losing battle. Fight the battle you can win. DoorDash is now worth over $55 billion on the public market.
If you have first principles thinking, you’ll have the curiosity, the empathy, and the serenity to find a better path. You’ll break out of the standard script. You’ll go direct. You’ll learn more about the customer and you’re going to fight the right battles. You can win this.
