WHAT IT’S REALLY ABOUT

Why Airbnb, Coinbase, and Stripe Succeeded Despite Being Called Bad Ideas

  1. Seibel and Caldwell argue that Airbnb, Coinbase, and Stripe shared three themes: good timing against weak incumbents, widespread dismissal as bad ideas, and markets bigger than the founders first realized.
  2. Airbnb entered a market with VRBO and CouchSurfing but improved on them by facilitating payments and not charging hosts upfront, an insight partly gained from the founders using their own product.
  3. Coinbase offered a simple, safe way to buy Bitcoin when options were scams or unreliable exchanges like Mt. Gox, and even its founder undercounted how valuable that single feature was.
  4. Stripe fixed the painful process of accepting credit cards by treating developers as the customer, with excellent documentation and a site built for them, and it was the most expensive product in the market.
  5. The hosts conclude that founders should ignore existing competitors, disregard experts who aren't users of the product, and be wary of dismissive market size math.

IDEAS WORTH REMEMBERING

5 ideas

A 10X improvement on a weak incumbent beats being first

None of the three companies was first to market, but existing products like VRBO, CouchSurfing, Mt. Gox, and Authorize.net were painful enough that a far better version was within reach.

Solving your own problem produces real insight

Airbnb's founders needed rent money, and Brian realized payments were needed after forgetting cash and being seen as a fraud. Stripe's founders saw their YC peers struggle with payments.

Conventional wisdom would have killed these companies

Investors and founders thought charging on Airbnb was a mistake, Bitcoin was a bubble, and two teenagers in regulated payments was a suicide mission. Seibel says eight of ten experts would have called them stupid.

Know your real customer and build for them

Stripe asked what a programmer would want and built beautiful documentation and a beautiful website, creating buzz on Hacker News and a hot beta. It was also the most expensive option, yet people were desperate for it.

Simple products that solve the right single problem can be enough

Early Coinbase let you log in, enter an amount, and buy or sell Bitcoin, with no graphs, news, or social features. Caldwell says this was enough to build a $100 billion company.

WORDS WORTH SAVING

5 quotes

They had to be contrarian to walk down this path because if they had asked 10 startup experts, 10 investors, 10 fellow founders, eight of them would have told them that they were stupid.

— Michael Seibel

Talk is cheap, execution's hard. Execution's expensive, and they ha- all these folks had to execute.

— Dalton Caldwell

If all of your smart technical friends are complaining about the same thing, maybe it's a real problem.

— Michael Seibel

It was like if Steve Jobs had to design a payments company, it would be Stripe.

— Dalton Caldwell

Be very careful about pretending that you know how big the market could be. It turns out with so many of these transformational technologies, there are use cases you can't dream of, that once you build a 10X better product, other people will do.
