I ran a product used by 2 billion people. Then I chose to run a company that delivers groceries. People thought I was crazy. I wanted to be CEO.

Instacart is not a delivery company. It is an advertising platform that happens to deliver groceries. That distinction is worth billions.

Profitability in delivery is not impossible. It just requires making advertising revenue larger than delivery losses. That's what we did.

At Facebook, I learned how to build products for billions. At Instacart, I learned how to build a business that actually makes money. Both skills matter.

I moved from the south of France to Silicon Valley with no network and no connections. If you have the skills, the system eventually lets you in.
