1/ Huge congrats to the @DoorDash team on today’s IPO! As the team celebrates today's milestone, I thought it would be fun to take a walk down memory lane. Here’s a snapshot of the internal memo I published on DoorDash in 2014, just before our Series A partnership.

2/ Customer empathy: @t_xu grew up washing dishes in restaurants where his mother worked while she saved up for med school. He understood the struggles small-business owners face: how hard it is running a restaurant, how thin the margins are, & how little room there is for error.

3/ After founding @DoorDash, Tony moonlighted as a driver for companies like Papa John’s – all to learn how those companies operated and recruited drivers. He also regularly tested out DoorDash’s system on busy shifts.

4/ This customer obsession served as the foundation for @DoorDash's mission to grow and empower local economies – starting first with the *merchants* in the suburbs (not a focus for their competitors).

5/ *Data mindset*: @DoorDash wasn’t the first food delivery service. But their technical approach to problem solving enabled them to break down logistical issues, simplify processes, and minimize errors.

6/ The team also knew early on, for example, that their software around batching would become a competitive advantage. They understood that local delivery was different from the transportation business.

7/ Over the years, @t_xu @andyfang @stanleytang & team have continually shown a deep understanding of their customers, unparalleled operational efficiency and ongoing resilience. Congratulations on today’s milestone! We look forward to working with DoorDash for many more years.
