Waymo had to reinvent itself before it could move a car

Waymo is the Alphabet self-driving car company, and it's been around for over a decade. The thing about building a robotaxi fleet is that the software doesn't just sit on top of a car — it has to run the whole thing. So Waymo ended up redesigning the vehicle from the ground up, building its own sensors, its own computers, its own safety stack. The result is a car that can't be bought at a dealership.

The company has been quietly building this thing for years, and now it's rolling out in a few cities. The approach is different from most of the industry: instead of retrofitting a regular car with sensors and hoping the algorithms handle the edge cases, Waymo built the car to work with the software. That means fewer parts, fewer failure points, and a system that's easier to test and maintain.

Why this matters for us: this kind of vertical integration is how you actually ship a product that works — not the patchwork of off-the-shelf parts and borrowed code that most startups are forced to assemble.
