Last week, Exa took over SF's Pioneer Building, previously home to Stripe, OpenAI, and most recently xAI. Elon assembled the Colossus cluster here (his mattress was still lying there during our tour). Alec Radford trained GPT-3 here. The Collison brothers built the web's financial backbone here. They were all infra companies: Stripe -> Financial infra OpenAI -> Intelligence infra xAI -> Compute infra Each entered Pioneer as a small startup with enormous ambitions and left as a foundational layer for the world. Exa -> Information infra We entered Pioneer as web search for agents, but by the time we leave we'll have organized all the world's data into a foundational information layer. This will require things like deploying satellites, new misinformation detection algorithms, and embedding retrieval on an outrageous scale. Whatever is necessary to keep billions of people and trillions of AIs as informed as possible. A trusted information ecosystem is necessary to safely navigate this chaotic AI era, an era that was set in motion by our previous occupants.
