Exa CEO Will Bryk: Machine Searches Will Overtake Human Searches in 2026
AI Engineer · youtube · 2026-09-16
AI Engineer interviews Exa founder Will Bryk on building the search engine for the agentic web.
- Crossover year: Bryk shows a 30-year chart of web searches per day and predicts 2026 is when machine-issued searches surpass human-issued ones for the first time, with the gap potentially growing a thousandfold.
- Perfect retrieval thought experiment: a language model judging whether one query matches one document works extremely well; running it across a trillion documents yields perfect retrieval at $10 million per query. Exa's entire mission is driving that down nine to twelve orders of magnitude.
- Origin story: founded in 2021, launched a consumer search engine in 2022, then a stream of Twitter DMs requesting API access — including from the roommate downstairs — revealed the real business: search for agents.
- Search purpose: mainstream engines are built to recommend, not answer (search "shirts without stripes" and you get striped shirts); agents need the opposite.
- Also covers complex/fast queries with fewer tokens, a marketplace for private data, and compressing a year of research into a second.
