How Will Bryk built Exa
Bryk grew up in New York and met Jeff Wang in their first year at Harvard; as roommates they built a search engine together (Exa). After graduating he joined Cresta as one of its first engineers, building real-time AI products, and wrote a book about the history of civilization in his spare time. “When I realized the future of civilization depends almost entirely on the quality of information we consume, I left to start Exa,” he writes (Y Combinator).
The idea, in 2021, was a better Google: “Transformers normally predict the next word. We train our search engine to predict the next link” (TechCrunch). Metaphor’s search engine launched in November 2022, two weeks before ChatGPT. When AI developers asked for its results through an API, Bryk turned the company toward search for AI, which took revenue past $100 million a year by October 2026. He calls Exa “the OpenAI of search… a research startup that does like fundamental research” (Latent Space).
Will Bryk’s age and net worth
Bryk was 27 in July 2024 (TechCrunch), and graduated from Harvard in 2019; no birth date has been published. No estimate of his net worth has been published either. Exa is private, valued at $2.2 billion in May 2026, and the founders’ stakes aren’t disclosed.
Jeff Wang, Exa’s co-founder
Jeff Wang studied computer science and philosophy at Harvard, where he ran a GPU cluster in his dorm room and shared a room with Bryk, then spent three years building data and web infrastructure at Plaid (Exa). He was 26 in July 2024. He sits on Exa’s board and now works on how Exa sells, building what he calls knowledge systems for go-to-market teams.

“Because Google makes money from ads, they’re not actually optimized to build the best general search engine in the world.”
