Exa Labs Inc., a San Francisco-based company developing an AI-focused search engine, raises $250 million in a new funding round that values the business at $2.2 billion. Multiple outlets report the financing as a Series C round announced on May 20. The round is led by Andreessen Horowitz, with Exa presenting the raise as support for building and scaling its technology for the next generation of models. Exa describes its goal as creating search infrastructure designed for the age of artificial intelligence. Following the investment, the company’s valuation increases to $2.2 billion, reflecting investor interest in AI-native search and related infrastructure. Both reports characterize the funding size, timing, and valuation similarly, though they emphasize different aspects—one highlighting the valuation headline and Andreessen Horowitz’s role, and the other focusing on how the funds are intended to train future models and scale systems. No additional details about other participating investors, specific product milestones, or financial terms beyond the valuation and round size are provided in the excerpts.
