Exa, a developer-focused AI search engine, has secured an $85 million Series B funding round, bringing its valuation to $700 million. The funding round was led by Benchmark with participation from Lightspeed, YCombinator and NVentures. 

Founded in 2021, Exa built a search engine specifically for AI applications, aiming to surpass traditional search engines designed for humans. Its products include a search API and Websets, a high-compute search product for comprehensive queries, with a focus on providing high-quality knowledge without benefiting from advertising-related incentives. The company also offers features like customization and Zero Data Retention for enterprise clients.

With its new funding, Exa plans to expand its indexing and processing systems, acquire a larger GPU cluster for research and grow its team across various departments, including engineering, go-to-market and operations. The company’s ultimate goal remains to organize all information so that AIs can achieve “perfect search.”
