Exa operates a search API aimed at AI applications and agents and describes itself as building the market-leading search engine for AI. Its API serves over 5,000 companies and more than 400,000 developers, with customers that include Cursor, Cognition, HubSpot, and many Fortune 500 companies. The company emphasized that AI agent searches will grow far beyond traditional human search patterns and positioned its product to meet that demand. Exa raised $250M in a Series C at a $2.2B valuation led by Andreessen Horowitz, with existing investors increasing their commitments. The announcement noted that board member Sarah Wang is joining as part of the round. The company also signaled intentions to make its search APIs significantly cheaper and to open source much of its work in the future.
