# EXA Raises $250M Series C: Search Engine for AI Agents

> Exa has closed a $250 million Series C at a $2.2 billion valuation, led by a16z, to build what it describes as a search engine designed from the ground up for AI agents rather than people. The company already tracks more than 500 billion URLs and serves over 400,000 developers and 5,000 companies, with customers including Cursor, Cognition, HubSpot, and Monday.com. Alongside the raise, Exa is leaning into its Agent API, which combines frontier models with its search index to handle exhaustive research, list-building, and entity enrichment. The core thesis is a striking one: the company expects AI agents will eventually generate more searches than Google processes today, which would require retrieval infrastructure built for machine consumption rather than human browsing. The capital is earmarked for scaling that infrastructure toward well over 100,000 searches per second, and Exa has brought in a former LaunchDarkly president as chief revenue officer to push commercialization. If the agent boom plays out anywhere near the way its backers expect, the plumbing that lets those agents read the web could become as valuable as the models themselves, which is the bet a16z is making here.
