Exa Labs raises $250M for agent-native search infrastructure

Exa Labs closed a $250M round at a $2.2B valuation led by Andreessen Horowitz, announced 20 May 2026. The thesis: "search for agents" is now a distinct category, separate from consumer search products like Perplexity. The same TechCrunch piece noted Parallel Web Systems closed $100M in the same window. Signal: the AI search infrastructure category has graduated from sub-bet to standalone wedge worth nine-figure rounds. Whether the economics support that many specialised search-for-agents providers is the question nobody is asking yet.
