About
Exa AI is an AI-native search and retrieval company building a fundamentally different kind of web search infrastructure designed specifically for AI systems and developers. Founded on the premise that keyword-based search engines are poorly suited to serve as data sources for large language models, Exa developed a neural search architecture that retrieves web content based on semantic meaning rather than keyword matching — enabling AI applications to find relevant, high-quality information the way reasoning systems think about queries.\n\nExa's API allows developers to perform meaning-based web searches, retrieve full page contents, find similar documents, and access curated data streams for AI training and retrieval-augmented generation pipelines. It is designed as AI infrastructure: the underlying retrieval layer that powers AI agents, research tools, and automated workflows that need accurate, current web information. Target customers are AI developers, research teams, and enterprises building AI-powered products that require reliable web grounding.\n\nExa AI raised $85M in a Series B at a $700M valuation in September 2025, backed by Nvidia and Benchmark Capital. The company's revenue hit $10M with 1,010% year-over-year growth — one of the fastest growth rates in the AI infrastructure category. Nvidia's strategic investment reflects Exa's importance as a retrieval layer in the broader AI stack. As AI agents proliferate and need reliable access to real-time web knowledge, Exa's semantic search API is positioned as essential infrastructure for the next generation of AI applications.
