Traction
as reported by the founderUsed by over 500,000 developers and powers platforms including Cursor, Cognition, Hubspot, OpenRouter, and Monday.com.
Traditional search engines are optimized for human clicks and ad revenue rather than the structured, semantically relevant data required by AI systems.
The company operates within the generative AI and enterprise software markets, specifically targeting the growing demand for AI-native search and data retrieval tools. It competes by providing superior performance on retrieval benchmarks such as FRAMES and Tip-of-Tongue.
Exa provides a custom search engine and API that returns clean, machine-readable content and embeddings, allowing AI agents to perform research and retrieve information more efficiently than standard keyword-based search.
