About Exa

Exa AI develops search infrastructure and APIs designed for AI applications and agent-based workflows. The company uses neural search and web-scale indexing systems to retrieve and organize information based on semantic meaning rather than traditional keyword matching. Its platform provides tools for web search, content retrieval, company search, and data enrichment that developers can integrate into research, automation, and retrieval-augmented generation workflows. Exa also maintains infrastructure for large-scale crawling, indexing, and processing of web data to support high-throughput search operations. The company’s products are primarily used by developers and organizations building AI-powered applications, research systems, and automated knowledge tools.
