## Summary

AI-native search API raised $85M Series B at $700M valuation in Sep 2025 backed by Nvidia and Benchmark; revenue hit $10M with 1,010% YoY growth; powers semantic web retrieval for LLM and RAG pipeline applications.

## Company Overview

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.

## Frequently Asked Questions

### What makes Exa different from Google Search?
Exa built a neural search engine optimized for AI agents, using semantic understanding rather than keyword matching to retrieve precisely relevant web content via API.

### How much funding has Exa raised?
Exa raised $85M in Series B funding in September 2025 led by Benchmark, at a $700M valuation, with total funding of $111M.

### Who uses Exa?
AI companies and developers use Exa's API to give their agents and applications access to high-quality, real-time web information for tasks like research and data retrieval.

### What is Exa AI and how does it differ from traditional search engines?
Exa AI (formerly Metaphor) is a neural search engine designed specifically for AI applications. Unlike keyword-based search engines, Exa uses embedding-based search to find semantically relevant results, making it ideal for AI agents and LLM-powered applications that need to retrieve high-quality, relevant web content based on meaning rather than exact keyword matching.

### What types of queries is Exa AI best suited for?
Exa AI excels at open-ended queries, similarity search ('find me content like this'), and research-style queries where semantic relevance matters more than exact keyword matches. It is particularly valuable for AI agents that need to autonomously gather information, fact-check responses, or discover relevant sources on complex topics.

### How do developers integrate Exa AI into their applications?
Exa provides a clean REST API and Python/JavaScript SDKs that developers can use to integrate web search into AI applications. The API returns structured results with cleaned webpage contents, making it easy to feed high-quality context into LLMs without dealing with raw HTML parsing.

### What is Exa AI's pricing structure?
Exa AI offers usage-based pricing with a free tier for low-volume experimentation. Paid plans are based on the number of search queries made per month, with higher tiers offering faster response times, higher rate limits, and access to additional features like full page content extraction and domain filtering.

### How does Exa AI handle web content quality and freshness?
Exa continuously crawls and indexes the web, maintaining a regularly updated index of web content. The system applies quality filters to prioritize authoritative and relevant sources, and customers can configure domain allow/block lists to further tailor result quality for their specific use case.
