Exa is building a search engine from scratch to serve every AI agent. We build massive-scale infrastructure to crawl the web train state-of-the-art embedding models to process it and design super high performant vector databases in rust to search over it. If you like compute we also own a $5M H200 GPU cluster (and soon 5xing that) and regularly spin up batchjobs with tens of thousands of machines.
