Could you build this?
No Exa's value is a proprietary search index of billions of documents plus a custom embedding model, not the API layer. Matching it requires web-scale crawling, indexing infrastructure, and model training.
What it would actually take: A comparable product needs a large crawl and index covering billions of web pages, ecommerce listings, and local business records, plus a trained embedding model. The infrastructure is distributed storage, vector indexing at scale, and continuous freshness pipelines. That needs a search infrastructure team and substantial capital for compute and data.
