One searchable directory

Search across startups, investors, founders, funding rounds, patents, and research, all enriched and cross-linked, so one query maps an entire market.
Always fresh
Agentic intelligence layer
Our agents read funding news, hiring signals, product launches, and filings around the clock, so every profile stays current without anyone touching a spreadsheet. Then the Lighthouse Engine traces a faint signal to a fully formed company profile: Palantir-grade identity resolution and graph-network technology that follows a bare domain to the live site, the company behind it, and the real people running it, every link independently verified. It's how we surface stealth startups before they ever announce.
