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.
