Harmonic

Harmonic is a startup-discovery database that tracks companies and founders — including stealth and pre-raise teams — and exposes the data through search, saved views, and an API. Funds wire it into their CRM so new companies matching a thesis arrive as dealflow instead of being hunted manually.
