Harmonic operates a startup discovery engine that maintains 35 million-plus companies and 195 million-plus professional profiles, updated daily via an always-on data pipeline that scours legal filings, web sources, and social signals. The platform is used by more than 100 venture capital and go-to-market teams—including a16z, Accel, Floodgate, Pear VC, NEA, and Google Ventures—to find, analyze, and monitor startups before they appear in traditional databases.
The company's flagship AI agent, Scout, answers natural-language questions about private markets, generates market maps, evaluates momentum, drafts outreach, and understands investment intent. Harmonic also offers a Chrome extension, REST and GraphQL APIs, and bulk data warehouse exports. Founded in 2020 and headquartered in San Francisco, Harmonic has raised $30 million across a $7 million seed round and a $23 million Series A led by SoZo Ventures.
