What Harmonic is
Harmonic is a startup database for tracking companies and people as they hire, raise funding, launch products or change direction. Its Console and Bulk Data offerings list 40 million companies, 200 million people and 250 thousand investors. Harmonic says it draws on legal filings and public sources, with regular refreshes. Scout lets users ask about startups or schedule AI agents to find, evaluate and track companies, people, deals and markets. Network Mapping links LinkedIn connections, email and calendar events, and CRM engagements to companies and operators in the database.
The maker presents Harmonic for venture capital, growth capital, corporate innovation and go-to-market prospect discovery. Native integrations include Slack alerts, Google accounts, Affinity and LinkedIn connections; third-party options include Polytomic and Zapier. Access includes REST or GraphQL APIs, MCP connectivity and bulk data delivery through S3, BigQuery or Snowflake. Console, API and Bulk Data pricing is available on request. Harmonic says each user can use up to $750 of Scout credits per month for free, and the Scout API has a $250 free credit allowance. It lists ISO 27001 certification and SOC 2 Type II compliance. Network Mapping data is isolated to each firm and encrypted at rest with row-level security; only email subject lines and meeting participants are surfaced.
