What Harmonic is

Harmonic is a startup intelligence database for following 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 gathers information from legal filings and dozens of public sources, then refreshes it regularly. Scout lets users ask about startups or set up scheduled AI agents to find, evaluate, and track companies, people, deals, and markets.

Network Mapping associates LinkedIn connections, email and calendar events, and CRM engagements with companies and operators in Harmonic’s database. The maker presents the product for venture capital, growth capital, corporate innovation, and go-to-market prospect discovery. Users can access data through REST or GraphQL APIs, MCP connectivity, or bulk delivery through S3, BigQuery, or Snowflake. Integrations include Slack alerts, Google accounts, Affinity, LinkedIn connections, Polytomic, and Zapier. Console, API access, and Bulk Data pricing is available by request. Scout includes up to $750 in monthly credits per user, and the Scout API has a $250 free credit allowance. Harmonic states that it is ISO 27001 certified and SOC 2 Type II compliant.
