Harmonic is a private market intelligence platform built for investors and go-to-market teams. It maintains a database of over 35 million companies and 195 million professional profiles, sourced from legal filings and dozens of public data sources. The platform updates its records on a cohort-based cycle, with priority companies refreshed daily.

You can search for companies using granular filters that cover sector, stage, geography, headcount growth, founder background, and funding activity. The AI search agent, called Scout, accepts natural-language queries and returns ranked results based on your investment thesis. Scout can also draft outreach messages and generate research reports that combine proprietary data with web sources.

Harmonic offers a Chrome extension for contextual lookups, an API for enriching CRM data, bulk data delivery via S3 or BigQuery or Snowflake, and integrations with Zapier and n8n.
