What is Harmonic
Harmonic is a B2B data enrichment platform designed for sales teams, RevOps, and data-driven companies who need high-quality contact and company data without the overhead of expensive enterprise subscriptions. It provides contact database with 100M+ B2B contacts and 90%+ email accuracy, firmographic enrichment including technographics, funding history, and employee trends, API-first architecture enabling programmatic access for enrichment workflows, usage-based pricing paying only for records accessed not seat licenses, and CRM integration auto-enriching Salesforce and HubSpot records. People use Harmonic because it prioritizes data quality over quantity (90%+ accuracy vs 60-70% for cheaper alternatives), offers flexible usage pricing instead of per-seat licensing, and provides deep firmographics not just basic contact info.

It fits smoothly into your tech stack by integrating with Salesforce, HubSpot, Clay, and custom applications via REST API.
