The startup database tuned for freshness: early rounds, stealth companies and hiring jumps, often days ahead of the bigger indexes, with the founders already attached.
What is
Harmonic
Harmonic is a startup database built on one bet: the interesting moment is before everyone knows. It tracks 35 million companies and 195 million people, and tunes the whole machine for freshness, early rounds, stealth companies still quiet on their own website, and the hiring jumps that give a raise away before the press release. For a funding workflow that freshness is the entire value. The outreach window after a round is measured in days, and a feed that runs days ahead of the big indexes hands you the window instead of the aftermath. The people layer is the second act. A round arriving with the founders, the new executives and their histories attached means the workflow can pick the right person and write the opener in the same pass, with no separate people search. The trade is opacity and tilt. Pricing lives behind a sales call, and the coverage leans hard toward venture-backed tech, so it shines exactly where your market overlaps with that world and thins out where it does not.
Integrations and the modern GTM stack
Harmonic hands its data over in three ways:
API | Enrichment and discovery on demand, with financing and investor data as an add-on and CRM sync available on top. |
Bulk data | Weekly-refreshed drops into S3, BigQuery or Snowflake, for teams that keep their data under their own roof. |
Console and watchlists | The human surface: saved searches and watchlists whose changes flow out as the signals a workflow acts on. |
Pro’s
Freshness is the product: early rounds, stealth companies and hiring jumps surface here days before the bigger indexes write them down.
The people layer runs deep, 195 million records, so the round arrives with the founders and operators already attached.
Watchlists turn a market into a feed: define who you care about once, and the changes come to you.
Bulk delivery straight into a warehouse suits teams that want the data under their own roof.
The AI search agent answers questions a filter interface cannot express.
Cons
No public pricing: every plan starts with a sales conversation, and budgeting starts with a guess.
Coverage tilts to venture-backed tech, so an old-economy market will find it thin.
Financing data on the API is an add-on rather than the default.
Younger than the incumbent indexes, and some markets show the shorter history.
