Where Harmonic is strong — and where we differ

Choosing an alternative should start with what the incumbent does well.

Where Harmonic is strong

  • Early discovery of newly formed startups and founders, built for venture sourcing.
  • People- and team-centric signals that help spot companies before they raise.
  • A sourcing workflow designed around how VC teams build pipelines.

Pick Harmonic if your main job is finding the earliest-stage startups before anyone else, from founder and team signals.

Where MarketPrior differs

  • We start from primary public records and cite each finding, rather than from inferred people signals.
  • Diligence depth on a named company: sanctions, litigation, registry history and officer changes alongside upside signals.
  • Public-record triggers such as Form D filings, contract awards and officer changes.
  • Pay per report or a monthly plan; API and MCP access for your own agents.

What we don't have

The honest gaps

MarketPrior reads public records only. That keeps every finding checkable — and means some things are out of scope. See every source on the public-record data sources page.

  • Less emphasis on pre-launch stealth discovery from talent and social signals.
  • No proprietary people graph built from professional-network data.
