Coresignal
Stands out: A real data API plus MCP at $49 Mini: this is enrichment infrastructure, not a Chrome overlay.
Watch out: Mini is 2,500 credits. Starter is $199 and Pro $499. Treating $49 as production volume will fail in week two.
Not the right fit for
- Recruiters who only want a LinkedIn Chrome finder
- Teams that need a sequencer
- Buyers who need ZoomInfo-the-UI
MixRank
Stands out: Six datasets under one contract, delivered into Snowflake, BigQuery, Redshift or Postgres as well as by API.
Watch out: No rate card and no self-serve API key. Expect a 45-minute call, a trial and a scoped quote before you see a number.
Not the right fit for
- SDRs who need a Chrome extension today
- Teams that want self-serve signup
