Where they pull apart

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

SignalBase

Stands out: Funding, hiring, job-change, and M&A signals with the source URL attached, plus MCP for agents.

Watch out: Prices are in euros. There is no USD rate card. Custom starts above 3 seats or for white-label.

Not the right fit for

SDR teams buying emails and mobiles for cold email
Buyers who need a US-dollar rate card
