Head to head

Ocean.io vs ZoomInfo

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Ocean.io

Sales-quoted

ICP lookalike search that ranks companies from your closed-won deals. Paid plans are sales-quoted. Start free.

Where Ocean.io fits

  • B2B teams with a CRM full of closed-won deals
  • RevOps that want lookalikes pushed to Salesforce or HubSpot
  • Marketers who will send ranked accounts into Clay
  • GTM teams willing to start free, then talk to sales

ZoomInfo

Sales-quoted

Enterprise B2B contact graph with direct dials, org charts, technographics and intent. Quote-based, and overkill if you only need emails.

Where ZoomInfo fits

  • Talent teams where sales already pays for ZoomInfo
  • Desks that need reports-to lines and org charts
  • Account-based recruiting with intent data
  • Enterprise processes that already include the graph

Where they pull apart

Ocean.io

Stands out: It learns your ICP from won deals, then ranks every company in the market against that segment.

Watch out: There is no public paid rate card. Paid plans are a sales conversation after you start free.

Not the right fit for

  • Buyers who need a printed monthly credit pack
  • Teams with no won-deal history to seed a search

ZoomInfo

Stands out: The buying-committee graph and intent data, not just email lookup.

Watch out: Recruiter-only desks should price Wiza, ContactOut or Tomba first. This is an enterprise contract.

Not the right fit for

  • Recruiter-only buyers signing a new enterprise contract
  • Teams that only need email and mobile lookup
