Where they pull apart

6sense

Stands out: Predictive account scores plus a Sales Copilot that recommends actions, summarizes accounts and drafts messages.

Watch out: No public price. Emails, phones and exports need separate data credits, and predictive AI is a separate package.

Not the right fit for

SMBs that need a published per-seat checkout
Recruiters looking for a candidate sourcing database

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
