Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cognism

  • United States coverage is behind ZoomInfo, and the gap shows most in mid-market American accounts where record density thins out.
  • The commercial model combines an annual platform fee, per-seat licences and credit allowances, so a quoted seat price consistently understates the total.
  • Diamond Data verified mobiles are a subset of the wider database rather than the whole of it, and the subset available for your target market should be tested before signing.
  • There is no free tier and no monthly rolling contract, so evaluating properly means committing to a year or relying on a short trial with limited data.
  • Coverage density varies sharply by country, with the United Kingdom strong and DACH and the Nordics noticeably thinner, which matters if your expansion market is the weak one.

ZoomInfo

  • ZoomInfo prices on a credit-consumption model rather than flat seats: each contact/company export costs one credit, packages include a fixed number of monthly credits (one named package includes 75K credits), and integrations require a minimum bulk credit purchase to install, per the vendor's own pricing page.

Answered from the vendors’ own pages

Cognism: Can a European company use it lawfully?

It notifies contacts held in its EU and UK database and screens do-not-call registers, which supports a legitimate interest basis. The balancing test, record keeping and handling of objections remain your obligation, not the obligation of the vendor.

Cognism: How does it compare with ZoomInfo on coverage?

ZoomInfo is stronger in the United States, Cognism is generally stronger on European mobile numbers. That, rather than feature lists, is what most head-to-head evaluations come down to.

Cognism: Can we buy a single seat monthly?

No. Contracts are annual with a platform fee, which makes a genuine pilot harder than with credit-based self-serve vendors.
