Cognism
Pros
- Phone-verified "Diamond" mobiles deliver markedly higher connect rates than most rivals.
- Compliance-first, with GDPR treated as an engineering concern and notified-jurisdiction screening across 15+ countries.
- Strongest UK & EMEA coverage in the category; reps can build usable lists on day one.
- Ease of use is the most-praised aspect across G2 (4.5/5) and Capterra (4.7/5) reviews.
Cons
- Pricing is sales-led and opaque, with annual-only contracts, prohibitive for small teams.
- US, Canada and APAC coverage is weaker than its UK/EMEA core.
- Diamond verification covers only a subset of records; "accuracy" claims apply to that subset, not the whole database.
- A US right-of-publicity class action (Kis v. Cognism) settled in 2025 over contact data shown to free-trial users; Cognism denied wrongdoing.
ZoomInfo
Pros
- The deepest US database in the category, with 500M+ profiles claimed, org charts, scoops and news signals.
- A genuinely all-in-one platform, bundling intent data, website visitor ID (WebSights), enrichment and technographics together.
- Precise, powerful search and filtering that experienced teams rate highly (G2 4.5/5 from 9,000+ reviews).
- Strong CRM and workflow integrations.
Cons
- Opaque, five-figure pricing, with Vendr data putting the median deal near $33,500/yr and all-in costs commonly $30k–$60k.
- Rigid multi-year contracts and 60-day auto-renewal terms are the most common complaint, with state-AG complaints on record.
- Data accuracy decays outside the US and for older records; international coverage is a paid add-on.
- Two US right-of-publicity cases ($29.55M Ramos settlement; Martinez allowed to proceed) reflect ongoing data-subject backlash over being listed.
