Sales intelligence platforms should help your GTM teams connect with real buyers, fast. Cognism claims to fit the bill, especially in the EU. But user reviews tell a more mixed story: data gaps, limited support, and inflexible plans.
If you’re evaluating top B2B go-to-market data providers, it’s important to get the full picture of how Cognism compares to the rest. Here are some key questions to answer, based on real user and customer reviews from across the web.
Cognism Data Quality and Accuracy Reviews
Lower-ranking Cognism reviews highlight problems with outdated records, missing mobile numbers, and unreliable data. These gaps leave sellers second-guessing their outreach and wasting precious time. "Terrible Data. They send you a list that is hand curated for your testing throwing you off ... Anyhow it’s terrible data quality, go with Zoominfo every day of the week" — G2 Review
"What do you dislike about Cognism?: The loss of the verification service, the lack of mobiles or direct numbers, the dated nature of the data" — G2 Review
ZoomInfo’s proprietary B2B identity graph and rigorous verification processes ensure you connect with the right buyers, with direct dials, verified emails, and the freshest company insights. Our commitment to accuracy means your pipeline is built on trust.
Cognism Platform User Feedback
Sales teams need tools that are intuitive, fast, and reliable. Cognism reviews can describe the opposite: unintuitive workflows, slow load times, and features that feel incomplete.
“You can't filter out companies that are currently in your CRM so that can be frustrating. Often the phone numbers are wrong and when pulling people into the CRM it tends to duplicate - you can turn this off but then you can’t pull new people / companies in at all … Also it's very expensive compared to other providers.” — G2 Review
ZoomInfo’s platform is built for speed and usability, with seamless CRM and marketing automation integrations, intuitive workflows, and reliable performance that scales with your team.
Cognism Pricing, Contracts and Credits Reviews
Customers often describe Cognism’s pricing as opaque, inflexible, and burdensome. Instead of scaling with your business, Cognism reviews report the model can feel restrictive and costly.
"I don't like anything about Cognism. The platform is very basic and expensive." — G2 Review
ZoomInfo offers flexible packaging that grows with you, and clear value that matches your investment.
Cognism GDPR and Compliance Concerns
Some Cognism customers have raised concerns about how Cognism acquires and manages data, and accusations of unwanted calls and questionable practices are apparent across Cognism reviews.
"Obtaining private data in unknown manner and then sharing it to 3rd parties … Businesses should carefully evaluate the legitimacy of this company and its practices." — TrustPilot Review
ZoomInfo leads the industry in compliance. With privacy-by-design, GDPR/CCPA readiness, consent-based collection, and ongoing third-party audits, you can trust that your go-to-market motions are built on a safe, compliant foundation.
Cognism Customer Support and Experience Reviews
From onboarding to day-to-day support, Cognism reviews show evidence of an underwhelming experience, ranging from slow responses to a lack of training and enablement. For teams investing heavily in sales intelligence, that lack of partnership is a dealbreaker.
"I've found the data to be weak and support to be non-existent." — G2 Review
With VIP onboarding, dedicated customer success managers, and 24/7 support, ZoomInfo ensures you see value quickly and sustain results for the long term.
Is Cognism Worth It?
The collective feedback in Cognism reviews highlights significant concerns regarding data quality, platform usability, pricing transparency, compliance practices, and customer support.
While Cognism aims to be a leading B2B data provider, particularly in the EU, the recurring issues reported by users suggest that potential customers should carefully weigh these factors against their go-to-market needs.
