Standard and Pro plans each include 5 seats, with a credit allocation per seat (1 credit per revealed contact; re-viewing is free); extra credits are bought separately. CRM Enrichment is sold standalone or as an add-on. No free plan; the page offers a demo and a free data sample rather than a trial.Sales-led pricing; no public plan prices. The pricing page asks how many contacts you need per month and your company size before quoting, and offers free sign-up and competitor switch discounts.

Independent users who have used Cognism consistently point to European and UK data, and mobile numbers in particular, as its strength, with some finding it easier to deal with than ZoomInfo. The trade-offs are opaque pricing that some say rises after the first deal, thinner coverage outside Europe, and a minority who found its data poor or no better than cheaper tools. Nearly half of the Reddit mentions were promotional, including a large coordinated cluster praising Cognism for EU data as part of pitches for Crustdata and FullEnrich, a copy-pasted Cognism endorsement posted by two accounts, and plugs for ContactOut, Wiza and others, so this rests on about 20 independent opinions.

Users like

  • Users who run several providers single it out for UK and European data, where one team found it beat ZoomInfo's international data[1][2][3][4][5]
  • Mobile numbers are a highlight: users rate them above ZoomInfo and other tools, and one says it will source and phone-verify a missing number on request[1][2][3]
  • Easier to do business with than ZoomInfo: users cite better support, cheaper pricing and less painful sales and retention practices[1][2]

Users complain about

  • Pricing is opaque and can rise after signing: no prices on the site, a drastic change at renewal, and a low base price paired with a low export threshold that pushes buyers into extra credits[1][2]
  • Weaker outside Europe: one user found Apollo plus Lusha beat it on email coverage in North America and Europe, another says it is weak in the public sector, and one recruiter claimed in 2025 that it had pulled back from the US[1][2][3]
  • A minority found the data poor, rating it trash or worse than a cheaper tool, and a Dutch team found Lusha's database larger and more accurate[1][2][3][4]
  • More manual and less feature-rich than ZoomInfo, with some integration issues reported[1][2]

Independent users are largely negative: the most common reports are inaccurate data (guessed email patterns, wrong phone numbers, bounce rates near 20%), annual contracts that are hard to exit, and aggressive sales follow-up. A minority, mostly in 2023 to 2026 comments, rate the data as good enough to replace ZoomInfo at a fraction of the price, so data quality is contested rather than settled. The corpus shows no promotional seeding, but much of it is older r/sales discussion from 2022 and 2023.

Users like

  • Some users rate the data as comparable to ZoomInfo at a far lower price; one cut their annual spend by about $16k after switching[1][2]
  • Users who stick with it find it worth the money for finding mobile numbers, and the free trial plus referral credits let reps test it first[1][2]

Users complain about

  • Data accuracy is the main complaint: emails guessed from naming conventions, wrong phone numbers, and one two-year customer reporting 18 to 23% bounce rates[1][2][3][4][5]
  • Annual contracts with no cancellation; buyers describe being unable to exit and continuing to receive bills[1][2][3]
  • Aggressive sales outreach and weak support once the deal is signed; one person says the company cold called them about 20 times after removal requests[1][2][3][4]
  • Teams that tested it against ZoomInfo went back to ZoomInfo, citing more accurate and thorough data[1][2]
