Cognism Review 2026: Pricing, Diamond Data & Verdict
Cognism built its reputation on phone-verified mobile numbers and GDPR-first compliance. With 440M+ contacts, a new AI-powered Sales Companion, and a leadership overhaul in 2025, here is what sales teams actually need to know.
What Cognism Actually Does
Cognism is a B2B sales intelligence platform. You search for contacts matching your ICP, export verified phone numbers and emails, and push them into your CRM or sales engagement tool. It is not an all-in-one platform with built-in email sequencing or dialers. It is a data layer that integrates with your existing Salesforce, HubSpot, Outreach, or Salesloft stack.
The company was founded in 2015 in London by James Isilay and Stjepan Buljat. It employs roughly 559 people and generated $83M in revenue in 2024 (up 30% YoY). In 2025, co-founder Isilay stepped down as CEO. Dominic Allon, the former CEO of Pipedrive, took over as permanent CEO alongside new CRO Chris Evans.
Diamond Data
Phone-verified mobile numbers. A human calls each number to confirm it reaches the right person. Claims 3x higher connect rates vs standard databases.
Sales Companion
AI-powered prospecting platform launched March 2025. Personalized dashboards, ICP fit checking, smart personas, and instant company research.
GDPR-First Compliance
ISO 27001, ISO 27701, SOC 2 Type II certified. Cross-checks against 13+ international Do Not Call lists. Registered with UK ICO.
What You Get
Diamond Data is the headline feature. Cognism's data team physically calls mobile numbers to verify they reach the correct person. They claim a 20% connection rate (7x the industry standard). Director-level and above data is refreshed every 30 days. You can also request "Diamonds on Demand" for on-demand verification of specific contacts.
Buyer Intent Data is powered by Bombora and only available on the Elevate plan. It shows account-level signals indicating which companies are actively researching topics relevant to your product.
Signal Data includes hiring trends, funding alerts, job changes, executive appointments, and technographic data tracking 20,000+ technologies.
CRM Enrichment fills missing fields in Salesforce and HubSpot. Supports on-demand enrichment via CSV uploads and API calls.
Browser Extension surfaces emails, mobile numbers, and GDPR-compliant data from corporate websites, LinkedIn, and your CRM.
What Cognism Costs
Cognism does not publish pricing. All figures below come from third-party reports and user disclosures.
| Grow (formerly Platinum) | Elevate (formerly Diamond) | |
|---|---|---|
| Platform Fee | ~$15,000/year | ~$25,000/year |
| Per User | ~$1,500/year | ~$2,500/year |
| Contact Access | Up to 25M | Up to 50M |
| Diamond Data | No | Yes |
| Intent Data (Bombora) | No | Yes |
| Technographics | No | Yes |
The 'Unlimited' Catch
Cognism markets 'unlimited' access, but a fair use policy caps individual record views at roughly 2,000 per user per month. Exports are limited to 25 records at a time without credits. A separate credit system exists for bulk operations and API usage.
Real-World Cost Ranges
Small team (1-3 users): $15,000-$18,000/year. Mid-sized team (~5 users): $22,500-$37,500/year. Enterprise (10+ users): $25,000-$100,000+/year. Annual commitment required. No monthly option. Discounts of 28-52% are reported depending on negotiation timing.
Where Cognism Wins
✓ Strengths
- European/EMEA data quality is genuinely best-in-class across multiple independent sources
- Phone-verified Diamond Data is a real, human-verified process (not algorithmic)
- GDPR compliance is architecturally embedded, not bolted on after the fact
- No per-contact credit anxiety that plagues ZoomInfo and Apollo users
- Customer support is consistently praised across every review platform
- $83M revenue and 30% YoY growth show real market traction
✗ Limitations
- US data is thinner than ZoomInfo for North American mid-market and niche industries
- Email accuracy reported at roughly 67%, lower than competitors
- APAC coverage is notably weak
- No built-in email sequences, dialer, or engagement workflows
- Pricing is opaque and premium ($15K+ floor), non-starter for small teams
- Annual commitment required with no monthly option
Cognism vs. ZoomInfo vs. Apollo
These are the three tools most sales teams evaluate together. Each serves a different buying profile.
| Dimension | Cognism | ZoomInfo | Apollo.io |
|---|---|---|---|
| Best for | EMEA-focused, phone-first SDR teams | US enterprise, large GTM orgs | Startups, SMBs, budget-conscious |
| Database size | 440M+ contacts, 100M+ companies | 600M+ contacts, 135M+ companies | 275M+ contacts |
| US data quality | Solid but thinner than ZoomInfo | Best-in-class for North America | Good US, variable globally |
| EU/EMEA data | Best-in-class | Improving but behind Cognism | Claims compliance, criticized for scraping |
| Phone verification | In-house human-verified (Diamond Data) | Community-verified | Real-time validation |
| GDPR compliance | Best-in-class, GDPR-first design | Robust but adds friction in EU | T&Cs give Apollo license to customer data |
| Pricing model | Flat annual fee + per user | Credit-based, can escalate fast | Transparent tiers, free plan exists |
| Starting price | ~$15K/year | ~$10K-30K+/year | Free tier, paid from ~$49/user/mo |
| Built-in engagement | No | Limited | Yes (email sequences, dialer) |
| Intent data | Bombora (Elevate only) | First-party + Bombora | Limited |
| Free plan | No (25-lead sample only) | No | Yes |
The GDPR Advantage (and Why It Matters)
If your team sells into Europe, this section is the reason Cognism exists on your shortlist.
Cognism processes data under GDPR Article 6.1(f) (legitimate interest). It is certified ISO 27001, ISO 27701, and SOC 2 Type II. It cross-checks against 13-15 international Do Not Call lists spanning the US, Canada, UK TPS/CTPS, Germany, France, Ireland, Spain, Portugal, Croatia, Sweden, Belgium, and Australia.
The platform is registered with the UK ICO and conducts regular compliance audits. Data storage generally stays within the EEA; transfers outside are protected by standard contractual clauses. Cognism also runs a "notified database" where data subjects are informed that Cognism holds their data so they can exercise opt-out rights.
By contrast, ZoomInfo has robust compliance but adds friction in EU contexts. Apollo claims GDPR compliance but has been criticized for scraping practices, and its T&Cs give Apollo a permanent license to use and share any data customers submit.
Why This Matters for Sales Leaders
A GDPR violation can cost up to 4% of global annual turnover. Cognism's compliance framework means your team can prospect in Europe without legal review on every outbound list. For teams selling cross-border, this is not a feature but a requirement.
What Cognism Connects To
CRMs: Salesforce (two-way sync), HubSpot, Microsoft Dynamics 365, Pipedrive, Bullhorn (recruiting).
Sales Engagement: Outreach and Salesloft (native integrations). The Chrome Extension also works within these platforms.
Other: LinkedIn Sales Navigator (via Chrome Extension), CSV upload/export, API access.
User-rated integration quality on G2: Salesforce 4.8/5, HubSpot CRM 4.9/5, LinkedIn Sales Navigator 5.0/5.
Integration Gap
Some enterprise users report integrations are not well built out beyond the core CRM connectors. No native Slack, Gong, or Clari integrations are available.
What Changed in 2025
Sales Companion (March 2025): The biggest product launch in company history. An AI-powered prospecting platform with personalized dashboards, ICP fit checking, smart personas, and instant company research. Available as a Chrome Extension and Web App.
Leadership Overhaul: Co-founder James Isilay stepped down as CEO. Pete Daffern served as interim CEO before Dominic Allon (ex-Pipedrive CEO) was appointed permanent CEO. Chris Evans joined as CRO.
Outreach Partnership (May 2025): Cognism was included in Outreach's expanded Data Partnership Ecosystem alongside ZoomInfo and SalesIntel.
Smart Personas (Q2-Q3 2025): AI feature helping GTM teams define target personas without manual playbooks.
Acquisitions to date: Kaspr (lead gen, May 2022), Ricochet, and Mailtastic.
Is Cognism Right for You?
Buy Cognism If...
Your team fits one or more of these profiles.
- Mid-market and enterprise sales teams selling into Europe/EMEA
- Phone-first outbound organizations (SDR/BDR teams that cold call heavily)
- Companies in regulated industries needing bulletproof GDPR compliance
- Teams willing to pay a premium for verified mobile numbers over raw volume
- Organizations already running Salesforce/HubSpot + Outreach/Salesloft that need a data layer
Skip Cognism If...
These teams will find better value elsewhere.
- Startups or small teams with budgets under $15K/year (look at Apollo)
- Purely US-focused sales organizations (ZoomInfo serves this better)
- Teams wanting an all-in-one prospecting + engagement platform (Apollo or Instantly)
- APAC-focused businesses (coverage is too thin)
- Marketing teams needing massive list builds (fair use policy and export limits constrain this)
Questions to Ask Before Signing
- What percentage of my target accounts are in the Cognism database? (Ask for a sample data test against your ICP.)
- How many Diamond Data records match my target titles and geographies?
- What is the fair use policy limit for my plan, and what happens when I hit it?
- Can I get a 90-day pilot before committing to an annual contract?
- What is the actual DNC scrubbing process for the countries I sell into?
- How does the credit system work for bulk operations and API access?
The CRO Report's Bottom Line
Cognism is not trying to be the cheapest or the most feature-rich. It occupies a specific niche: premium phone-verified data with best-in-class European coverage and compliance.
- If your team sells into EMEA or runs phone-heavy outbound, Cognism is a serious contender worth the premium
- If you are purely US-focused and budget-sensitive, ZoomInfo or Apollo will likely serve you better
- The 2025 leadership change and Sales Companion launch signal a company investing in product, not coasting
Run a data test before you buy. Ask Cognism to match against your target account list and compare the results to whatever you are using today. The data will tell you whether the premium is worth it.
