Apollo vs Cognism
All-in-one platform with 275M+ contacts vs European data specialist with phone-verified numbers.
Apollo and Cognism are the two B2B data tools most often compared in 2026 procurement bake-offs, and they win different deals. Apollo is an all-in-one sales platform: 275M+ contacts, sequences, a dialer, and basic CRM features, starting at $59/user/month and topping out at $149/user/month on Organization. Cognism is a data specialist with GDPR-compliant coverage, particularly deep in European markets, and Diamond Data, a manually phone-verified mobile dataset. Cognism contracts are typically annual and land between $15,000 and $35,000/year. Apollo wins on price and all-in-one workflow. Cognism wins on European coverage, phone connect rates, and compliance.
This page compares them on real seat economics, data quality (especially mobile match rates), GDPR posture, and the workflows where each tool actually delivers ROI. Most teams that run both do it for one specific reason: Cognism for European phone data, Apollo for US engagement and outbound execution.
The Bottom Line
Apollo wins for US-focused teams under 50 reps that want data plus engagement in one platform at a price point Cognism cannot match. The combination of 275M contacts, sequences, dialer, and free-tier evaluation makes Apollo the easiest tool to deploy quickly. Cognism wins for European teams, regulated industries, and any motion where verified mobile connect rates drive revenue. Its Diamond Data mobiles and GDPR compliance are advantages Apollo cannot match. The hybrid stack (Apollo for engagement plus Cognism for European data, exported into Apollo sequences) is the standard pattern for global revenue teams in 2026.

Data Coverage: 275M Apollo Contacts vs Cognism's European Edge
Apollo's 275M+ contact database is the broadest in B2B SaaS, with particular strength in North American mid-market and enterprise. Email match rates run 85 to 95 percent on VP-and-above roles at companies with 50+ employees. Mobile match drops to 60 to 75 percent depending on the role. Coverage in Asia-Pacific and Latin America is thinner.
Cognism does not match Apollo's raw size, but it dominates European coverage. UK, Germany, France, and Nordics are markets Cognism was built for, and match rates there run 30 to 50 percent higher than Apollo's. The Diamond Data subset (manually verified mobiles) is what European outbound teams pay for: connect rates two to three times higher than aggregated data, which transforms dial-heavy motions. For US data, Apollo's breadth wins. For European data, Cognism's depth and compliance win.
Pricing: Per-Seat List vs Annual Enterprise Contract
Apollo's pricing is transparent and per-seat: free tier, Basic at $59, Professional at $99, Organization at $149. No minimum contract beyond the 3-seat Organization tier. Teams can start on the free tier, upgrade one seat at a time, and cancel monthly. This removes procurement friction and makes Apollo the default starter for SMB and mid-market teams.
Cognism does not publish list prices and sells annual contracts. A 10-rep team typically lands between $15,000 and $30,000/year, with Diamond Data and Enterprise tiers pushing the upper end. Annual commits mean procurement involvement, longer sales cycles, and less flexibility, but the flat-rate model becomes attractive for high-volume teams that would burn through Apollo credits on usage-based plans.
Workflow: Engagement Platform vs Data Specialist
Apollo is an end-to-end outbound platform: search, enrichment, sequences, dialer, basic CRM, and integrations with Salesforce, HubSpot, Outreach, and Salesloft. A rep can find a prospect, pull their email and mobile, drop them into a multi-touch sequence, and start calling without leaving the tool. For teams that want one platform to run outbound, Apollo's workflow density is hard to match.
Cognism is a data specialist that integrates with the engagement layer rather than replacing it. Verified contact data pushes into Salesforce or HubSpot for sequencer enrollment in Outreach, Salesloft, or Apollo. Cognism does not run cadences itself. This means Cognism slots cleanly into existing outbound stacks but requires a separate engagement tool. The trade-off: focused data quality versus integrated workflow.
Real Stack Pattern: When Teams Run Both
The most common 2026 setup at global revenue teams uses both. Cognism is the data layer for European prospects, where its GDPR posture and Diamond Data mobiles are required. Apollo is the data layer for US prospects and the engagement layer for both regions. Workflow: SDRs identify accounts in Sales Navigator, pull European contact data from Cognism and US contact data from Apollo, sync everything into Salesforce or HubSpot, and run sequences inside Apollo. This setup runs roughly $400 to $600 per rep per month all-in, more than either tool alone but still cheaper than ZoomInfo plus Outreach.
How to Choose
Start with geography and total addressable market. If your ICP is 70 percent or more US-based, Apollo's database is broader, its tooling is more complete, and it costs significantly less per seat. Validate Apollo's match rate against your top 100 target accounts on the free tier before committing.
If you sell into the UK, DACH region, France, Nordics, or other European markets, Cognism's coverage is materially better. Apollo's European data exists but thins out below the C-suite and lags in update frequency. For ABM motions on European enterprise accounts, Cognism finds decision-makers Apollo misses.
Phone-driven motions tilt toward Cognism. Diamond Data's verified mobiles produce connect rates two to three times higher than aggregated phone numbers. If your team makes 50+ calls per rep per day, Cognism's per-dial economics usually beat Apollo's despite the higher entry price.
Budget and team size matter. Apollo's free tier and $59/seat starter mean a 5-rep team can start for under $300/month. Cognism's annual contract and minimum seat counts mean a similar team is looking at $15,000+ committed before the first call. For SMB and early mid-market teams, Apollo is the easier first buy. For 30+ rep teams with European customers and dedicated procurement, Cognism's contract structure becomes manageable.
Frequently Asked Questions
How does Apollo's European data compare to Cognism's?
Apollo's European data exists but is thinner and less accurate than its US data. Cognism was built for European markets from day one and has materially better coverage in the UK, Germany, France, and Nordics. For enterprise contacts at major European companies, Cognism's match rates run 30 to 50 percent higher than Apollo's. For US data, the gap reverses: Apollo's 275M+ contact database is broader and refreshed more aggressively.
Is Apollo's free tier enough to evaluate the platform?
Yes. Apollo's free tier includes basic sequences, contact exports each month (limits vary by plan changes), and the full search interface. It is enough to test data quality against your ICP, run early outbound, and decide if the platform fits. Cognism offers demos and trials but no free tier, so Apollo is the easier platform to evaluate without a sales conversation. Most teams kick the tires on Apollo first and bring Cognism in only when European coverage becomes the bottleneck.
Which tool has better phone data and connect rates?
Cognism, specifically because of Diamond Data, its program of manually phone-verified mobile numbers. Each Diamond mobile has been called and confirmed to reach the named person, producing connect rates 2 to 3 times higher than aggregated phone data. Apollo's phone data is aggregated from multiple sources without phone-level verification, which is fine for many use cases but cannot match Diamond's per-dial economics. If outbound dialing is your primary motion, Cognism's phone data is worth the premium.
What does Apollo cost compared to Cognism in 2026?
Apollo offers a free tier and four paid plans: Basic at $59/user/month, Professional at $99/user/month, Organization at $149/user/month (3-seat minimum), and a custom Enterprise tier. Cognism does not publish list prices and sells annual contracts that typically land between $15,000 and $35,000/year depending on team size, Diamond Data inclusion, and regional scope. For a 10-rep team, Apollo Organization runs roughly $18,000/year all-in versus $20,000 to $30,000 for Cognism. Apollo is cheaper at every comparable scale.
Is Cognism GDPR-compliant and Apollo not?
Both tools claim GDPR compliance, but Cognism's posture is materially stronger. Cognism was built around GDPR from inception: lawful basis, registered opt-out lists, EU data residency, and data subject access request workflows are platform features, not afterthoughts. Apollo is GDPR-compliant as a data processor but its European data sources are weaker, which raises practical compliance questions for outbound to EU prospects. For regulated industries and European outbound, Cognism's compliance story passes legal review faster.
Can I use both Apollo and Cognism together?
Yes, and many global teams do. The standard pattern is Cognism for European contact data (especially Diamond Data mobiles for cold calling), exported into Apollo for sequencing and engagement on the US side. Cognism handles the data layer where compliance and verified mobiles matter; Apollo handles the workflow layer where sequenced multi-channel outreach drives volume. Total cost is higher than either tool alone but the combined coverage is hard to beat for global revenue teams.
Which is better for an SDR team running outbound at scale?
Apollo, for US-focused SDR teams. SDRs need volume, sequenced outreach, and integrated dialer, and Apollo delivers all three at one price point with no procurement friction. Cognism is better for an enterprise AE motion or an EU-focused outbound team where Diamond Data mobiles drive connects. The dividing line is geography and call volume: high-volume US SDRs default to Apollo; named-account or EU-focused teams default to Cognism.
