Apollo.io vs Cognism
Side-by-side comparison for 2026. Which one is right for your team?
Apollo.io vs Cognism
Apollo wins for NA-focused teams on pricing and built-in outreach. Cognism wins for European data and phone-verified mobiles. Geography decides this one.
Apollo and Cognism both sell B2B contact data, but they built their products for different markets. Apollo is a Silicon Valley product optimized for North American prospecting with built-in sequencing that makes it an all-in-one outbound platform. Cognism is a London-based company that built its database around European data quality, GDPR compliance, and phone-verified mobile numbers.
The pricing difference is stark. Apollo offers a free tier with 10,000 records per month and paid plans starting at $49/user/month. Cognism does not publish pricing, but contracts typically start at $15,000-$25,000 per year with minimum seat requirements. For a 10-person SDR team, you are looking at $6,000/year on Apollo Professional versus $20,000+ on Cognism.
Data quality is where this comparison gets interesting. Cognism's Diamond Data feature provides phone-verified mobile numbers with a claimed 98% accuracy rate. Apollo's phone data is less reliable, especially for European contacts. If your outbound motion depends on cold calling, Cognism's phone data is worth the premium. If you run email-first outreach, Apollo's data quality is sufficient and the built-in sequencing saves you from buying a separate engagement tool.
The geographic split is the simplest decision framework. If more than 50% of your prospects are in Europe, Cognism is the better database. If more than 50% are in North America, Apollo gives you more value per dollar. Teams selling globally need to evaluate which region drives more revenue and optimize for that.

Detailed Breakdown
North American Data
Apollo has the edge for NA contacts with 270M+ profiles, strong email coverage, and decent phone numbers for US-based prospects. Cognism's NA data has improved but remains thinner outside of major metro areas. For US-focused SDR teams, Apollo covers more of the addressable market at a lower cost per contact.
European Data
Cognism wins clearly on European data. Built with GDPR compliance from day one, Cognism offers stronger coverage across the UK, DACH region, and Western Europe. The Diamond Data phone verification process adds significant value for European cold calling where mobile numbers are harder to find. Apollo's European data exists but has more gaps in coverage and accuracy.
Phone Data Quality
Cognism's Diamond Data is phone-verified by humans, resulting in a 98% connect rate on verified numbers. Apollo's phone data is sourced algorithmically and has a lower connect rate, typically 40-60% for direct dials. If cold calling is a primary channel, this gap alone can justify Cognism's premium.
Built-in Outreach
Apollo includes email sequencing, a built-in dialer, and LinkedIn task management at no extra cost. Cognism is a data platform only. You need a separate tool (Outreach, Salesloft, or similar) for engagement. Apollo's sequencing is not as powerful as dedicated platforms, but it eliminates $100-150/user/month in additional tool costs for most teams.
Pricing
Apollo wins on pricing by a wide margin. Free tier available, paid plans from $49/user/month, no annual minimums on lower tiers. Cognism starts at $15K+ annually with multi-seat minimums. The total cost difference for a 10-person team can be $15K-$20K per year, which buys a lot of additional tools or headcount.
GDPR Compliance
Cognism was built around GDPR. Every record includes consent status, do-not-call list checks, and processing basis documentation. Apollo complies with GDPR but does not provide the same depth of compliance metadata. For companies selling into the EU with strict legal teams, Cognism's compliance infrastructure reduces risk.
Integrations
Both integrate with Salesforce and HubSpot. Apollo's integration is tighter because it syncs engagement data alongside contact data. Cognism integrates as a data source only, which means cleaner separation of concerns but more tools to manage. Apollo also offers a more capable API for custom workflows.
Pricing Comparison
| Tool | Starting Price | Score |
|---|---|---|
| Apollo.io | Free / $49/mo | 8.8/10 |
| Cognism | Custom pricing | 8.1/10 |
Which Is Right for Your Stage?
Startups & SMBs
Apollo is the obvious choice for startups. The free tier gives you enough data to validate your ICP and run initial outreach without spending anything. The built-in sequencing means you do not need Outreach or Salesloft yet. Start on Apollo Free, upgrade to Basic ($49/mo) when you exhaust the free credits, and revisit your data strategy when you cross 20 reps.
Growth Stage
At growth stage, the decision depends on your market. US-focused teams should stay on Apollo and invest the savings in better tooling elsewhere. Teams selling into Europe should add Cognism for EU prospecting while keeping Apollo for NA. Running both databases in parallel is common at this stage and costs less than going all-in on either one for global coverage.
Enterprise
Enterprise teams often use both. Cognism for European outbound with phone-verified mobiles, Apollo for North American outbound with built-in engagement. If budget forces a single choice, pick based on where 60%+ of your revenue comes from. Negotiate Cognism's annual contracts aggressively since their list pricing has room for 20-30% discounts on multi-year deals.
Questions to Ask Before Choosing
- What percentage of your prospects are based in Europe vs. North America?
- Is cold calling a primary outbound channel, or do you lead with email?
- Do you already have a sales engagement platform, or do you need one included?
- What is your per-seat budget for data tools?
- Does your legal team require GDPR compliance documentation for every contact record?
- How many new contacts per month does each SDR need?

Frequently Asked Questions
Is Apollo accurate enough for enterprise prospecting?
For North American contacts, Apollo's accuracy is comparable to ZoomInfo for most segments. Email accuracy runs 85-90%. Phone accuracy is lower at 40-60% for direct dials. Enterprise accounts with public information are well-covered. Niche industries and small companies have more gaps. If you need guaranteed accuracy on every record, ZoomInfo or Cognism's verified data is worth the premium.
Can Cognism replace Apollo entirely?
Only if you have a separate engagement platform. Cognism is data-only with no built-in sequencing. You need Outreach, Salesloft, or similar for outreach. If you already pay for an engagement tool, Cognism can be your sole data provider, but you will pay more for less NA coverage.
Which tool has better intent data?
Neither is strong on intent. Apollo offers basic intent signals through Bombora integration on higher tiers. Cognism partners with Bombora as well. For serious intent data, you need a dedicated platform like 6sense or Bombora direct. Do not choose between Apollo and Cognism based on intent features.
How do the Chrome extensions compare?
Both offer LinkedIn Chrome extensions for finding contact data while browsing profiles. Apollo's extension also lets you add prospects directly to sequences. Cognism's extension surfaces Diamond Data phone numbers. Apollo's extension does more, Cognism's extension provides higher-quality phone data.
