Apollo.io vs Cognism: Database, Phone Data, GDPR Compliance, and Pricing Compared

Apollo.io and Cognism target overlapping markets but solve different problems. Apollo is a budget-friendly, all-in-one outbound platform built for US-centric SMB teams. Cognism is a premium data provider specializing in phone-verified mobile numbers and GDPR-compliant European data. Choosing between them depends on your geographic focus, phone outreach requirements, and compliance obligations.

The Phone Data Difference

This is the critical differentiator. Apollo includes phone numbers on paid plans, but these are algorithmically sourced — meaning they are pulled from public directories, social profiles, and pattern matching. Independent reports suggest Apollo’s mobile number accuracy runs between 30-45%.

Cognism uses Diamond Data — phone numbers that have been manually verified by human researchers who actually called the number to confirm it reaches the intended person. This human verification layer pushes Cognism’s mobile accuracy above 80%, making it significantly more reliable for SDR teams that rely on cold calling.

For teams where phone outreach is a primary channel, this accuracy gap translates directly into daily connect rates and pipeline generation.

GDPR and Compliance

This matters for any team selling into European markets:

Apollo.io provides basic compliance features — you can check a global Do-Not-Call (DNC) list and handle opt-out requests. However, Apollo’s data collection methods have faced scrutiny regarding GDPR consent. The platform sources data through web scraping and aggregation, which may not satisfy strict GDPR interpretations of “legitimate interest.”

Cognism was built compliance-first for the European market. It maintains a comprehensive, regularly updated DNC database covering the UK, Germany, France, and other EU markets. Cognism’s data processing agreements (DPAs) and privacy documentation are designed to meet enterprise legal team requirements — a critical factor for mid-market and enterprise companies where legal review is mandatory before vendor onboarding.

Pricing Comparison

Aspect	Apollo.io	Cognism
Pricing model	Per-user, transparent	Custom quotes, annual contracts
Entry price	$49/user/month	~$1,000+/month (estimated)
Free plan	✅ Yes (generous)	❌ No
Phone credit costs	$0.65/number (Basic plan)	Bundled in subscription
Contract terms	Monthly or annual	Annual minimum

Apollo wins definitively on price accessibility. Cognism wins on data quality for phone-heavy, EMEA-focused teams.

When Each Tool Wins

Choose Apollo.io if:

• Your team primarily targets US-based accounts.
• Email is your primary outreach channel (phone is secondary).
• You need an all-in-one platform under $100/user/month.
• You want a free plan to test before committing.

Choose Cognism if:

• You sell into European markets and need GDPR compliance.
• Cold calling is a primary pipeline generation channel.
• Phone number accuracy directly impacts your SDR team’s daily productivity.
• Your company’s legal team requires vendor DPAs and compliance documentation.

Neither Tool Solves the Timing Problem

Both Apollo and Cognism give you contact data — emails, phone numbers, company information. Neither tells you exactly when a specific person is actively evaluating solutions like yours.

Typpout solves the timing problem. AI agents monitor real-time social signals — Reddit threads, LinkedIn posts, X discussions — to identify the exact moment a buyer asks for product recommendations. The system enriches contacts through multi-provider waterfalls (matching Cognism-level accuracy), drafts contextual outreach, and books meetings autonomously.
