Deep Dive: Clearbit
What They're Selling
Real-time data enrichment that automatically appends company and contact data to every record in your CRM, marketing automation, and product analytics. Now part of HubSpot.
What It Actually Costs
Free for HubSpot users (basic enrichment included in HubSpot plans). Standalone Clearbit pricing is custom, typically $12-36K/year based on enrichment volume. Reveal (website visitor identification) is a separate product with its own pricing. The HubSpot acquisition has made Clearbit's enrichment increasingly bundled into HubSpot's platform.
What Users Say
Marketing ops teams value Clearbit's invisible, automatic enrichment. Data flows in without anyone doing manual lookups. The firmographic and technographic data quality is strong for North American companies. Complaints: phone number coverage is limited (not a prospecting database), European data is thinner than Cognism's, and the HubSpot acquisition has created uncertainty about standalone availability.
Pros
- Real-time automatic enrichment without manual lookups
- Strong firmographic and technographic data
- Free for HubSpot users (basic enrichment)
- Reveal identifies anonymous website visitors by company
Cons
- Limited phone number data compared to prospecting tools
- European data coverage is thinner than Cognism's
- HubSpot acquisition creates uncertainty for non-HubSpot users
- Not a prospecting database, can't search for new contacts
Deep Dive: Cognism
What They're Selling
B2B prospecting database with the strongest European coverage and phone-verified mobile numbers, built for outbound teams selling into EMEA markets.
What It Actually Costs
Pricing is custom, starting around $25K/year for mid-market. Full platform access with Diamond Data (phone-verified mobiles) runs $35-60K/year. Implementation is straightforward (2-4 weeks). The premium over competitors is justified by European phone data quality.
What Users Say
European sales teams consider Cognism's phone data essential for EMEA prospecting. The phone-verified mobile numbers are its core differentiator: you get numbers that people pick up. Complaints: North American data doesn't match ZoomInfo's depth, the platform is less feature-rich than Apollo, and pricing is premium for what's primarily a data tool.
Pros
- Best-in-class European phone-verified mobile numbers
- Strong GDPR compliance with Do Not Call list checking
- Diamond Data provides human-verified direct dials
- Good coverage across UK, DACH, and Nordics
Cons
- North American data coverage trails ZoomInfo and Apollo
- No email sequences, dialer, or pipeline management
- Premium pricing for what's primarily a data tool
- Smaller database overall than Apollo or ZoomInfo

Frequently Asked Questions
Does Clearbit have phone numbers like Cognism?
Clearbit provides some phone data but it's not a phone-first tool. Cognism's Diamond Data provides human-verified mobile numbers, especially in Europe. If phone prospecting is a primary channel, Cognism is the better data source for direct dials.
Can Cognism do real-time enrichment like Clearbit?
Cognism has some enrichment capabilities but it's primarily a searchable database, not a real-time enrichment API. Clearbit automatically enriches records as they enter your CRM or marketing tools. For automated, invisible enrichment, Clearbit's approach is fundamentally different.
What happened with Clearbit and HubSpot?
HubSpot acquired Clearbit in 2023. Clearbit's enrichment data is being integrated into HubSpot's platform, with free enrichment for HubSpot users. Standalone Clearbit is still available but the long-term direction favors HubSpot integration. Non-HubSpot users should monitor whether standalone access remains available.
