In-Depth
ZoomInfo
Enterprise B2B contact and company data platform. ZoomInfo is the data standard RevOps teams at large companies run on, but the cost, contract structure, and aggressive sales tactics make it a love-hate relationship.
Alternative
Cognism
The strongest B2B data provider for European markets. Cognism built its reputation on GDPR-compliant data collection and phone-verified mobile numbers (Diamond Data). RevOps teams selling into the UK, DACH, or Nordics get contacts that ZoomInfo and Apollo do not cover.
Alternative
Lusha
The simplest enrichment tool on the market. Install the Chrome extension, visit a LinkedIn profile, and get contact info in seconds. The free tier gives you 5 credits/month. For individual contributors and small teams that need quick lookups without deploying a full platform, Lusha stays out of the way.
AlternativePeople Data Labs
Developer-first B2B data API with 1.5B+ person records. People Data Labs sells raw data access through APIs, not a platform. RevOps teams with engineering support use it to build custom enrichment pipelines. The coverage is broad, and the per-record pricing is competitive for bulk operations.
How to Choose
- Clearbit was the API darling. Now it's Breeze, locked inside HubSpot. If you're not on HubSpot (or you want more than real-time enrichment), Verum offers batch enrichment from 50+ sources. Different model, often better results for bulk operations.
- Apollo.io gives you Clearbit-style enrichment plus a contact database and engagement platform for $49/user/month. The enrichment depth is comparable for most fields, and you get outbound tools included.
- ZoomInfo is the enterprise-grade enrichment upgrade. Deeper data, intent signals, and workflow automation. The cost difference is significant, but so is the coverage gap on VP+ contacts.
- Cognism is the pick for European markets. GDPR-compliant data collection and phone-verified mobiles that Clearbit never covered well. If your prospects are in the UK or DACH, Cognism fills the gap.
- Lusha is the lightweight alternative. Chrome extension for instant lookups, free tier to test, and no platform to implement. Less depth than Clearbit's company data, but faster time to value for individual reps.
- People Data Labs is the developer-first option. If you built custom integrations on Clearbit's API and need a raw data replacement, PDL's 1.5B+ person records at per-record pricing is the closest architectural match.
