Questions
Clearbit vs People Data Labs: what is the difference?
Clearbit now works inside HubSpot and enriches CRM records there. People Data Labs sells person data directly, through APIs, bulk data and data licensing, with a free plan that excludes contact data. The table above links both vendors' own pages.
What are Clearbit enrichment alternatives for teams that do not use HubSpot?
Vendors that sell enrichment on its own include People Data Labs (APIs and bulk data), Apollo (API on Custom plans), ZoomInfo and Coresignal. The Autobound Signal API is a different kind of enrichment: it adds dated events to a domain or contact, not firmographic fields.
Are there cheaper alternatives to Clearbit for mid-market lead scoring?
The table shows each vendor's published pricing model with its source, so you can compare. For scoring on timing, the Signal API is priced per credit: 2 credits per result, nothing for an empty result, and 1,000 free credits to test.
