How to choose
- Coverage in your actual market: test UK, EU and US records separately
- Mobile numbers vs emails: few tools are strong at both
- Pricing model: seats, credits or pay per found result

Frequently asked questions
What is the most accurate B2B data provider?
Accuracy depends on region and persona. Run a 200-record test against your own ICP across two or three vendors before buying. Waterfall tools like Clay and FullEnrich combine several sources to lift hit rates.
Is Apollo or ZoomInfo better?
Apollo is far cheaper and includes sequencing; ZoomInfo has deeper enterprise data, intent and ABM features on custom annual contracts.
What is waterfall enrichment?
Querying several data providers in order until one returns a verified email or phone, so you pay only for results and get higher coverage than any single source.
