Sales Prospect & Contact Data
Best AI tools for B2B prospect and contact data with accuracy and GDPR compliance.
The verdict
For Sales Prospect & Contact Data, Amplemarket ranks #1 — A-tier at 8.3/10. 5 tools ranked on five transparent scoring axes.
Multichannel B2B outbound with AI agents and 5-tool deliverability stack
Why A-tier?
The strongest prospect-data fit here, pairing a large verified database with the lowest tested bounce rates and a full deliverability stack. Enterprise-zone pricing is the main barrier.
All-in-one B2B sales platform with 275M+ contacts and free tier
Why B-tier?
A huge database with the most powerful filters and the most generous free tier, ideal for startups. Verified counts shrink sharply and documented bounce rates are high.
B2B contact data with Chrome extension for LinkedIn lookups
Why B-tier?
A best-in-class browser extension with full compliance on every tier, strong for quick lookups. Declining phone accuracy and a very low Trustpilot rating temper it as a standalone platform.
Real-time B2B contact search engine with 1.7B+ claimed contacts
Why B-tier?
The largest claimed database with a real-time search model and strong support, suited to US high-volume lookups. Data quality and contract terms are recurring concerns.
Pay-as-you-go B2B contact data without subscription commitment
Why C-tier?
A pay-as-you-go data tool with no subscription lock-in and real-time verification, useful for one-off campaigns. Thin review presence and small share make it hard to verify at scale.
