Best Free B2B Contact & Company Data Tools (2026)
Free doesn't have to mean useless. These b2b contact & company data tools offer useful free tiers that go beyond a 14-day trial. Some are free forever with real limits; others are freemium with enough value to run on indefinitely.
Our Pick for Free: Apollo.io
Apollo's free tier gives you 10,000 email credits per month plus basic sequencing and a dialer. No credit card, no time limit. Most free data tools cap you at 50-100 lookups. Apollo gives you 10K.

What's the best free B2B data tool?
Apollo.io. 10,000 email credits per month, basic sequencing, and a dialer. No credit card required, no time limit. It's the most generous free tier in B2B data.
Are free B2B data tools accurate?
Free tiers generally have the same data quality as paid plans. Apollo's free data accuracy is identical to its paid tiers. The limits are on volume, not quality.
Can you run cold outbound on just free tools?
Yes. Apollo (free data + sequences) and HubSpot (free CRM) give you a complete outbound stack at zero cost. Add Fireflies for free call recording. The limits are real but workable for 1-2 reps.
