The Best B2B Data Providers of 2026
Company and contact data vendors compared on coverage, field accuracy, delivery and compliance posture.
B2B datasets are bought on two numbers: how many records match your ICP, and what share of those records are still true. Vendors advertise the first and rarely publish the second.
We sampled 500 random records per vendor and verified firmographics, contact validity and refresh dates by hand.

Frequently asked questions
Buy a dataset or scrape it?+
Buy when the data is commodity firmographics and freshness beyond a month is acceptable. Scrape when the field you need is niche, or when you need it daily.
How do I evaluate a data vendor?+
Demand a 500-record random sample — not a curated one — and verify it by hand. Measure fill rate per field, not just record count.
