Independent benchmarks for B2B data providers.

Eight independent benchmarks cover email, phone, people, company, live profile, intent, jobs and technographic data, so you can pick a provider for the data you actually need. Every provider is run on the same frozen test set, mostly through the same gateway, and results are graded against objective truth or by a blind judge. Third-party reviews aggregated with sources. No paid placement.

FAQ

What is B2BDataBenchmarks?

Independent, reproducible benchmarks of B2B data providers, split by data type: email, phone, people, company, live profiles, intent, jobs and technographics. Every provider is run on the same frozen test set, results are graded against objective truth or by a blind judge, and the aggregates behind every score are published. No paid placement.

How are providers scored?

Every provider is run on the same frozen test set through its native API; the few whose per-call price is high run on its first 10 to 50 entries. Results are graded against objective ground truth (email verifiers, carrier lookup, registries and filings) or blind (the judge never sees which provider returned a record). Raw responses hold personal data and stay private; the per-provider aggregates behind every number are published.

What do the A to D badges mean?

They place a value in its field: A is the top fifth of the providers measured on that metric in that run, B the rest of the upper half, C the lower half, D the bottom fifth. Direction comes from the metric, so a fast latency earns an A the same way a high match rate does. Review ratings use fixed bands instead, since they come from third-party platforms rather than from our runs.

How are leaderboards ranked?

By overall grade: the weighted mean of a provider's grades on every metric of the suite, core and specific, A = 4 to D = 1, with the headline metric (match rate or coverage) weighing most. A provider that matches everything but returns poor data does not top the table. Ties are broken on the headline metric, and every column can be re-sorted.

Is placement paid?

No. There is no paid placement, no affiliate links, and the dataset is released under CC BY 4.0. Providers win some suites and lose others, and that is the point.

Suggest a data provider

Not automatic, on purpose: a human has to get access (or request it when there's no self-serve), plug in an API key, adapt the frozen test files to the provider's schema, then run the suites. Leave the details below and we'll take it from there, usually within a few weeks.
