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.
Benchmarks, by data type
Providers are rarely good at everything. Each benchmark isolates one kind of data, with the metrics that matter for it, so you can choose on the dimension you actually buy.
Work-email finding and verification: how many addresses come back, how many verify as valid, and what each valid one costs.
Mobile and direct-dial numbers: match rate, validity, line type and what each valid mobile costs.
Who a person is, what they do and where: identity, employer, title, seniority, history and price per profile.
Firmographics for a known domain: match, name, industry, headcount, HQ, founding year and price per company.
Live profile fetch from a public professional profile URL: does the answer show the job a person holds today, how fast, and at what price.
Buying signals: how many accounts are identifiable, how accurate and predictive the signals are, and what each one costs.
Open job postings for a known company: how many employers and roles the provider finds, how many it returns that are closed, and cost per job.
Which technologies a company runs: coverage, how many returned technologies are really on the site, how much of the visible stack is found, and cost per lookup.

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.
