What is PeopleDataBenchmarks?
An open, reproducible benchmark of people-data APIs — people search, profile enrichment, email finding and phone enrichment. Every provider answers the same frozen test set, every raw response is published, and results are graded blind or against objective truth (email verification). Aggregated third-party reviews for every provider, with sources. No paid placement.
How are providers scored?
Every provider answers the same frozen test set through its native API. Results are graded blind (the judge never sees which provider returned a record) or against objective ground truth, and every raw request, response and judge call is published so the numbers can be independently re-graded.
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 — that is the point.
