About PeopleDataLabs
The B2B data graph under other people's enrichment.
PeopleDataLabs was founded in 2015 in San Francisco by Sean Thorne, Justin Hartzman and Hossein Azizi. The company raised a $45M Series B led by Craft Ventures in 2022 and built one of the larger open person-data graphs on the market, paired with a company graph and a job-posting feed. The product is shipped as APIs (person enrichment, person identify, person search, company enrichment, company search, autocomplete, IP enrichment, job-posting search, cleaner endpoints) and as a bulk dataset that lands in S3, Snowflake, Databricks, Azure or GCP with delta files for incremental refresh.
What sets PeopleDataLabs apart from the sales-stack neighbours is the audience. ZoomInfo, Apollo and Cognism sell a UI to SDRs. PeopleDataLabs sells a dataset to data engineers, ML platforms and product teams who build the enrichment that other people see. A lot of the contact databases, recruiting tools and ICP scorers your sales team logs into are running on a PDL feed underneath, sometimes with the brand stripped, sometimes co-licensed.
The reason to pull PeopleDataLabs into a warehouse is that the value of a data graph is the lift it produces on your own customer base, not the row count on the vendor's homepage. Coverage rate against your customer list, attribute decay between refreshes, ML-feature uplift on a churn or lead-score model and the build-versus-buy line on a homegrown enrichment service all live in the join between the PDL feed, the CRM, the product database and billing. Inside an API console those numbers stay invisible; in a warehouse they become the number you renew on.
