Hey Sean, Just wanted to post a response I received from Clay support on this topic:
Our Find People search isnât a 1-to-1 mirror of LinkedIn. We donât connect to your LinkedIn cookie session or scrape the site directly; instead, we ingest profiles from several third-party data providers. That means (1) private or semi-private profiles that only appear when youâre logged into LinkedIn wonât come through, and (2) we run our own quality filters (e.g., drop profiles with fewer than 10 connections).
