Professional profiles with career history, education, and real-time signals. Specter’s people dataset covers 550M+ profiles — founders, executives, investors, and operators. Each person has a stable person_id used across every people endpoint.

​
Data categories

  • Profile — name, tagline, about, location, profile picture, LinkedIn follower and connection counts.
  • Career history — experience[]: companies, titles, tenure, and progression (is_current, job_order).
  • Education — education[]: institutions, degrees, and fields of study.
  • Skills & attributes — skills, languages, seniority, years of experience, education level.
  • Signals — talent_signal_ids, and investor_signal_ids (usable in investor endpoints when available).
  • Social links — LinkedIn, Twitter and GitHub URLs, plus linkedin_num_id and linkedin_urn.

Highlights

The highlights array flags high-signal attributes for evaluating a person — especially founders. Documented values include:
  • prior_exit — founded or was part of a company with a successful exit.
  • serial_founder — founded more than one company.
  • prior_vc_backed_founder — previously founded a venture-backed company.
  • prior_vc_backed_experience — worked at a venture-backed company.
This list is being expanded, so treat it as non-exhaustive. Pair highlights with company filters to spot strong founding teams.

Notes

  • Most fields are nullable — only core identity (person_id, name, LinkedIn URL) is guaranteed.
  • Reverse email lookup returns a score from 1–10; 7 or higher is a reliable match; no match returns 204.
  • Bulk lookups omit unknown identifiers; bulk enrich returns a found/queued status per row, and only found rows are charged.
  • Enriching an unknown person queues them for sourcing — retry the lookup shortly after.
