Company Headcount API FAQs

What is historical headcount data?

Historical headcount data is a time series of employee counts for a company, captured as monthly snapshots. It shows how a company's workforce has grown or contracted over time, including department-level breakdowns for each period.

How can I track company headcount changes?

Use the Company Headcount API to query any company by domain. The API returns the current observed employee count along with monthly snapshots for the latest 12 months. Pass the returned nextCursor to fetch each earlier year, so you can compare headcount across any time period and track changes programmatically.

Why can the headcount differ from a company's official number?

The API returns an observed employee count, based on the professional profiles linked to a company. It can differ from the number a company reports, for example when employees have no public profile. Use the trend over time to compare companies and spot growth.

Can I get employee count by department?

Yes. Every response includes a departmentHeadcount breakdown with counts for engineeringTechnical, sales, marketing, productManagement, finance, humanResources, design, cSuite, legal, and more. Each historical snapshot also includes department data so you can track department-level trends over time.
