About this dataset
ATS Company Directory: 9,935 Companies
A mapping of 9,935 companies to the applicant tracking system they use and the public job-board slug that serves their postings. Built by enumerating the public job board APIs of Greenhouse, Lever and Ashby. No private data, no scraping behind a login, and no personal data of any kind.
Verify any row yourself
Every row is independently verifiable, which is the point of publishing it. Take the vendor and the slug and call that vendor's public API:
greenhouse https://boards-api.greenhouse.io/v1/boards/<slug>/jobs
lever https://api.lever.co/v0/postings/<slug>?mode=json
ashby https://api.ashbyhq.com/posting-api/job-board/<slug>
No account or key needed for any of the three.
Columns
| Column | Meaning |
|---|---|
ats_vendor | greenhouse, lever or ashby |
company_name | The company name as the board reports it |
board_slug | The identifier used in that vendor's public API URL |
last_crawled | Date this board was last confirmed reachable (YYYY-MM-DD) |
Coverage
| Vendor | Companies | Crawled |
|---|---|---|
| greenhouse | 4,966 | 12 Jul to 1 Aug 2026 |
| ashby | 2,856 | 12 Jul to 17 Jul 2026 |
| lever | 2,113 | 11 Jul to 1 Aug 2026 |
| total | 9,935 |
Every (ats_vendor, board_slug) pair is unique. No row has an empty name or slug.
Limitations, stated plainly
- Boards disappear. A slug that resolved at crawl time can 404 later if the company stops using that vendor or closes its board. A spot check of 9 random slugs on 4 August 2026 found 8 still live and 1 Ashby board removed. Treat
last_crawledas the date the row was true, not a guarantee for today. - The Ashby rows are the stalest. Ashby was last crawled 17 July 2026, so those rows are roughly three weeks older than the Greenhouse and Lever rows.
- This is not every company on these platforms. Boards are discovered, not enumerated from a vendor-supplied list, because no such public list exists. Absence from this file is not evidence a company does not use the vendor.
- Company names come from the board itself and are not normalised. Casing and punctuation vary, and a few are lowercase slugs where the board never set a display name.
- Three other major systems are absent: Workday, SmartRecruiters and Taleo. They do not expose comparable open job board APIs.
Why this exists
No public dataset maps companies to their ATS vendor and board slug, yet it is the lookup you need before you can study hiring data across companies at all. It is the companion to our pay transparency dataset, which analyses 101,432 postings pulled from these same boards.
