LastRound AI - ATS Company Directory
Snapshot: crawled 11 July to 1 August 2026

WHAT THIS IS
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, no personal data of any kind.

Every row is independently verifiable. Take the vendor and the slug and call
that vendor's public API yourself:
  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>

FILE
lastroundai-ats-company-directory-2026-08.csv

COLUMNS
  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
  greenhouse   4,966 companies   crawled 12 Jul to 1 Aug 2026
  ashby        2,856 companies   crawled 12 Jul to 17 Jul 2026
  lever        2,113 companies   crawled 11 Jul to 1 Aug 2026
  total        9,935 companies

Every (ats_vendor, board_slug) pair is unique. No row has an empty name or slug.

LIMITATIONS, STATED PLAINLY

1. 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_crawled as the date the row was true, not a guarantee for today.

2. 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.

3. 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.

4. 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.

5. 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. It is the
lookup you need before you can study hiring data across companies at all, and
it is the companion to our pay transparency dataset, which analyses 101,432
postings pulled from these same boards.
