The Claim
There is no single ATS "everyone" uses — the market is split by company size and hiring volume — but Greenhouse, Workday Recruiting, iCIMS, Lever, and Ashby account for most mid-market and enterprise hiring, with the mix shifting further after 2025's wave of acquisitions.
The Evidence
Greenhouse's own newsroom confirms its #1 ranking across four G2 Winter 2026 categories with a 98% satisfaction rate. Independent comparison sites (Pin.com, Gem) corroborate this and add market-consolidation context: SAP acquired SmartRecruiters, Workday absorbed Paradox, and iCIMS acquired Apli, all in 2025 — reshaping which vendors serve which segment. Jobscan's analysis of Fortune 500 careers pages found 97.8% use an ATS.

Step-by-Step: How to Find Out Which ATS a Specific Employer Uses
- Check the application URL when you click "Apply" — greenhouse.io, myworkdayjobs.com, icims.com, jobs.lever.co, and jobs.ashbyhq.com are common giveaways.
- Look at the careers page footer — many companies list "Powered by [ATS name]" in small print.
- View page source on the careers page and search for the ATS name in the HTML if the URL doesn't reveal it.
- Ask your recruiter directly — this is a normal question and doesn't hurt your candidacy.
- Tailor your resume format accordingly — Workday and iCIMS in particular are known for stricter parsing of complex formatting, so simpler layouts parse more reliably.
