The size signal
Workday carries 12.7% of the open roles from 4.3% of the companies. Its median customer here has 37 roles open against 5 for Ashby. In this sample it is not a startup system: it is what a company moves to once it is hiring at a different scale.
Cross-check
The ranking above counts companies that are hiring today, so a system used by companies in a quiet phase would be understated. A second, independent measurement avoids that: which system each company runs, across all 10,300 companies where we could identify one, whether or not it has a role open. It puts Ashby first again, at 26.9% against 23.7%.
Method, and what this does not measure
Every number here is counted from job posts read directly from each company's own careers page, every morning. Nothing is modelled, estimated or weighted. The companies come from the published portfolios of venture funds — 36,699 companies examined in total.
This is not ATS market share. Three restrictions apply, and they all push the same way:
- Only venture-backed companies. Nothing here says anything about the wider market.
- Only companies with at least one role open, in the headline figure. The cross-check above removes this restriction and gives the same answer.
- Only systems that expose a public job feed. Of the 10,300 companies where we identified a system, 8,559 run one we can read. The remaining 1,741 — LinkedIn Jobs (583), Notion (497), Welcome to the Jungle (206), Gem (113), Indeed (86) — are counted nowhere.
26,399 of the 36,699 companies examined had no system we could identify at all: a custom careers page, no careers page, or no longer trading. They are excluded, not assumed.
Use these numbers. They are free to quote, with or without attribution. If you want the underlying counts broken down differently — by country, by sector, by company size — ask and I will run it.
