So low, in fact, that even ADP (the worst ATS in the history of the world – it makes Brassring look like the Holodome) has about 5x more share of the ATS market than Greenhouse, and even ADP doesn't really ever think or care about the fact that somewhere in their portfolio, they happen to have some ATS they picked up in some random acquisition; similarly, the market share for Lever is less than that of Ceridian, who doesn't really even have an ATS product to begin with (although it's been rumored to be released for like 5 years now, Dayforce still isn't a recruiting software). So this generation, but Lever in particular, have a long way to go.
