Companies that use CATS ATS

Source: Analysis of Linkedin bios of 354 companies that use CATS ATS

I noticed that CATS ATS users span an incredibly diverse range of operational focuses, but they share a common thread: they're hands-on operators doing specialized work. These aren't tech startups building SaaS products. Instead, I see staffing and recruiting firms placing technical talent, government contractors supporting defense and intelligence missions, construction and manufacturing companies building physical products, healthcare providers delivering patient care, and facility services companies maintaining critical infrastructure. Many are B2B service providers who staff projects, manage contracts, or provide specialized expertise to other organizations.

These are predominantly small to mid-sized established businesses, not startups. The employee counts cluster heavily in the 11-50 and 51-200 ranges, with very few showing funding rounds or venture backing. Many explicitly mention decades in business. They're past survival mode but not massive enterprises. They're at the stage where they have steady operations, need to professionalize HR processes, but don't have budgets for enterprise-grade ATS systems.
