ST. LOUIS, MO (September 24, 2024) – ATIS, a premier provider of elevator and escalator safety inspections, consulting and managed services, today announced it has received a growth investment from Thompson Street Capital Partners (TSCP), a leading private equity firm headquartered in St. Louis.

“For more than six decades on a combined basis, our team has been pioneering the most innovative and holistic suite of services and building an incredibly strong reputation as a trusted advisor to our clients,” said Chip Smith, ATIS co-founder and CEO. “We’re excited to now partner with TSCP to extend our leadership position and, with significantly greater resource backing, accelerate the expansion of our team’s unparalleled end-to-end vertical transportation services, world class customer care, and geographic reach.”
