Thompson Street Capital Partners (TSCP), a St. Louis-based private equity firm, today announced that its portfolio company, ATIS, has acquired AuditMate, a leading elevator asset management technology platform. The acquisition positions ATIS as the technology-enabled leader in elevator asset management by combining AuditMate’s best-in-class software platform with ATIS’ leading North American consulting, inspection, and managed services offering.

Building owners and property managers have historically lacked visibility into elevator maintenance performance. Together, ATIS and AuditMate create a modern platform that combines proprietary technology, portfolio intelligence, and expert execution to help customers improve elevator uptime, enhance compliance, reduce risk, and lower costs.

“The acquisition of AuditMate represents another important step in ATIS’ long-term strategy of building the leading technology-enabled platform across elevator managed services, consulting, and inspection,” said Tom St. Geme, Managing Director at Thompson Street Capital Partners. “By pairing AuditMate’s category-leading technology with ATIS’ North American network of more than 250 expert elevator consultants and inspectors in all major markets, we believe the combined company is uniquely positioned to deliver differentiated outcomes for building owners while continuing to lead the digital transformation of elevator management.”

ATIS plans to integrate AuditMate’s platform across its managed services offering, creating a unified operating platform that provides customers with continuous maintenance visibility, portfolio-wide analytics, and actionable intelligence supported by one of North America’s largest teams of elevator consultants and inspectors.

“Elevators are one of the most critical and historically opaque systems within the built environment,” said Jim Fox, CEO of ATIS. “Our vision is to fundamentally change that. By combining the industry’s leading technology and intelligence platform with our deep industry expertise, we are creating a smarter, more transparent operating model that drives better performance for our clients and elevates safety and reliability for the riding public.”

“At AuditMate, we set out to bring clarity to a complex and often misunderstood system,” said Ash Wilson, Founder and CEO of AuditMate. “Joining ATIS allows us to accelerate that mission, bringing together platform intelligence, analytics, and domain expertise to improve performance, accountability, and safety at scale.”

Terms of the transaction were not disclosed.
