MaintainX raises $150M at $2.5B valuation to bring AI-powered equipment maintenance to the industrial frontline

MaintainX, an equipment maintenance startup helping industrial teams keep their equipment running with fewer breakdowns and more brains, just raised $150 million in fresh funding. The new round brings the company’s valuation to $2.5 billion and signals strong investor confidence in a space that’s often overlooked but mission-critical—equipment maintenance.

The Series D was led by Bessemer Venture Partners and included Bain Capital Ventures, D.E. Shaw Ventures, Amity Ventures, August Capital, Founders Circle Capital, Sozo Ventures, and Fifth Down Capital. A few heavy-hitting angels joined the round too: Rahul Mehta, co-founder of DST Global, and Hashicorp CEO Dave McJannet.

AI Maintenance Startup MaintainX Hits $2.5B Valuation with $150M Series D Funding

MaintainX says it will use the funding to deepen its AI and machine health monitoring tools, push further into predictive maintenance, and grow its enterprise asset management features. The goal: help companies move from waiting for machines to break to spotting problems before they happen. The company also plans to invest in partnerships and talent to meet growing demand, especially as skilled labor becomes harder to find.

“Equipment failures cost companies $1.4 trillion annually, and many still rely on outdated tools. We built MaintainX to change that,” said Chris Turlica, CEO and co-founder. “In today’s unpredictable global environment where supply chain disruptions and external cost pressures are hard to control, our mission is more important than ever. I’m proud to see our customers offset external pressures by reducing unplanned asset downtime, parts, and labor costs while turning their frontline professionals into the knowledge workers they deserve to be with AI.”

MaintainX isn’t trying to replace humans with machines—it’s trying to make human workers a lot more effective. Its software puts AI-generated insights in the hands of technicians on the factory floor and executives in the office, helping both make better calls about maintenance, uptime, and safety.

The startup’s timing looks spot-on. Industrial companies are under pressure to squeeze more performance out of aging equipment without adding more headcount. MaintainX steps in with a platform that collects operational data from machines—regardless of what sensors or systems are in place—and turns it into insight. That means less guesswork, fewer breakdowns, and less wasted time.

Byron Deeter, partner at Bessemer, said what convinced them was the customer feedback. “MaintainX has achieved remarkable product-market fit by addressing a critical challenge that affects virtually every physical asset-driven industry,” he said. “Their AI-powered insights are what truly differentiates MaintainX in the market—this intelligent layer transforms raw operational data into predictive recommendations that drive unprecedented value creation.”

Merritt Hummer, a partner at BCV, added that the shift isn’t just about tech—it’s about business survival. “Companies are increasingly turning to operational technology not just to improve performance, but to protect margins and preserve jobs,” she said. “MaintainX is driving this shift… It introduces a new operating model where AI surfaces insights, predicts failures, and unlocks entirely new revenue streams and efficiencies.”

Customers seem to agree. Jeremiah Dotson, Facility Maintenance Manager at Amfab Steel, said, “With MaintainX AI, it is even easier to digitize our preventive maintenance workflows, and our technicians can now use CoPilot to get accurate, real-time answers the moment they need them instead of having to dig through lengthy manuals and data—it’s like having an expert on hand 24/7.”

Founded in 2018, San Francisco-based MaintainX has quietly become a key player in industrial operations, now used by over 11,000 companies managing more than 11 million assets. The platform processes 27 million work orders and over 370,000 safety procedures each year. Customers report slashing unplanned downtime by over 30% and saving up to a third in monthly maintenance costs.

Unlike the current solutions, MaintainX is focused on something much harder to build: a product that industrial teams actually rely on. With $254 million in total funding, it’s looking to push even deeper into manufacturing, facilities management, distribution, and other asset-intensive sectors—all while ensuring the machines stay operational and the people in charge have the information they need, when they need it.
