Private equity firm Littlejohn is exiting The Hiller Companies after a three-year sprint that transformed the fire and life safety specialist through aggressive expansion. Wind Point Partners is buying the business, according to PEHub, though neither side is talking numbers.

The Greenwich, Connecticut-based firm announced the sale more than three years after picking up Hiller in September 2022. Since then, both parties say they executed a "transformational" growth strategy that reshaped the company's profile and market position.

Twenty Acquisitions in Three Years

The transformation wasn't subtle. Hiller expanded across new markets, brought in fresh leadership talent, shifted toward higher-margin recurring service contracts, and closed over 20 acquisitions during Littlejohn's ownership. That's roughly one deal every two months, a pace that fundamentally changed what Hiller looks like today.

CEO Santiago Perez praised Littlejohn as an "outstanding partner," noting the firm poured resources into people and infrastructure while letting Hiller preserve its culture and customer-focused operating style. He said the company now has a strong foundation heading into its next chapter under new ownership.

Brian Michaud, a managing director at Littlejohn, framed the Hiller deal as typical of the firm's playbook: identify solid companies in core sectors, then partner with management to accelerate value creation. Translation: buy well-run businesses, help them grow faster, and sell at a profit.

The transaction still needs regulatory sign-off and to clear standard closing conditions. Baird and Harris Williams advised Littlejohn on the sale, with Gibson, Dunn & Crutcher handling legal work.

Littlejohn manages approximately $8.7 billion in assets, focusing on private equity and debt investments in middle-market industrial and services companies.
