The Hiller Companies

What The Hiller Companies does

The Hiller Companies is a U.S.-headquartered, private fire protection and life safety services company founded in 1919 and based in Mobile, Alabama. It provides end-to-end fire protection services — design, engineering, installation, commissioning, inspection, maintenance, repair, and 24/7 emergency response — for commercial, industrial, marine, healthcare, data center, power generation, military, and government customers. Its product portfolio spans fire extinguishers, alarm systems, mass notification, detection (flame, smoke, gas, air sampling, linear heat), suppression (CO2, foam, dry chemical, wet chemical, water mist, aerosol, halon alternatives), fire sprinklers, and clean agent systems, supported by proprietary technology including Hiller Water Mist (the first FM-approved water mist system, 1995), CFD fire modeling for BESS and explosion prevention, and the only UL-listed clean agent fill station in Phoenix, Arizona.

The company generates revenue through a mix of recurring services (inspection and maintenance contracts, UL central-station alarm monitoring) and project-based work (design and installation, special hazard protection, hardware sales), with pricing provided via custom quotes rather than published rate cards. Sales are delivered through a direct enterprise field-sales model leveraging field-deployed NICET-certified technicians across 18+ U.S. office locations. The customer service layer is anchored by a ServiceTrade-powered Partner Portal that handles scheduling, electronic inspection reports, eQuotes, and service history. Marquee customers include the U.S. Navy (fire protection on every combatant ship), the New York Subway, the Smithsonian, Harvard Library, TVA, and Mitsubishi.

Following Pon Holdings' 2012 acquisition, Littlejohn & Co. made a strategic growth investment in September 2022, with Pon remaining a significant investor. Under new professional management (CEO Santiago Perez, March 2023; CFO Tony Ciccone, October 2022; CRO Duane Jenkins, July 2023), Hiller has pursued an aggressive buy-and-build strategy, executing roughly 40 acquisitions since 1970 and accelerating to 5 deals in 2023, 5 in 2024, ~12 in 2025, and 6 in 2026, dramatically expanding its U.S. geographic footprint, vertical coverage, and capability set.
