APi Group is a business services company focused on fire and life safety, electronic security, and elevator and escalator services, plus a specialty contracting business. APi operates through two segments: Safety Services (~67% of revenue), which covers fire protection, electronic security, and elevator/escalator services across North America, Europe, and Asia-Pacific; and Specialty Services (~33% of revenue), a more project-driven, lower-margin segment covering specialty contracting, fabrication, and infrastructure work for end markets like data centers, advanced manufacturing, and utilities. APi's go-to-market strategy is "inspection-first" — the company leads by selling legally mandated fire and life safety inspections, then converts those relationships into follow-on service, repair, and project work. Management estimates every $1 of inspection revenue generates $3–$4 of downstream service work. About 54% of revenues come from inspection, service, and monitoring, with a long-term target of 60%+. The business model is asset-light, with capex typically below 1.5% of revenues, and roughly 70–75% variable costs, primarily labor. M&A is a core part of APi's growth model — the company has completed 140 acquisitions since 2005, deploying roughly $250M per year in bolt-ons, and is actively building an elevator and escalator platform with a stated goal of reaching $1B+ in that vertical.
