Api Group Corporation
A maker of fire-protection and safety services, it installs, inspects, and services fire alarms, sprinklers, elevators, and security systems for hospitals, factories, and data centers. It began in 1926 as an insulation arm of a St. Paul, Minnesota mechanical company, and "APi" comes from its original name, Asbestos Products Inc. It has grown by buying hundreds of smaller contractors since 2005.
