In Monsters, Inc., what is the name of the company where Sulley and Mike work?

In Monsters, Inc., Sulley and Mike work for Monsters, Incorporated.

The company is the story’s central workplace and the main source of energy for Monstropolis. Its employees enter children’s bedrooms through numbered doors and collect screams, which are processed and stored in canisters for the city’s use.

The title is an abbreviation of the company name, so viewers may remember “Monsters, Inc.” more readily than “Monsters, Incorporated.” The distinction matters because the film uses the full corporate name in signs, workplace references, and the company’s official identity.

The company’s system changes after Sulley and Mike discover that children are not toxic to monsters. When laughter proves more powerful than screams, the factory is reorganized around making children laugh. The ending therefore changes both the company’s energy source and its relationship with the human world.
