Valve is a powerful player in the video game industry. Take a look at how How-To-Geek.com views their operations.
Valve, the game developer behind franchises like Half-Life and Portal, as well as the company that owns the virtual PC game store Steam, has around 360 employees (as of 2016). In 2017—a year in which Valve released no games—the Steam store made $4.3 billion in revenue. Back in 2011, Valve founder and President Gabe Newell said that, on a per-employee basis, the company is the most profitable company in the United States.
