Valve, a privately-owned gaming company, has managed to keep its financial information under wraps for years. However, leaked data from an ongoing court case has shed light on the company's employee count and payroll over its history. The document revealed that Valve has never had more than 400 employees, with 336 in 2021. Despite its small staff, Valve's gross pay has increased steadily, reaching $157 million in 2021. The company's gaming division saw significant growth between 2008 and 2014, coinciding with the release of popular titles like Left 4 Dead 2 and Dota 2. The hardware division also expanded in the mid-2010s with products like the Valve Index. The leaked data provides a rare glimpse into Valve's inner workings, showcasing its success in the competitive gaming market despite its relatively small workforce.
