Valve had its employee and payroll data leaked through a poorly redacted document in an antitrust lawsuit in May, offering a rare glimpse into the company's small but impactful workforce over the years.
As first noticed by SteamDB's Pavel Djundik, Valve's significant influence in PC gaming transactions has been maintained by just a few hundred employees. In 2021, Microsoft estimated Valve's annual revenue at $6.5 billion, roughly on the same scale as EA's $7.5 billion in 2024 revenue. But Steam achieved those numbers with around 350 employees, compared to well over 13,000 people employed by EA. The disparity highlights just how much money Valve brings in with a relatively small workforce. And a lot of that is thanks to the chunk of revenue Valve takes from every sale on Steam. The dominant PC gaming marketplace has seen a massive increase in the number of annual game releases since 2012 or so, thanks to initiatives like Steam Greenlight and Steam Direct.
The size of the "Steam" department inside Valve has shrunk in recent years, from a peak of 142 employees in 2015 down to just 79 in 2021. From the outside, having just 79 employees keeping track of more than 11,000 Steam releases in 2021 is a pretty incredible ratio.
Valve's "Games" department has represented a majority of the company's headcount since 2003. That has remained true (though to a lesser extent) even in more recent years, as Valve's output of new games has become much more occasional. It seems likely a large number of those Games department employees are devoted to ultra-popular Valve games like Dota 2 and Counter-Strike 2, which enjoy tens of millions of players and need significant support work.
The leaked data also shows the slow rise of Valve's small Hardware department, which started with just three employees in 2011 as the company began work on its doomed Steam Machines initiative. Transitioning into the Valve Index era in the late 2010s, the hardware department still represented just a few dozen people and a paltry 3 to 4 per cent of the company's annual payroll.
By2021 and the run-up to the Steam Deck, the Hardware division still makes up just 12 per cent of Valve's small total headcount. It's impressive that such a small team was able to create a portable gaming device that quickly spawned a whole micro-industry of imitators. We can only hope the Hardware team got a little more employee support in the wake of the Steam Deck's market success.
