Valve, the makers of Steam, Half-Life and CounterStrike, made ~$17B in revenue this year with ~336 employees.That's >$50M per employee, the highest for any (non-crypto) company in the world. The average pay is ~$1.3M/person. One of the most efficient businesses of all time.
Damn this is impressive! Though it doesn't surprise me with the constant rise of PC gamers. I talked to one of my coworkers yesterday about video games and him and his girlfriend are pretty much done with console gaming and will only be upgrading his desktop and stick to PC gaming for now on.
