🎮 Valve
Quick Summary
Valve Corporation is one of the most influential game companies in history — creator of the Half-Life, Counter-Strike, and Portal franchises, and operator of Steam, the world’s dominant PC game distribution platform.

Steam: The World’s PC Game Marketplace
Steam (launched 2003) is Valve’s most significant contribution to the game industry:
- Dominant PC digital distribution platform with 33,000+ games
- Early Access pioneer
- Steam Workshop for community mods
- Takes a 30% revenue cut from all game sales (criticized as a “Steam tax” by developers)
- Steam’s market share estimated at ~75% of all PC game digital sales
The Flat Organization
Valve operates with no managers, no hierarchy. Every employee is empowered to work on any project they choose. Projects form organically, and employees “vote with their desk” — physically moving to join projects they believe in.
This has created some of gaming’s most innovative products but also contributes to projects going dark (the notoriously absent Half-Life 3).
