Valve Corporation

Valve Corporation develops video games, operates the Steam digital distribution platform, and manufactures hardware from its headquarters in Bellevue, Washington. Founded on August 24, 1996, by former Microsoft employees Gabe Newell and Mike Harrington, the company released its first title Half-Life in 1998. Steam, launched in 2003, serves as the primary revenue driver through a 30% commission on game sales and in-game transactions.

Valve generated $5 billion in revenue during 2023, with Steam accounting for the majority. Major titles include the Counter-Strike series, Dota 2, Team Fortress 2, and Portal. Loot boxes and cosmetic items, particularly in Counter-Strike: Global Offensive (CS:GO) and Counter-Strike 2 (CS2), form a significant revenue stream, with CS2 skin and case sales exceeding $1 billion in 2025. The company maintains a flat organizational structure with approximately 336 employees as of 2021 and similar headcount estimates through 2025. Data current as of February 2026.

Founding and Early Development

Valve began operations as Valve, L.L.C. in Kirkland, Washington, on August 24, 1996. Gabe Newell and Mike Harrington, both ex-Microsoft employees, established the company. Harrington sold his stake to Newell in 2000, leaving Newell with majority ownership exceeding 50%. The entity reincorporated as Valve Corporation in 2003 and relocated to Bellevue.

Initial development focused on modifying the Quake engine into GoldSrc for Half-Life, released November 19, 1998. Half-Life sold millions of copies and shaped first-person shooter mechanics, winning over 50 game of the year awards. Half-Life 2 launched October 16, 2004, selling 12 million copies by 2011 and introducing the Source engine with advanced physics via the Havok system.

Major Game Franchises

Valve produces multiplayer titles with ongoing updates and community mod support. All major ongoing titles use free-to-play models supported by cosmetic microtransactions.

Half-Life Series

The franchise that launched Valve. Half-Life (1998) used the GoldSrc engine and featured continuous gameplay without level-loading screens, a major innovation for the time. Half-Life 2 (2004) introduced the Source engine, facial animation, and physics-based puzzles. Episodes One (2006) and Two (2007) continued the story. Half-Life: Alyx (2020) marked Valve's return to the series as a full VR title, receiving near-universal critical acclaim.

Counter-Strike Series

Counter-Strike originated as a Half-Life mod by Minh Le and Jess Cliffe in 1999. Valve acquired the mod and released a standalone version in 2000. Counter-Strike: Source (2004) ported the game to the Source engine. Counter-Strike: Global Offensive (CS:GO) launched August 21, 2012, and introduced weapon cases with cosmetic skins, creating a multi-billion dollar secondary market. Counter-Strike 2 launched September 27, 2023, replacing CS:GO on a new Source 2 engine.

• Counter-Strike (1999/2000): Originated as Half-Life mod, standalone in 2000
• Counter-Strike: Source (2004): Source engine port
• Counter-Strike: Global Offensive (2012): Introduced loot box economy
• Counter-Strike 2 (2023): Source 2 engine; replaced CS:GO

Team Fortress 2

Released October 9, 2007 as part of The Orange Box, Team Fortress 2 introduced Valve's cosmetic item economy in June 2010 before going free-to-play on June 23, 2011. The game pioneered the hat and cosmetic model that Valve later deployed across other titles. As of 2025 TF2 remains active despite being over 17 years old, sustained entirely by cosmetic purchases and community activity.

Portal Series

Portal (2007) shipped inside The Orange Box. Its puzzle mechanics using a portal gun received widespread praise. Portal 2 (2011) expanded the single-player campaign and added cooperative play, earning near-perfect review scores. No Portal 3 has been announced.

Dota 2

Dota 2 launched July 9, 2013, as a free-to-play multiplayer online battle arena. The International, Valve's annual Dota 2 championship, generated prize pools funded by battle pass sales, reaching $40 million in 2021 -- the largest prize pool in esports history at the time. Cosmetic bundles and battle passes provide recurring revenue without affecting gameplay.

Steam Platform

Steam launched September 12, 2003, initially for Half-Life 2 updates and distribution, then expanded to third-party titles. It reached 67 million monthly active users by 2017. Gross revenue on Steam totaled $17 billion in 2025. The platform applies a 30% revenue share on most sales, reduced to 25% for developers earning over $10 million and 20% for earnings over $50 million.

Steam holds the largest share of the PC digital distribution market. Features include the Steam Workshop for user-generated content, Steam Community Market for item trading, Steam Remote Play, and Steam Deck hardware integration. The Steam Community Market applies a 15% transaction fee on all player-to-player trades, with 5% going to the game publisher and 10% to Valve.

Loot Boxes and Microtransaction Revenue

Valve implements loot box systems through weapon cases in Counter-Strike titles. Players purchase keys to open cases containing cosmetic weapon skins at randomized rarity tiers. CS:GO and CS2 cases generated over $1 billion in revenue for Valve in 2025, with case key sales alone contributing approximately $800 million. The skin economy operates via the Steam Community Market, where players trade items and Valve collects a 15% transaction fee.

The CS2 skin secondary market is extensive. Individual rare skins have sold for six figures, and one CS2 skin reportedly traded for over $1 million. The total value of the skin economy is estimated in the billions. Team Fortress 2 introduced the cosmetic item economy in 2010, and Dota 2 uses battle passes and cosmetic bundles, generating billions in cumulative revenue since launch.

Organizational Structure and Headcount

Valve employs a flat structure without traditional managers, allowing employees to select projects. The approach is outlined in the company's public Employee Handbook. Headcount stood at 336 in 2021, with estimates between 330 and 360 through 2025. The company remains privately held, with Gabe Newell as majority owner. No public financial filings are required.

The flat structure means product decisions, release timing, and resource allocation are driven by employee interest rather than a top-down management chain. Critics note this can lead to long development gaps; no mainline Half-Life game shipped between Half-Life 2: Episode Two (2007) and Half-Life: Alyx (2020).

Hardware

Valve has entered hardware manufacturing on multiple occasions. The Steam Controller (2015) attempted to bring analog input to PC gaming. Steam Machines (2015) were Linux-based PCs designed to bring Steam to the living room; both lines were discontinued. The Steam Deck, announced in July 2021 and released February 25, 2022, is a handheld gaming PC running SteamOS. Multiple Steam Deck revisions have followed, and the device represents Valve's most commercially successful hardware venture.
