About Kongregate

Kongregate is a game developer, publisher and web gaming platform operator whose work spans browser entertainment and free-to-play mobile games. Founded in 2006, the company built its early business around a community-driven portal for independently developed games, then expanded into mobile publishing, first-party development and ongoing support for established titles.

Its browser platform brought together community-submitted Flash, HTML5, Java and Unity games. Integrated achievements, badges and collectible Kongpanions connected individual games to a broader player community. Developer revenue-sharing and publishing partnerships also made the platform a route for independent creators to reach audiences and monetize their work.

Development and publishing

Kongregate’s portfolio includes collectible card games, idle and incremental games, role-playing games and browser experiences. Its development and publishing work includes Animation Throwdown: The Collectible Card Game, co-developed with Synapse Games; AdVenture Capitalist, developed by Hyper Hippo; and Burrito Bison: Launcha Libre, developed by Juicy Beast. Other projects include Bit Heroes Quest, Spellstone, SpongeBob’s Idle Adventures and TMNT: Mutant Madness.

The company combines game development with publishing, digital distribution, community management and live operations. Its platform infrastructure includes the Kreds virtual currency system and developer SDK and API integration, alongside marketing and analytics support. These activities connect its history as a browser destination with its mobile publishing business.

Evolution of the business

GameStop acquired Kongregate in 2010, followed by Modern Times Group in 2017. During this period, the company expanded its development capabilities through studio acquisitions and broadened its publishing portfolio.

In July 2020, Kongregate halted new portal game submissions and reduced forums and chat features as it shifted toward mobile live operations and first-party development. It subsequently explored blockchain-enabled games and the Bitverse franchise. In February 2024, Kongregate became an operating subsidiary of Monumental, with MTG receiving a minority stake in the combined entity. Kongregate continues to publish and support games through its operating facility and distributed teams.
