The portfolio focuses on mid-core games spanning a wide range of genres. Kongregate is the home for several idle/clicker games, including Adventure Capitalist, Crusaders of the Lost Idols, and Anti-Idle: The Game.

On the web portal, users can upload Adobe Flash, HTML 5/JavaScript, Shockwave, Java or Unity games with integrated high scores and achievement badges.[3][1][4]


Kongregate was released on October 10, 2006 by siblings Emily and Jim Greer into an alpha testing phase, which lasted until December 2006.[5] During this time, game developers and players tested the site's interface and functionality. The site formally entered the beta testing phase on March 22, 2007.[6][7]In December of the same year, the site was formally opened to the public.[3] As of July 2008, Kongregate had raised around $9 million in capital from investments by Reid Hoffman, Jeff Clavier, Jeff Bezos, and Greylock Partners.[8]

On July 23, 2010, GameStop announced an agreement to acquire Kongregate.[2][9] Because of Gamestop's purchase of Kongregate, developers who work through Kongregate can have their content promoted to people who shop at a GameStop store. Kongregate also provides a way for creators of games on Facebook to expand their potential audience.[10]

In early 2013, Kongregate announced a $10 million fund devoted to mobile gaming.[9] The new mobile division is led by former Zynga executive Pany Haritatos.[11] In 2014, the site introduced Kongpanions, acting as a trophy system and metagame in the form of small creatures, whether animals or personified objects. The Kongpanions that players collect can then be used in some games on the site.[12]

Kongregate announced plans in October 2016 to help developers bring their games to the Steam distribution platform with an updated software development kit to make it easy to port games between their web, mobile, and the Steam platforms (Windows, macOS, and Linux), and to support data sharing between these for players. This enabled games to take advantage of microtransactions through the Steam store for titles otherwise normally free-to-play.[13]

In 2016, Kongregate received Apple Editors' Choice for BattleHand and The Trail,[14] and received Google Play Editors' Choice for Animation Throwdown and AdVenture Capitalist.[citation needed] BattleHand and The Trail also were voted as Best of 2016 by Apple, and Animation Throwdown and The Trail were voted Best of 2016 by Google Play.[citation needed]

On June 20, 2017, Kongregate announced it had closed a deal to be acquired by Swedish entertainment company Modern Times Group[15] for $55 million. This follows MTG's recent purchase of 51% of Hamburg-based online game developer InnoGames in 2016 and 2017. Planned as part of the deal is a change in focus from hosting third-party games to driving game development as well. "[...]we’ll be deepening our investment in several areas, from marketing/marketing tech to platform engineering. We’re also going to be investing in first-party development and potential acquisitions of our own within the games space," said CEO Emily Greer.[16]

On October 5, 2017, Kongregate acquired Chicago-based Synapse Games, the developer of Animation Throwdown.[17]

On May 2, 2019, Kongregate announced that co-founder and CEO Emily Greer was leaving the company. She was replaced by COO Pany Haritatos as interim CEO.[18]


In November 2018 Kongregate opened Kartridge, a digital storefront focusing on independent games.[19] The storefront is available via browser or desktop app and features both premium paid games and free browser based titles.[20] Unlike other storefronts such as Steam, Kartridge is a heavily curated store. Kongregate hopes this curation will help spotlight quality games and address discoverability issues indie games commonly face.[21]
