Devsisters, a publicly owned company headquartered in South Korea, was founded in 2007 and operates with approximately 300 employees. The company specializes in manufacturing and developing mobile entertainment and gaming applications, notably known as the developer of Cookie Run. Devsisters utilizes instant messaging platforms such as KakaoTalk and LINE for its offerings.
Devsisters reported an operating loss for the second consecutive quarter on August 7, 2026, posting 52.7 billion won in revenue for Q2 2026 and contributing to a 33.3 billion won loss in the first half due to declining revenue and one-time costs. On July 30, the company globally released its deck-building auto-battler RPG, CookieRun: Crumble, which expanded its flagship intellectual property 'Cookie Run' into the idle RPG genre, tasking players with leading a Cookie army through collectible character progression, deck-building, and auto-battler combat while offering strategic depth despite its idle nature. Earlier on July 2, Devsisters rolled out the "Song of the Dragon Tongue" update for its mobile RPG Cookie Run: Kingdom, adding a new Dragon-grade character and a battlefield with changing rules, marking the second half of its continental-exploration arc. This followed the May 28 revelation of new starter decks and legendary pets for the CookieRun: Braverse Trading Card Game.
