Gamenauts is an independent game development studio based in Silicon Valley and founded in September 2005 by Stanley Adrianus, formerly of Yahoo! Games.
Their 2011 game Ninja Fishing has been criticized as copying the game mechanics of Radical Fishing by Vlambeer. In 2013, Vlambeer published Ridiculous Fishing, with the highest rated reviews of the year.
In 2012, the company announced a publishing initiative for indie Asian developers, signing up studios from South East Asia such as Kurechii Studio, Menara Games, Artlogic Games and Nerdook Productions to publish their mobile titles for the worldwide market.
