Founded by Hans F. Olsen, United Coders began its activities in 1987. In the beginning, the company was simply a gathering of enthusiastic hardcore programmers and pixel pushers, who developed games and multimedia applications for the Amstrad CPC, Commodore 64, and the Amiga platform. In 1993, United Coders officially registered as a company. During 1993-1995, United Coders developed and marketed a number of software applications for the Amiga - amongst these the highly acclaimed Amiga First Aid series of applications. By the end of 1995, United Coders achieved certification as official member of the exclusive Amiga Developers Support Program Europe (A.D.S.P.E).

During the first quarter of year 2000, United Coders changed focus and transitioned itself into a highly specialized PR-agency focusing on servicing developers, publishers and distributors within the games and multimedia industry. United Coders offered services such as media contact, press releases, newsletters, articles, company profiles, advertisements, localization and product evaluation. By the end of year 2003 United Coders had an extensive network of industry contacts throughout Europe (Nordic in particular), and it is safe to say that United Coders had successfully become the leading games industry PR-agency in the Nordic region.

In April of 2004, United Coders relocated to San Francisco and returned to its roots, and immersed itself into a privately owned third party contract game development studio committed to design, create and develop state-of-the-art computer games. Since relocating to San Francisco, United Coders has worked on a number of titles on PC, X-Box Live Arcade, Game Boy Advance, Nintendo DS and Nintendo Wii. Most recently, United Coders has completed work on the world famous Dragon's Lair franchise on the Nintendo DS, with a Sony PSP version to follow in 2008.
