Colossal Order was founded in the summer of 2009 by a group of game developers of the mobile game company
Universomo. Mariina Hallikainen was hired from outside of Universomo as the CEO of the new company. Investors thought that
Cities in Motion would not attract a large enough clientele. Instead of big investors, the first steps of the company were funded by Finnish public instruments –
Centre for Economic Development, Transport and the Environment,
Tekes, and DigiDemo finance of the Promotion Centre for Audiovisual Culture – as well as small private investors. In its early phase, the company was coached by the Yritystalli program of the
Tampere University of Technology, On 17 November 2025, Colossal Order announced that it had mutually decided to part ways with its publisher, Paradox Interactive, therefore ending their partnership in the
Cities: Skylines franchise. ==Games==
