The developer is closely linked to Swedish publisher Paradox Interactive,[7] which tests, markets, sells, distributes, and owns the intellectual property of all games by Colossal Order.

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.

[7] In its early phase, the company was coached by the Yritystalli program of the Tampere University of Technology,[8] but advice was sought directly from experienced Finnish game development companies as well, specifically Remedy Entertainment and Frozenbyte.

Colossal Order has the freedom to create games without limitations set by the publisher, bar those on schedules.

Cities: Skylines II was announced on March 6, 2023 and released on October 24, 2023 for Windows.
