Barclaycard Arena (former Color Line Arena) project was inspired by Hartwall Arena and initiated by a group of Finnish investors, for example Lemminkäinen and Sanoma.

Mika Sulin was key contributor of the successful execution of the project during the design, finance, build, own and operate phases. The project was fully executed by Finnish ecosystem partners. Mika was also acting as the first managing director of the arena and sold all naming and marketing rights related to it.
