Summa Artium was established at the end of 2003 by the Soros Foundation with the aim of boosting sponsorship and support for the arts from the corporate and private sector and to promote the cause of arts and business partnerships and private support for the arts in general. In Hungary, profitable companies are legally permitted to devote up to 80 percent of the taxes on their profits to theatres and orchestras, paying only the remaining part to the state. Summa Artium mediates between the business sector and the art sector for 5 percent of the amount of the support given. The non-profit Foundation originally was meant to fill the gap the Soros Foundation left when it had ceased operating in Hungary.

In 2003, when Soros practically terminated the Hungarian Soros Foundation, András Török was a member of the board of curators. Soros then expressed his desire to keep a spinoff organization of the Foundation, and he provided a relatively modest sum for its launch. There was no one, however, with a plan to lead this organization until Török came up with an idea inspired by the London-based charitable organization Arts & Business, which mediates between the cultural scene and the private sector. Though Soros was skeptical about the model, he let it launch. The original budget was quickly spent, but the non-profit foundation manages to operate from market incomes.

In Török’s assessment, in a world in which the slogan "Big is Beautiful" was the defining paradigm, launching a non-profit foundation in order to help smaller projects survive demanded a nonconformist attitude. Summa Artium never received any state support, and Török is proud of this, as in Eastern Europe state involvement often involves symbolic or actual corruption. The Foundation is currently looking at possibilities to enhance community funding of the cultural sphere.
