The "Foundation Tönissteiner Kreis" was set up in 2005. The Foundation is an independent legal entity. 83 members provided initial donations and further amounts have been received by members ever since. The aim is to build up a capital base in the medium term which will produce sufficient surplus to support the project work of the group significantly in supporting the international young leadership pool in Germany.
Since 2006 the Foundation awards the Tönissteiner Prize distinguishing one or two outstanding projects of the Studierendenforum. An article about the first Tönissteiner Prize 2006 appeared in the Stifterverband Magazine. Furthermore, in 2009 the Foundation set up a travel grant fund to promote the realization of generational dialogue and to allow the younger generation to attend to Tönissteiner activities by subsiding travel costs.
