GISMA Business School is a privately-owned business school in Germany with its main site in Hannover and a branch in Berlin. It was launched in September 1999 as a joint initiative by the German state of Lower Saxony and several large private-sector companies that were based there. In financial difficulty after its partnership with Krannert School of Management ended, GISMA was rescued from bankruptcy when it was bought by the for-profit education company Global University Systems in September 2013
