Martin Schweitzer
Managing Director & Founder
Martin Schweitzer

Martin founded 9inch Capital Partners in 2023 with a clear vision: build a lean, high-conviction micro fund-of-funds giving sophisticated European investors access to the world's best climate and deeptech fund managers.

His career spans Deutsche Bank, Erste Group, and CFO/deputy-CEO of Volksbank — bringing institutional investor experience, banking and entrepreneurship together. He also founded two start-ups himself, one of them eventually sold to Heineken.
