KIZOO Technology Capital

Karlsruhe, Germany·Founded 2007··kizoo.com

KIZOO Technology Capital is a Karlsruhe-based evergreen venture investor founded by internet entrepreneur Michael Greve. Structured as a family-equity vehicle within Mira Holding, it invests off its own balance sheet without external LPs. Since founder Greve launched the Forever Healthy Foundation in 2015, KIZOO has focused exclusively on rejuvenation and longevity biotech, providing seed and follow-on capital to companies developing therapies that repair or reverse age-related cellular damage. In 2021 Greve committed an additional EUR 300 million (about USD 362 million) to build out this portfolio. KIZOO also retains large legacy stakes in German internet and SaaS companies it seeded in its earlier IT era, including Babbel, Mambu and Staffbase.
