JASIKA Holding
JASIKA Holding was established in 2006 by Mirko Stemmler in Hamburg. The firm functions as the single family office for the Stemmler family. It preserves and deploys capital through property investments and related asset management. The firm allocates across real estate, private equity and infrastructure. Confirmed holdings include the Villa in Berlin-Mitte, Berlin Commercial Portfolio, Enderpark industrial site in Hamburg, BAREFOOT Hotel Timmendorfer Strand and Schkeuditz Logistics Properties. It also maintains exposure in ClimateTech, PropTech and Energy Transition & Renewables. Geographic reach covers Europe with additional activity noted in North America, Asia and the Middle East. Investment stages span development, early stage, late stage and value-add. AUM stands at an estimated 41 million USD. The team remains small with Mirko Stemmler as CEO and principal. Family shareholders Janine Endegrat and Silke Ulbrich-Käferlein each hold approximately 17 percent stakes. No additional offices are recorded. The firm partners with Beyond Real Estate Holding on select Montano Real Estate transactions. Ownership structure ties investment decisions directly to the founding principal and two family shareholders. This setup limits external mandates and keeps governance within the Stemmler family circle.
