SK Family Office

SK Family Office GmbH was established in 2011 in Karlsruhe. Alexander Ruis serves as managing partner alongside the founding family. The firm addresses succession, investment strategy, and philanthropy for multigenerational clients. Services center on private equity and real estate allocations with emphasis on energy transition opportunities. The firm restricts its client base to preserve individualized structures. All activity stays within Europe. No specific portfolio holdings appear in public materials. Team size and AUM remain undisclosed. The firm received Elite Report recognition each year since 2019. Alexander Ruis participates in the Lerbach Competence Circle. No operational events from the past 24 months are recorded. Independence from product sales forms the core structural difference. Advice stays separate from asset management or distribution activities.
