Lemantrust
Lemantrust was founded by the Muller family. It operates as an independent multi-family office licensed by FINMA and provides wealth management, estate planning, and succession services. The firm deploys capital through fund-of-funds commitments, direct co-investments via SPVs, and philanthropic structures. Confirmed positions include board representation at ACE & Company SA and Checkout.com. It maintains exposure to Swiss real estate and has sponsored FIA Formula E. Allocations span Europe and target a 10-year horizon with openness to emerging managers. Lemantrust employs no disclosed headcount figure. It maintains membership in VSV-ASG and works with auditors BDO SA and former auditor PricewaterhouseCoopers SA. The firm runs an internal philanthropic advisory vehicle that has supported ETH Zurich Foundation and ISREC Foundation. No operational events from the last 24 months appear in available records. Lemantrust functions as both allocator and operating platform through its principals' board seats at multiple Swiss financial services firms. This hybrid structure allows direct oversight of client capital alongside external fund commitments.
