Onfintur

Onfintur was established to manage the personal capital of Urs Wietlisbach and Alfredo Piacentini, two of the three co-founders of Partners Group, the SIX Swiss Exchange-listed global private markets manager with over $140 billion in assets. The vehicle reflects the founders' decision to invest a portion of their substantial liquidity outside the institutional machinery they built, placing them among a small cohort of private-equity architects who operate parallel family investment offices. The firm is headquartered in Zurich. The office deploys capital across the full private-markets spectrum, mirroring the founders' deep asset-class fluency. Onfintur makes direct co-investments in private equity alongside external general partners, participates in venture and growth-stage rounds, and commits to real estate and infrastructure vehicles. The portfolio also includes allocations to private credit strategies. Confirmed positions are not systematically disclosed, though European venture and Swiss middle-market deals feature in the known footprint. The investment scope is global, with a natural concentration in European and North American developed markets. No public headcount or total deployment figure is available. The office does not maintain an external marketing presence and does not solicit third-party capital. Onfintur's posture is that of a minimalist, co-investor-oriented family office rather than a multi-family platform or a competing asset manager. The founders' operational attention remains with Partners Group, where both serve as non-executive board members, separating the family-office function from their ongoing governance roles at the listed firm. Structurally, Onfintur differs from most European single-family offices by virtue of its principals' continued, visible leadership in a major listed alternative-asset manager. This creates a permanent information and sourcing advantage — the founders see deal flow that few family offices can access — while maintaining a clean separation between institutional fiduciary money and personal household capital. The office operates without a disclosed CIO, suggesting that investment decisions remain closely held between the two principals.
