B-Flexion Fund Management manages assets for the Bertarelli family, whose wealth stems from the $13.3 billion sale of biotech firm Serono to Merck.
B-Flexion Fund Management (Jersey)
B-Flexion Fund Management (Jersey) was established as a regulated investment entity in the Channel Islands, forming one piece of the broader B-Flexion group that oversees the investment affairs of the Bertarelli family. The wealth originates from Serono, the Swiss biotech company founded by Ernesto's father, which Merck acquired in what remains one of the largest cash transactions in European pharmaceutical history. Since that exit, the family has institutionalized its capital management through structures spanning Geneva, London, Luxembourg, and Jersey — with B-Flexion Fund Management acting as the regulated fund platform for certain pooled and managed vehicles. The firm deploys capital across a genuinely multi-asset mandate. Public disclosures and fund filings indicate positions spanning public equities, private equity, venture capital, and real assets. Within private markets, the focus leans toward life sciences and healthcare innovation — an area of demonstrable family expertise — alongside technology, consumer, and select infrastructure plays. The vehicle structure has historically included both direct co-investments alongside external managers and commitments to third-party funds, offering flexibility in how exposure to each sector is built. Scale remains opaque. Neither the AUM within the Jersey entity nor the broader Bertarelli family fortune is publicly disclosed. The Jersey Financial Services Commission regulates B-Flexion Fund Management (Jersey), which suggests a professionalized operation with third-party capital or pooled family vehicles rather than a pure single-family office. The group also maintains B-Flexion Advisory (Luxembourg) and the Waypoint Capital platform, indicating a multi-jurisdictional architecture typical of European family offices managing complex cross-border wealth. Structurally, what distinguishes the B-Flexion setup is the deliberate interplay between a Geneva-anchored family office, a London-based asset manager, and a Luxembourg advisory entity — creating a capital-deployment architecture that separates strategic asset allocation from fund structuring and regulatory oversight. This design, while not unique among large European family offices, reflects a governance approach where the Jersey entity serves as the regulated access point for external managers to receive family capital through institutional-grade fund vehicles.

Frequently asked questions
What is the relationship between B-Flexion and the Bertarelli family?
B-Flexion Fund Management (Jersey) is the regulated asset management entity within the broader B-Flexion group, which serves as the investment organization for Ernesto Bertarelli and his family. The Bertarelli wealth was generated from Serono, the Swiss biotechnology company founded by the family and sold to Merck KGaA in 2006. The group maintains multiple entities across Europe, with the Jersey fund manager handling regulated fund activities.
Is B-Flexion a single family office or an asset manager open to external capital?
The Jersey Financial Services Commission regulates B-Flexion Fund Management (Jersey), which implies the structure can manage pooled vehicles or third-party capital in addition to family money. The broader B-Flexion group, however, was built to institutionalize the Bertarelli family's wealth rather than to operate as a commercial asset gatherer. The exact mix of proprietary family capital versus external investor commitments is not publicly disclosed.
What is B-Flexion's relationship to Waypoint Capital?
Waypoint Capital and B-Flexion operate as distinct but related entities within the Bertarelli family's investment ecosystem. Waypoint Capital is often described as the family's Geneva-based investment adviser, while B-Flexion entities handle fund management and structuring functions in regulated jurisdictions including Jersey and Luxembourg. Together they form a multi-jurisdictional architecture for deploying family capital.
Does B-Flexion invest directly or through external fund managers?
The firm appears to use both approaches. Available public disclosures indicate a mix of direct co-investments in private companies, particularly in life sciences and healthcare, alongside commitments to external fund managers for other asset classes and geographies. The regulated Jersey structure allows the group to access institutional-grade fund vehicles managed externally.
How large is B-Flexion's AUM?
B-Flexion does not publicly disclose assets under management. Media estimates of the Bertarelli family fortune derived from the Serono sale and subsequent investments have varied over time, but no verified figure for the Jersey entity exists in public filings. Institutional counterparties typically receive this information through direct due diligence.
