Sigrid Jusélius Foundation
Finland's largest private medical research funder deployed EUR 28M in 2025, backed by Nordic real estate and timberland.
Sigrid Jusélius Foundation
Fritz Arthur Jusélius established the Sigrid Jusélius Foundation in 1930, naming it for his daughter. It has since become Finland's largest private funder of medical research, awarding grants to individual researchers and collaborative programs. The foundation's wealth originates from Jusélius's personal fortune but the present-day corpus is sustained by a diversified asset base that includes commercial, mixed-use and residential properties in Helsinki and Stockholm, along with forest and plot funds across Finland. The foundation directs capital almost exclusively to basic and translational medical research. In 2025, it awarded EUR 28 million — a deployment level that makes it one of the most significant non-state medical research grantors in the Nordics. Funding flows to individual researchers, research groups and joint initiatives; known partners include the Jane and Aatos Erkko Foundation and the Finnish Medical Foundation, with whom it co-founded the Brain Gain/Brain Import program to attract top-tier medical researchers to Finland. The foundation also maintains a dedicated research fund at the University of Helsinki and collaborates with the Knut and Alice Wallenberg Foundation on external evaluation of grant applications. The foundation operates with a lean structure typical of European medical endowments. Day-to-day portfolio management and grant administration are handled by a small team in Helsinki. The foundation's 2025 annual report notes a deliberate shift toward a more active role on the science side — building researcher networks and shaping research agendas — while the investment and real-asset base continues to deliver steady income for grant-making. No alternative vehicles or co-investment clubs are publicly disclosed. The Sigrid Jusélius Foundation stands apart from peer Finnish endowments through the laser focus of its mandate: all dispatchable resources flow to medical research, with no other charitable pillars. The portfolio is real-asset-heavy by design, generating predictable income streams from Nordic property and timberland. A public-facing art collection and a mausoleum in Pori anchor the foundation's cultural legacy, but neither distracts from a single-mandate grant engine that funded EUR 28 million in science during a volatile 2025.

Frequently asked questions
Who runs investment decisions at the Sigrid Jusélius Foundation?
The foundation does not publicly name its investment staff. The endowment is managed conservatively with the goal of producing stable, long-term income for grant-making. Real estate holdings (Helsinki, Stockholm) and Finnish forest assets form the core of the portfolio.
Does the Sigrid Jusélius Foundation invest in external funds or only direct assets?
The foundation's public reporting emphasizes direct ownership of real estate and forest land. It does not disclose commitments to private equity, venture capital or hedge funds through its website or annual reports.
Which medical fields does the Sigrid Jusélius Foundation prioritize?
The foundation supports basic and translational medical research across all disease areas. Its signature programs include the Brain Gain/Brain Import initiative, co-founded with the Jane and Aatos Erkko Foundation and the Finnish Medical Foundation, which funds recruitment of top-tier medical researchers to Finnish institutions.
Is the Sigrid Jusélius Foundation a single-family office?
No. The foundation is a Finnish medical research endowment, legally and operationally distinct from any family office. Although founded by Fritz Arthur Jusélius using family wealth, it has no family members on its publicly listed operating team. Its governance follows Finnish foundation law.
How does the foundation source its grant recipients?
Applications are peer-reviewed by panels of international medical experts. In an unusual collaboration, the Knut and Alice Wallenberg Foundation assists in evaluating grant applications using its own network of foreign scientific reviewers.
Does the foundation co-invest with other Nordic endowments?
There is no public evidence of co-investment activity. The foundation's balance sheet is dominated by directly held Finnish and Swedish real estate and timberland, not commingled fund positions.
What is the foundation's known posture on operating costs versus grant outflows?
The foundation does not publish detailed cost ratios. However, its 2025 annual report indicates a EUR 28 million grant outflow — a figure that, relative to Nordic peer endowments, suggests a high payout rate and a lean operating structure.
