## About

Founded in 1968, Saastamoisen Säätiö formalizes the philanthropy and investing of the Karttunen family. Karttunen. Five family members sit on the board today, with Chairman Petteri Karttunen also leading the Investment Committee alongside Kalvin and Anton Karttunen, while Päivi Karttunen chairs the Art Committee. The foundation partners with Aalto University and the University of Eastern Finland on science and education grants, but its capital base operates as a permanent endowment deploying across multiple asset classes. The foundation's investment strategy centers on buyout funds, complemented by direct holdings in Finnish timberland, global infrastructure funds, and mixed-use real estate — including the historic Syvänniemi Spool Mill site in Kuopio and a residential apartment in Helsinki's Design District. The endowment model supports both market-rate return targets and a substantial grant-making budget directed at Finnish science, art, and societal projects. The foundation is a member of the Finnish Venture Capital Association (Pääomasijoittajat ry), signaling active participation in the Nordic private equity ecosystem. Team size and total endowment value are not publicly disclosed. The foundation operates from Helsinki with no additional offices listed. Its principal non-financial asset is the Saastamoinen Foundation Art Collection, housed at EMMA–Espoo Museum of Modern Art — one of Finland's largest private contemporary art collections, actively loaned and exhibited internationally. The foundation's engagement with the Association of Finnish Foundations (Säätiöt ja rahastot ry) ties it into the broader domestic grant-making community. Saastamoisen Säätiö's distinction lies in its dual identity as an institutional limited partner and a commissioning arts patron — a structure that routes industrial wealth simultaneously into carried-interest-generating private equity commitments and long-term cultural infrastructure. Unlike a single-family office, it operates under Finnish foundation law, which imposes perpetual purpose constraints and public-benefit obligations on the capital.
