Proprius Partners and Certior Capital merging to form a specialised asset manager with more than EUR 500 million assets under management
Press release 15 September 2026
Proprius Partners Ltd has agreed to acquire the business operations of Certior Capital Ltd. Under the arrangement, Certior Capital’s business will become part of Proprius Partners. Together, the companies will form an independent European-focused asset management firm with more than EUR 500 million assets under management and approximately 20 employees.
Certior Capital is a Finnish alternative investment fund manager specialising in European private equity and private credit. Certior’s funds total more than EUR 300 million in size. Over its history, the company’s funds have made investments totaling more than EUR 500 million.
Following closing of the transaction, Certior Capital will continue to operate under its own brand as part of Proprius Partners. Certior’s team will retain its investment independence, focusing on its established investment strategy. Certior’s personnel are committed to the long-term development of the business as part of Proprius Partners. Together, we will continue to seek alpha-generating opportunities, specialising in the most inefficient parts of the markets.
Complementary investment expertise
The strategic rationale for the arrangement is to bring together the expertise of two complementary investment organisations under one combined entity. We see potential in combining Proprius’ listed markets expertise with Certior’s private markets expertise. Certior’s long-standing relationships within European private equity markets and its extensive network built over many years will open new opportunities for the combined entity to identify investment opportunities, pursue co-investments and develop new client solutions.
The transaction strengthens Proprius Partners’ position as an independent and entrepreneur-led asset manager in a market where consolidation has accelerated in recent years. Increased scale, broader investment expertise and a more diversified product offering support Proprius’ ability to grow independently and serve its clients even more comprehensively.
Niko Fagernäs, CEO of Proprius Partners, says: ”Certior has built a strong position in European private equity and an extensive contact network that would take years to build. Through this arrangement, we bring top expertise from both listed and unlisted markets under the same roof. This is a significant step in Proprius’ development and strengthens our position as an independent asset manager focused on European investing. Simultaneously, it is important for us to maintain the entrepreneurial spirit, agility, and strict investment focus of both organizations.”
Timo Hara, founding partner of Certior Capital, comments: “Certior and Proprius share a long-term investment philosophy, an entrepreneurial way of working and a strong focus on the European investment market. We have similar values, emphasising investment-led thinking and analytical rigor. Certior will continue under its own brand with its existing team and focus on its own investment strategy as part of a larger and more diversified firm. We believe this will open new opportunities for our clients, our investment activities and our personnel.”
Ari Jauho, founding partner and Chairman of Certior Capital, states: “Proprius is a logical partner for us in Certior’s next phase of growth. Together with Proprius, we can combine Certior’s existing expertise, team and operating model into a stronger combined entity and support the long-term development of the business. We are highly excited about our shared future and what we can build together for the benefit of our clients.”

Completion of the transaction is subject to approval by the Finnish Financial Supervisory Authority and the fulfilment of other customary closing conditions. The transaction is expected to be completed in January 2027.
The financial terms of the transaction will not be disclosed.
