3MER Partners has launched its debut fund with an undisclosed amount of capital to pursue stakes in late- and growth-stage companies and venture funds. The Zellik, Belgium-based firm spun out of Troismer, a multifamily office, in 2023.
3MER Secondary Fund leverages the firm’s network to acquire LP stakes in tech-focused venture funds and direct stakes in later-stage tech companies based in Europe, Southeast Asia and India. The fund is “capitalizing on proven success and current market trends” and aims to provide liquidity to LPs and holders of venture assets, according to its website.
3MER Partners is led by managing partners Leon Seynave, the managing director of Troismer; Thibaut Busschaert, an investment officer at Troismer; and Cédric Fonteyne de Vielcroix, a managing partner at the family office. 3MER Partners’ CFO is Filip Soenen, who also serves as the CFO of Troismer.
Troismer, headquartered in Belgium, was founded by Seynave in 2007 to provide investment management services to private individuals and families. Seynave previously served as chairman at London-based asset manager Stanhope Capital Group; co-founded private equity and real estate investor Mitiska; and co-founded Vente-Exclusive.com, a now-defunct online sales platform.
The family office invested in the $23 million Series B round of French data search and analysis developer Sinequa in 2019 and later exited when the company was acquired by data analysis platform ChapsVision for an undisclosed amount in 2024, according to data from CB Insights.
