What Qmulus does

Qmulus is a single family office headquartered in The Hague, Netherlands, employing a dedicated team of 20 professionals. The firm manages a diversified investment portfolio with a primary focus on U.S. markets, emphasizing absolute return strategies, and extends into direct real estate investments and majority or minority equity stakes in a select number of companies. As a single family office, Qmulus operates exclusively with proprietary capital and has no external investors or client mandates, which enables long-term positioning independent of capital cycle pressure. The firm's central operating philosophy, "Simplicity is Beautiful" (Eenvoud is Mooi), emphasizes disciplined, essential decision-making over complexity.

Qmulus's wholly-owned subsidiary, Qliq, is a systematic quantitative proprietary trading firm based in Amsterdam that trades derivatives across multiple asset classes in U.S. markets, with stated plans to expand into other regions. Qliq's trading is fully systematic and fully automated, operating deliberately in the mid-frequency space rather than competing on high-frequency or low-latency dimensions. Algorithms run on signals developed through years of research, with AI actively integrated across research, systems, and day-to-day operations to support signal generation, strategy optimization, and predictive analytics. The firm operates Qliq as an internally funded hedge fund with no external investors, providing full strategic independence.

Qmulus also operates the Cirrus Foundation, a wholly-owned nonprofit entity supporting charities focused on climate, human rights, and combating polarization. Revenue mechanics for the consolidated entity are derived from investment returns, capital appreciation, real estate yields, dividends from portfolio companies, and proprietary trading gains; specific revenue figures are not publicly disclosed. Go-to-market is effectively internal: there are no external customers, no client mandates, no consumer-facing products, and pricing or fees do not apply to this capital-management structure.
