Ramphastos Investments

Ramphastos Investments was established in 1994 by Marcel Boekhoorn. He built the firm after early exits including the sale of mobile operator Telfort. The office manages capital generated from those transactions and later holdings in HEMA and High Tech Campus Eindhoven. The firm pursues buyouts, growth equity and early-stage investments. It takes majority stakes and works directly with management on revenue initiatives, marketplace expansion and internationalization. Confirmed holdings include High Tech Campus Eindhoven, Mazarine Energy, The Antenna Company, SKS365 and Novum Bank. Positions span the Netherlands, other European markets and selected energy assets outside the continent. The team numbers twenty professionals. Additional offices operate in Amsterdam. Adjacent holdings include Ouwehands Dierenpark in Rhenen and Hotels van Oranje. No operational events from the last twenty-four months appear in public records. Ramphastos operates as a single-family office that invests only its own capital. This structure allows it to pursue control positions and special situations without external fund timelines or LP reporting requirements.
