Sebrina Holdings
Nasrat Muzayyin started Sebrina Holdings in 1995. The firm grew from his earlier work at Concord Energy in physical crude oil trading and shipping. Wealth origin remains tied to those commodity and energy operations rather than any public listing or external fund raise. Deployment spans energy infrastructure, direct real estate ownership and venture commitments. The office holds multiple Singapore residential properties including Astrid Hill and Narooma Road bungalows alongside mixed-use assets such as Mohamed Sultan Road shophouse. It also maintains an oil and gas trading portfolio and a transportation fleet in North Dakota and Colorado. Geographic reach covers Asia, Europe and North America. Co-investors include professional racing driver Rui Aguas on motorsport assets and architect Ko Shiou Hee on real estate projects. Stage focus sits in growth and late-stage opportunities executed through direct co-investments and SPVs. Team size and total deployment figures remain undisclosed. Additional offices are not listed. Philanthropic vehicles include the Nasrat Muzayyin Professorship in Medicine and Technology and the Sebrina Holdings Endowed Scholarship at Singapore Management University. No operational events from the last 24 months appear in public records. The office maintains membership at the Rajpruek Club in Thailand. Governance stays inside the founding family with external partners limited to specific project execution rather than broad LP-style capital raises.
