Investment thesis
SeaX Ventures backs early-stage companies working on 'exponential' deep-tech technologies capable of transforming societies and driving economic progress. Its focus spans healthtech, biotech, AI infrastructure, advanced materials and nanotechnology, climate tech, physical AI, space tech and quantum, while remaining open to other frontier areas. The firm invests globally with particular emphasis on bridging Silicon Valley and Asia, using its knowledge of both markets to identify and support ambitious founders. Its LPs include some of the region's largest corporations and family offices, and the fund leverages those relationships plus its affiliate RISE's network of startup alumni and corporate partners to give portfolio companies strategic access and acceleration.
