Investment thesis

SeaX Ventures invests globally in early-stage deep-tech startups working on 'exponential' technologies that can transform societies and drive economic progress. Its focus areas include healthtech, biotech, AI infrastructure, advanced materials/nanotechnology, climate tech, physical AI, space tech, and quantum. The firm leverages a strong network across the U.S. and Asia, with LPs consisting of major regional corporations and family offices, and ties to affiliate company RISE and its 2000+ startup alumni. Through its '3As' approach (Access, Accelerate, Advantage), SeaX connects portfolio companies with corporate partners and co-investors, positioning itself as a bridge between Silicon Valley and Southeast Asia to help founders build audacious global companies.
