Touchstone Partners is an early-stage Vietnam-focused VC that applies a final filter to every deal asking "If this startup succeeds, what difference will it make to Vietnam or the world?" and operates as a rare local VC acting as a gateway for foreign climate-tech startups into the Vietnamese market through programs like the Net Zero Challenge competition co-run with Temasek Foundation. The fund builds and runs ecosystem programs including Vietnam's largest climate-innovation competition and the country's first energy efficiency startup accelerator, while operating a dedicated $10M Green Transition Fund that uses competition sourcing to provide catalytic capital to both domestic and global teams piloting climate solutions in Vietnam.
