GV invests in technology and life-science companies, including AI applications, developer tools, cybersecurity, computing infrastructure and healthcare.
Its AI interests span the stack: new computing systems and inference infrastructure, tools for developers, software for professional workflows and applications in drug discovery and patient care. This gives both infrastructure founders and application builders a route to a specialist investment team.
GV developed the design sprint, a five-day process that takes a business question through problem definition, prototyping and customer testing. Its published sprint materials help teams test demand and product decisions before committing to a full launch.
