New System Ventures positions itself as a systems-level research firm that looks for turning points in overlooked parts of the energy transition, tying its investments to energy security and reindustrialization rather than decarbonization alone, and it invests from a company's earliest stages through Series B, sometimes helping build companies from scratch by combining venture, growth, project finance, credit, and policy support for capital-intensive hardware and infrastructure startups. Its portfolio reflects this focus on hard infrastructure problems, including high-temperature superconducting wire, industrial heat storage, critical-mineral recovery, transferable tax-credit infrastructure, transformer sourcing, and ultra-high-temperature geothermal drilling technology.
