What At One Ventures does
At One Ventures, L.P. is a privately held venture capital firm, founded around 2018 and domiciled in California, that invests seed capital in climate tech and deep tech companies with the stated mission of making humanity a net positive to nature. The firm organizes its investment thesis around four verticals — Air, Water, Soil, and Biodiversity — and targets disruptive deep-tech businesses capable of upending the unit economics of established industries while reducing planetary footprint. Its underwriting edge is its operator-investor bench: Founding and Managing Partner Tom Chi is a physicist and former founding member of Google X (Google Glass, early self-driving car program) with prior roles at Microsoft and Yahoo Search, supported by partners from BASF, SRI International, Baird Capital Partners, and FINCA Impact Finance, and full-time functional experts covering Talent, Operations, Marketing, IP/Patent Strategy, and Manufacturing. The firm does not sell a product; it makes money via traditional VC economics — management fees on committed capital and carried interest on portfolio exits — sourced from undisclosed Limited Partners and accessed through an Ark-hosted investor portal. Recent disclosed portfolio activity (mid-2024 through early 2026) includes Blue Energy (shipyard-manufactured nuclear power), Stellaria (molten salt nuclear, France), Factor2 Energy (supercritical CO2 geothermal), Near Space Labs (stratospheric imagery), Provectus Algae (methane-reducing feed supplements), Prefer (fermentation-based coffee/cocoa), Miraterra (soil sensing, with the Trace Genomics acquisition), Cuby Technologies (transportable construction factories), and Addis Energy (subsurface hydrogen/ammonia). The firm is small (1-10 employees), with headquarters in Menlo Park, California, and a globally distributed deal-flow footprint across North America, Europe, Africa, and Asia-Pacific.
