About At One Ventures
At One Ventures was founded in 2018 with a distinctive mission to apply a moonshot lab mindset to climate-positive investing. Based in San Francisco, the firm manages $60 million in assets under management and focuses exclusively on breakthrough technologies that can deliver significant environmental impact while generating strong returns.
The firm's investment approach targets seed and Series A companies working on transformative solutions in climate tech, deep tech, and agriculture. At One Ventures seeks out technologies that have the potential to create step-function improvements rather than incremental advances, embodying their moonshot philosophy. This includes investments in areas like synthetic biology, carbon utilization, sustainable materials, and precision agriculture.
At One Ventures has built an impressive portfolio of innovative companies including Air Company (carbon utilization), Geltor (bio-based materials), Pivot Bio (nitrogen-fixing microbes for agriculture), and Twelve (CO2 transformation). These investments demonstrate the firm's ability to identify and support companies developing breakthrough technologies that address climate challenges while building scalable businesses. The firm's concentrated focus and scientific rigor in evaluating deep tech innovations has positioned them as a go-to investor for climate tech entrepreneurs developing transformative solutions.

Fund History
- At One Ventures was formed in 2020 and launched Fund I in 2021 at $150 million.
- Fund II closed in October 2023 at $375 million, oversubscribed against an initial $250 million to $300 million target, which puts the firm above half a billion dollars raised across two vehicles in roughly three years.
- The Fund II limited partner base is unusual in its mix of sovereign, philanthropic and pension capital: GenZero, the Temasek-owned decarbonization investment platform, the World Wildlife Fund, the MacArthur Foundation, CalSTRS and the New Mexico State Investment Council.
- Both funds back early-stage companies whose technologies can reset the industries doing the most damage to natural systems, concentrated in buildings and construction, energy and transportation, and food and agriculture.
- The firm underwrites against what it calls the Triad: a disruptive deep technology that delivers radically better unit economics paired with radically better environmental economics, on the argument that climate returns and financial returns compound together rather than trade off.
