Investment thesis

At One Ventures backs early-stage companies using disruptive deep tech to upend the unit economics of established industries while dramatically reducing their planetary footprint. Their formalized 'Triad' thesis requires portfolio companies to simultaneously deploy disruptive deep technology (wins on physics fundamentals—matter, energy, time, and space), achieve fundamentally transformed unit economics (cutting costs by more than 3x the margin of the incumbent industry), and drive strong climate- and nature-positive outcomes. The firm targets the industries with the largest planetary footprint—agriculture & food, manufacturing, buildings, energy generation, energy storage, and transportation—and seeks companies whose superior economics make adoption a 'no-brainer,' ensuring environmental impact scales with commercial success. With 70% of portfolio companies in North America and 30% internationally, At One manages over $525M across two funds and provides hands-on support in talent, operations, manufacturing, marketing, and IP strategy.

Notable quotes

We're not touching green premiums with a 50-foot pole. In fact, parity is not a thing either, right? Parity dies because of capex inertia. If we created a venture firm where, yes, it's all about the planet, but literally everything is not just the less expensive way to do it, but a radically less expensive, empowered by breakthrough technology, that could lead to just as rampant adoption, a rampant pull.

If you're trying to collect carbon dioxide in the air, it's like trying to suck all the carbon dioxide through a tiny soda straw. These are deep, physical disadvantages to the approach. We're going to invest in the companies that make it possible to go do that at incredibly low cost structures.

That's why we invested in Ascend Elements, an advanced materials company that recycles end-of-life lithium-ion batteries and reintegrates the recycled metals directly into EV batteries. With stronger unit economics and similar cathode material performances, they make it an obvious choice for EV automakers to adopt the solution, driving faster positive environmental impact.
