First Checks for Big Ideas: A Conversation on Early-Stage Climate Tech Funding with SOSV, At One Ventures, E²JDJ, and Material Impact

Each year at the SOSV Climate Tech Summit (Sept 26-27 / free & virtual), we invite leading VCs to join our classic panel on early-stage climate tech investing. And we ask all the questions. Who are they writing checks to and why? Which climate technologies are underrated, which are overrated, and which are just emerging?  

After years of strong  growth in climate tech investing, 2023 is already turning out to be a tough one. Total investment in 1H 2023 is down 40% year-on-year,  according to CTVC,  but seed investments over the same period grew 23%, which tells the familiar story that later stage is where there’s a lot of pain.

Luckily for them, our four panelists are writing those pre-seed and seed checks,  and they have to be wondering how their young startups will fare in this new investing climate, so to speak. Here are the four firms and partners that participated: 

SOSV is a deep tech fund focused on planetary and human health with over 100 investments in climate technology (see the SOSV Climate Tech 100). Its portfolio includes alt-protein unicorns Upside Foods, Perfect Day, and NotCo, all of which graduated from SOSV’s IndieBio startup program. Dr. Pae Wu, General Partner at SOSV and CTO at IndieBio, joined the panel. 

E²JDJ, based in New Orleans, backs startups that transform the computation, biology, physics, and chemistry of food production. The firm has invested in NovoNutrients (an IndieBio graduate), which uses microbe bioreactors to convert CO2 into food and animal feed, and Perfeggt, an innovator of plant-based eggs based in Berlin. Founding Partner Stephanie Dorsey represented E²JDJ on the panel.

Boston-based Material Impact builds deep tech companies powered by material science. Its investments include SOURCE, which purifies drinking water using only sunlight and air, and Maglev Aero, developer of an all-electric vertical-takeoff and landing (VTOL) aircraft for passengers and cargo. Corinna Chen, Partner at Material Impact, joined the panel.

At One Ventures, based in San Francisco, is a climate specialist focused on food and agriculture, built environment, energy and transportation, and ecosystem restoration. It has invested in Finless Foods (another IndieBio grad), developer of plant-based and cell-cultured seafood, as well as Dendra Systems, which uses drones to plant trees and restore habitats. Laurie Menoud, Founding Partner at At One Ventures, discussed the firm’s approach to first checks.
