Climate VCs who specialize: A Chat with AgFunder, Fifth Wall, and S2G Ventures’ Ocean Fund

Until recently, climate tech was either called “cleantech”,  and often bundled with “impact” investing, or buried within various categories and tech stacks. Since 2020, though, interest and investment in the category has surged. More VCs than ever branded themselves as climate tech specialists and many went further, focusing on just one or a very few sub-verticals. In 2022, 198 VC firms qualified for CTVC’s list of the “…core group of firms actively investing in climate tech theses,” up from 177 in 2021.  

But what do vertical specialist climate tech VCs know that generalists don’t? What are the benefits of specialization for their firms and portfolio companies, and what are the challenges of being so focused? At the SOSV Climate Tech Summit (Sept 26-27 / free & virtual), we turned to three prolific climate tech VCs for answers.

Founded in 2012, AgFunder specializes in food and agriculture, a climate tech space that raised nearly $30 billion last year. Highlights of AgFunder’s portfolio include MycoWorks, maker of mycelium leathers with $187M in funding (also backed by SOSV), Nobell, maker of plant-based cheese with $100M raised, and Atomo Coffee, which has raised over $50M to make coffee without coffee beans. The San Francisco-based firm also operates AgFunderNews, which has become an important source of analysis in this space. Rob Leclerc, PhD, Founding Partner of AgFunder, joined the panel.

Fifth Wall, a real estate tech VC, manages the world’s largest fund for the “built environment,” which accounts for up to 40% of global CO2 emissions. Founded in 2016, Fifth Wall has over $3.2B in AUM and estimates that its current portfolio will save 3 billion metric tons CO2e over its lifetime. In 2023 alone, Los Angeles-based Fifth Wall has joined a $96M investment in SPAN (smart electrical panels; featured in our Grid discussion) and led a $16M round for nZero (carbon management and accounting) and $300M raise for Our Next Energy Inc. (EV and grid energy storage). Greg Smithies, Partner at Fifth Wall, joined in.

S2G Ventures’ Ocean Fund is a division of Chicago-based S2G Ventures, a climate tech VC with $2B in AUM. It is among the first funds to focus exclusively on the so-called “blue economy.” The $100 million Ocean Fund has invested in three animal-free seafood companies—Avant Meats, The Plant Based Seafood Co., and Wildtype—as well as Brilliant Planet, which sucks up carbon with algae pools in the deserts (see last year’s carbon removal panel). Kate Danaher, Managing Director of S2G Ventures Ocean Fund, joined the discussion.

Katie Fehrenbacher, Climate Tech Deals Reporter at Axios, moderated this conversation.
