Mike Schroepfer splits his climate work into two clear lanes: he funds public-good research through philanthropy without expecting a return, and only invests in companies he believes can prove that low-carbon products are simply better or cheaper on their own, not because of their environmental benefit. Drawing on his years building data centers and infrastructure at Meta, he brings a hands-on, detail-focused approach to investing in physical systems, looks for industries where key costs are steadily falling, and connects the future of AI directly to the availability of cheap, clean power—all while still calling his broad mix of investments in energy, industry, and deep tech "climate" work, as long as each company's success also means less pollution and more resilience.
