Prime Movers Lab

Prime Movers Lab Research Investment Thesis Prime Movers Lab is the world's leading venture capital firm dedicated exclusively to breakthrough science and deep technology innovation. Founded in 2018 by Dakin Sloss, an entrepreneur with a track record of creating billions in enterprise value, the firm invests in companies founded by "Prime Movers"—serial entrepreneurs and inventors who are tackling the world's most pressing problems. The firm's core investment philosophy centers on the belief that "the least useful thing we provide is capital," emphasizing hands-on operational support, technical expertise, and deep domain knowledge alongside financial investment. The firm explicitly positions itself as a partner to founders rather than a traditional passive investor, providing intensive support including weekly partner calls, executive coaching access, and leveraging a PhD-heavy technical team to help navigate complex scientific and engineering challenges. Sector & Industry Focus Prime Movers Lab focuses exclusively on breakthrough scientific innovation across six primary verticals: Energy : Advanced battery technologies, fusion energy, energy storage systems, and renewable energy infrastructure Transportation : Supersonic and hypersonic aircraft, autonomous electric aviation, and advanced mobility solutions Infrastructure : Space transportation, satellite constellations, orbital infrastructure, and cislunar development Manufacturing : Advanced materials, 3D printing, nano-structured materials, and manufacturing automation Human Augmentation : Brain-computer interfaces, prosthetics, longevity technologies, and medical therapeutics Agriculture : Sustainable agriculture technology and food systems innovation The firm explicitly avoids consumer applications, pure software, and traditional B2B SaaS. Instead, it focuses on hard technology companies that have completed core science de-risking and are ready for scaling. Stage Focus & Check Size Prime Movers Lab operates across three primary stages: Seed Stage : $2M-$5M investments for teams with validated technology and initial proof-of-concept Series A : $5M-$30M investments for companies demonstrating product-market fit Growth/Scale : Selective investments in later-stage portfolio companies through dedicated growth funds Typical check size ranges from $2M to $30M, with the firm targeting 15-25% ownership stakes.
