Colossal Biosciences is a biotechnology company focused on de-extinction and genetic engineering, aiming to revive extinct species using CRISPR technology and involved in conservation efforts.

Prelude Ventures manages capital exclusively for the climate-focused Simons family, creating a single-LP structure that demands strict venture returns from a 100% climate portfolio while applying a hard "no fossil fuels" rule that rejects any technology making oil, gas, or coal extraction cheaper or longer-lived. The firm combines deep technical operating experience with climate activism roots and has invested continuously through climate tech's "dark years" since 2009, positioning itself as a climate generalist comfortable with high capital intensity and long hardware timelines across the entire low-carbon economy.

Leads deep-tech, hardware-heavy climate investments across cutting emissions, carbon removal, and time-buying solutions, backing nonprofit research and offering in-house scientific expertise plus hands-on technical, hiring, and regulatory support.

Energy Impact Partners invests from seed to pre-IPO, giving founders direct access to utility operator decision-makers and internal research mapping pain points and co-designing customer-backed theses for hardware-heavy grid and industrial decarbonization. Built around a coalition of large utilities and energy companies that actively collaborate to give portfolio companies direct access to decision-makers across dozens of operators, with an internal research team mapping utilities specific pain points and co-designing investment theses. The firm covers the full climate capital stack from seed to pre-IPO plus venture debt, deliberately focusing on hard, capital-intensive segments like grid resilience and industrial decarbonization.

Clean Energy Ventures funds disruptive, capital-light technologies and business model innovations that reshape how we produce and consume energy. Since 2005, the leadership team has invested in 40+ climate tech startups with the potential to substantially reduce greenhouse gas emissions by 2050. The firm requires every investment to demonstrate 2.5 gigatons of CO2 mitigation potential using their proprietary calculator. More than 60% of the investment team holds advanced science or engineering degrees to provide hands-on technical support. Their track record includes only ~15% write-offs in hardware-focused cleantech, unusually low for a sector where 90%+ of post-2007 funded companies failed to return capital.

Early-stage climate investor using a 12,000+ startup proprietary database and hedge-fund-style quantitative screening instead of relationship sourcing, often taking board seats (96%) and offering Rocky Mountain Institute sector expertise.
