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.

Canada's largest dedicated climate-tech seed fund with over $180M–$200M AUM. Operates a capital + talent model with shared talent hub for portfolio companies. Only backs business models where revenue growth is directly tied to climate outcomes and tracks tonnes of CO₂e mitigated as their north star metric. Founded by Mike Winterfield, formerly President of Randstad Professionals managing $300M in revenue.

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.

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.

Voyager is a climate tech fund that focuses on decarbonization technologies cheaper and higher-performing than fossil alternatives. The fund explicitly avoids companies dependent on subsidies or carbon credits while targeting 500 million tonnes of CO₂e impact per fund. The partnership combines deep operator experience—having founded six climate companies worth nearly $2B and structured $3B+ in climate financing—with a focus on infrastructure-heavy sectors like critical minerals, geothermal, and modular baseload systems.
