The All Aboard Coalition has closed its inaugural fund at roughly $133m, less than half of its $300m target, according to reporting by New Private Markets.
The London-launched coalition brings together climate and deep tech investors to co-invest in companies building their first commercial-scale plants, a stage often described as the "missing middle."
It was co-founded last year by former TED curator Chris Anderson and Stan Miranda, founder of Partners Capital. The fund co-invests alongside member firms, matching their cheques when at least three coalition members back a deal.
Members include Al Gore's London-based investment firm Just Climate, Bill Gates' Breakthrough Energy Ventures, Khosla Ventures, DCVC, and Clean Energy Ventures.
All Aboard has already begun deploying, backing geothermal developer Zanskar and green cement startup Terra CO2 earlier this year.
Three firms recently joined the coalition, according to a LinkedIn post published by All Aboard last week: Activate Capital, G2 Venture Partners and Lightrock.
