All Aboard Fund is a climate technology venture co-investment manager helping promising technologies cross the financing gap between successful pilots and large-scale commercial deployment. It works with a coalition of specialist climate investors to back scale-ready companies alongside a lead investor on the same terms, using shared diligence rather than replacing the lead investor. Its portfolio includes Zanskar, which applies AI to geothermal discovery and development; Terra CO2, which makes low-carbon cementitious materials; and Antora Energy, which stores renewable electricity as industrial heat in carbon thermal batteries. The fund is distinct from the coalition’s member firms and their combined assets.

All Aboard Fund I$133M
Inaugural climate venture co-investment fund at US$133 million final close, backing scale-ready energy transition technologies between successful pilots and broad commercial deployment. Investments are made alongside a coalition of climate investors on the same terms as a lead investor. The manager names Zanskar, Terra CO2 and Antora Energy as the first three investments. Its own newsroom dates the earliest final-close headline August 11, 2026; its explicit final-close post was published August 21. The former US$300 million target and coalition members’ combined assets are not the fund’s closed capital.
