All Aboard Fund

A unique fund designed to turn the valley of death into a valley of opportunity.

The All Aboard Fund is a collaborative venture capital fund designed to close the “missing middle” financing gap in climate tech.
We back high-potential companies at the scale-up stage — where capital needs outpace early venture appetite, and risk limits later-stage investment.
Our investment model is simple: we co-invest alongside a pre-approved group of top-tier VCs, growth equity, and infrastructure investors. When they commit, we do too.
We provide streamlined, passive co-investment into FOAK and growth-stage climate ventures.
Our process enables syndicates to close faster, with more capital, and gives founders access to our high-value partnership platform.
We are a flexible, conviction-led fund designed to help the best ideas in climate tech scale.
We crowd capital into the most likely technology leaders.
We invest in companies tackling the most capital-intensive sectors of the energy transition, including:
 Clean hydrogen
 Advanced nuclear
 Carbon capture
 Long-duration storage
 Geothermal
 Biofuels
 Marine decarbonization
 Agriculture
 Nature-based solutions
Our lens: companies with large-scale emissions impact (>50 MT CO₂/year by 2040), credible FOAK readiness, and respected syndicate validation.
The All Aboard Fund emerged from a convening of global climate investors hosted in 2024.
Our founding backers include leaders from TED, Khosla Ventures, Arnold Ventures, and Partners Capital—united around a shared mission: to help the best climate tech companies scale faster by bridging the capital gap.
