The All Aboard Fund
A collaborative climate fund
We close the “missing middle” financing gap in climate tech by backing 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 growth-stage climate ventures.
what we do
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.
Our Focus
We invest in companies tackling the most capital intensive sectors of the energy transition.
Our lens
Companies with large-scale emissions impact (>50 MT CO₂/year by 2040), credible FOAK readiness, and respected syndicate validation.
Our origin
The Fund emerged from All Aboard’s first annual convening of global climate investors in 2024.
Our founding backers unite around a shared mission: to help the best climate tech companies scale faster by bridging the capital gap.
