Led by former TED head Chris Anderson, the coalition’s fund is designed to help climate technology companies finance the costly step from early development to their first commercial-scale facilities—a gap often called the “valley of death.” It does so through coordinated equity co-investment, not project loans.
What the “valley of death” means for climate technology
Early venture capital can support a company as it develops a technology and demonstrates that it works. But a successful demonstration is not the same as a commercial plant, factory or other asset operating at scale. Building a first-of-a-kind facility may require tens or hundreds of millions of dollars before the company can point to a long record of reliable operations and cash flow.
That creates a financing mismatch. Venture investors may be reluctant to shoulder infrastructure-scale construction and performance risks; conventional project finance, meanwhile, generally depends on evidence of dependable cash flows. The result can be a funding gap between promising technology and the first large deployment.
TechCrunch’s 2025 launch coverage described the rounds All Aboard aimed to help companies access as $100 million to $200 million for first-of-a-kind projects. That was a description of the financing need, not a commitment that the fund would supply those amounts by itself.

How much did All Aboard raise?
The $300 million figure was the fund’s announced fundraising target in 2025, not the amount it ultimately collected. ESG Today reported that the inaugural fund reached a final close at $133 million on August 18, 2026. The same report said the coalition had grown from 14 members at launch to 20 by then.
Those figures refer to different things: the target was a fundraising goal, while $133 million was the reported final fund size. TechCrunch also reported that coalition members collectively managed $60 billion in assets at launch; that aggregate figure is not capital held by the All Aboard fund. Axios reported a $50 million pledge by John Arnold at a September 2025 convening, but that reported pledge should not be read as a verified final contribution to the fund.
How the co-investment model is reported to work
All Aboard is intended to coordinate investment by climate-focused investors that have already chosen to back the same company. In its August 2026 account of the fund’s close, ESG Today described a co-investment vehicle that invests when at least three qualifying coalition co-investors independently decide to commit meaningful capital to a financing round.
The model is designed to help assemble a larger syndicate while leaving each investor responsible for its own investment judgment. Axios’s October 2025 report described the fund as matching the aggregate investments of at least three coalition members, including at least two new to the investment. The later account describes the mechanism at the time of the close; the complete legal terms are not established in the available reporting.

In practical terms, the reported model invests in companies through a financing round; it is not described as a lender underwriting a particular power plant or factory.
What the fund had invested in by August 2026
ESG Today reported three investments by the time of the fund’s final close:
- Antora: an energy storage company.
- Zanskar: an AI-native geothermal company.
- TerraCO2: a developer of low-carbon cement and concrete.
The reported portfolio shows the fund’s activity across several climate-technology areas, but the count is a snapshot as of August 2026—not a forecast of future investments or evidence of performance.
How All Aboard differs from other ways to finance deployment
Equity syndication is one possible response to the financing gap, not the only one. A useful distinction is whether capital goes into a company or a project, what evidence it requires, and who takes on construction and performance risk.
| Approach | Capital and recipient | Stage or evidence addressed |
|---|---|---|
| All Aboard, as reported | Equity or convertible equity invested in a company through a coordinated financing round; not a project loan. | Intended to help climate companies bridge from early financing toward first commercial-scale deployment; co-investors independently choose to participate. |
| Conventional project finance | Financing for a specific project or asset; the cited Autodesk Foundation account says it generally requires proven cash flows. | Better suited to projects with operating and cash-flow evidence than to an unproven first commercial facility. |
| Trellis Climate’s catalytic approach | Autodesk Foundation describes development capital, construction capital and insurance or other risk-transfer solutions. | Can address engineering and feasibility work and early construction, as well as risk management. This is Trellis’s approach, not an All Aboard offering. |
The Autodesk Foundation’s 2026 account of Trellis Climate also cited a market-context projection that 57% of U.S. climate-tech startups would need capital within 12 months. The Foundation separately reported that Trellis had raised more than $11 million in catalytic capital and mobilized more than $65 million in follow-on funding since inception. Those figures concern Trellis and the broader startup-financing context; they are not All Aboard results.

Potential advantage: larger rounds without a single lead bearing everything
A coordinated vehicle may help companies gather enough capital for expensive deployment rounds by adding a source of investment after multiple coalition members have independently decided a company merits backing. The stated rationale is to make it easier to assemble larger syndicates while preserving individual investment decisions.
Open question: does coordination improve selection?
Coordination does not by itself prove that a company is a sound investment or that a project will be built successfully. The Axios coverage surfaced concerns about groupthink, adverse selection and whether equity is the right tool for risks that may ultimately need project-level capital, debt or risk transfer. Mike Schroepfer, then head of Gigascale Capital, said collaborative investing would be approached with skepticism because investors are paid to make their own company decisions.
Chris Anderson, quoted by Axios at the September 2025 convening, argued that “the very best returns on the planet will be in these companies.” That is the fund’s investment thesis, not a demonstrated return. The reported close and three investments establish fundraising and deployment activity, but do not establish realized performance, the fund’s eventual deployment speed, complete legal terms or plans for a subsequent fund.

What founders and investors should take from the close
For founders, All Aboard is a potential source of coordinated equity capital when several participating investors already support the same financing round. It is not evidence that every company approaching its first commercial facility can access the fund, nor does the reporting establish detailed eligibility criteria or application terms.
For investors and infrastructure-finance professionals, the significance is narrower but important: a group of climate investors has created a vehicle aimed at a financing stage that conventional venture capital and project finance can leave underserved. Whether that mechanism consistently mobilizes enough capital, selects strong projects and leads to successful commercial operations remains to be seen.
