Climate Finance Summit: Closing the Missing Middle

From San Francisco to Brazil - A Strategic Progression of Discussions to Close the Climate Finance Gap

As the urgency of climate action accelerates, capital deployment remains the biggest bottleneck to scaling climate solutions. While early-stage climate tech companies attract VC funding and large infrastructure projects secure institutional capital, the companies and projects in the middle—the ones scaling from pilot to commercial deployment—struggle to access the financing they need.

That’s why we’ve launched the Climate Finance Working Group, a series of invite-only investor and policymaker convenings designed to bridge this missing middle in climate finance. Over the next year, this working group will move from defining the challenge to structuring real financial solutions, culminating in formal investment and policy commitments at COP 30 in Brazil.

Each discussion builds on the last, turning shared knowledge into scalable action.
