In this Deep Dive series on Climate Philanthropy, I’m exploring the wide range of ways that foundations are stepping up to support climate progress, especially amid federal rollbacks and inconsistent commitments from large companies. Philanthropic capital is tiny in comparison to government and corporate budgets, but it can still be a helpful tool – especially if wielded strategically.

Let's set some context: In the United States, there are over 30,000 environmental nonprofits. It's a wildly diverse field with organizations of all sizes and countless focus areas. Since the 1970s, they’ve saved millions of lives through environmental protections that have cleaned our air, water, land, buildings, factories, and products.

Many are struggling with funding cuts and staff shortages, and too often they compete for attention and resources.

Foundations provide funding to these organizations, but they can also play a more fundamental role: building movement infrastructure that bolsters the power and influence of the entire field.

That, argues Pisces Foundation President David Beckman, is a priority that deserves more attention and support. David is a friend whom I’ve had the pleasure of working with over the years. When it comes to investing in movement infrastructure, I can’t think of anyone else who brings the nuance and insight David has gained through a career-long focus on advancing the environmental movement. We talk about his background as an National Resources Defense Council attorney, his role in helping start the Pisces Foundation, the entreprenuerial nature of his work, what movement infrastructure is, what he’s learned about investing in it, the importance of late night cookies in building relationships, the need for a meta narrative, the work of the Pisces Foundation, super pollutants, what business people and young people should know about the environmental movement, and much more.

In the second installment of our Deep Dive: Missing Middle in Climate Tech series, created in partnership with Spring Lane Capital, we dive deeper into why the “missing middle” is not just a gap; it's a structural issue. We're joined by two of the sharpest minds in climate investing: Francis O’Sullivan, Managing Director at S2G Investments, and Rob Day, Co-Founder of Spring Lane Capital. Together, they explore how early-stage innovation and late-stage deployment are well funded, while the crucial middle phase of scaling is dangerously underserved.

We discuss why this gap exists, what solutions are emerging, and how investors are shifting their strategies to meet the moment. If you care about accelerating the climate transition, you’re going to want to listen to this.

What You’ll Learn

• Why the "missing middle" persists despite surging climate capital overall
• How venture capital models can distort scale-up potential
• What new capital strategies (like development expense financing) are emerging
• Why climate investing now enters a “third phase” of full-scale deployment
• How Rob and Francis are rethinking returns and risk for the climate transition

In today’s episode, we cover:

• [2:50] Francis' background and journey to S2G
• [4:36] Rob's career path in climate tech investing
• [6:30] Spring Lane Capital's founding and investment thesis
• [9:54] Discussion of the missing middle in climate finance
• [19:04] Structural challenges in climate investment
• [25:46] Organizational challenges for institutional investors
• [33:57] Concrete investment examples
• [41:37] Explanation of structured investment instruments
• [44:26] Historical context of climate investing

The climate transition requires not just allocating trillions of dollars to scale new technologies, build new infrastructure, and transform incumbent industries – it requires getting the right mix of capital to develop, grow, and eventually scale innovations.

In the world of climate, promising technologies too often don’t find the growth-stage capital that’s needed before large institutional investors can finance reaching scale. Addressing this missing middle is a structural challenge that requires more attention, and today’s episode is the first in a series of discussions on the missing middle in climate, developed in partnership with Spring Lane Capital.

In this conversation, I’m joined by Jason Scott, a long-time climate investor who is Partner in Residence at Spring Lane Capital and also Board Chair of CREO Syndicate, and Régine Clément, CEO at CREO Syndicate. Spring Lane has been investing for years in the missing middle and has unique expertise in the challenges and opportunities it holds. If you haven’t heard of CREO, this is a group you should know. CREO works to help family offices invest more in climate. Families hold over $10 trillion in assets and can bring versatility and resilience that can help improve climate finance. CREO is working to mobilize $1 trillion for climate in the coming years. We talk about insights from their recent report on the missing middle, how climate investing has evolved in recent years, the role of catalytic capital, whether investors are backing away from climate amidst changing policy and macro-factors, and much more.

This was a great kick-off for our Deep Dive: Missing Middle in Climate Tech series, and I hope it piques your interest in the other episodes as well. And, if it piques your interest about partnering on a topical series of your own, don’t hesitate to reach out.

The voluntary carbon markets have been a source of curiosity for me. There’s been a lot of hope that the market would mature and offer a reliable way to offset emissions that otherwise could not be eliminated. Reliability has been the problem, however. Not knowing which carbon reduction projects are additive and truly remove or reduce carbon has held this market back, and I’ve been excited to learn about how new technologies will enable the reliability that’s needed.

There are many people working on this problem. Dr. Allister Furey, Founder and CEO of Sylvera is one, and I was excited to learn about his company’s approach to removing carbon market bottlenecks and accelerating the investment in carbon projects. As he says it’s a mix of software, data, AI, and analysis that have helped Sylvera work with large clients and unlock enormous investments. Hope you learn as much as I did. Enjoy.

Non-dilutive funding isn’t just about landing the grant; it’s about delivering on it with excellence. In the third episode of our Deep Dive Series with Climate Finance Solutions, we go beyond the application and explore what happens after the award. Our guest host Joel Armin-Hoiland, Founder & CEO of Climate Finance Solutions, is joined by two experts who live and breathe this work: Susan Perri, Director of Grants at Climate Finance Solutions, and Jeff Haydock, CEO of ecoCFO.

Together, they unpack the essential strategies behind post-award grant management from navigating audits to implementing smart financial systems, crafting efficient technical reports, and making strategic choices long before the application is even submitted. The episode offers real-world insights into federal grant reporting, shifting expectations with the new administration, and how startups can build internal or external capacity to manage complexity without losing focus.

It’s not yet clear exactly how devasting the loss of federal funding for climate nonprofits and climate tech companies will be, but we know the toll will be high. Beyond the funding freeze, there have also been rumors of other federal action targeting nonprofits in this space.

No one knows exactly what will happen, but it’s clear that philanthropy is more important than ever. Philanthropy alone can’t fill the gap left by the government, but it can make a real difference.

This episode is the first in a series of conversations we’ll have this year focused on climate philanthropy.

We’re starting with not only one of the biggest climate foundations in the U.S., but also one that combines philanthropy with investments designed to catalyze more capital flows to climate. The MacArthur Foundation has long been a leader in using this impact investing approach to improve the ROI for investors seeking market-rate returns.

In today’s conversation, we’re joined by MacArthur Foundation’s Director of Impact Investments John Balbach and Program Officer Deborah Philbrick. We spoke about the Foundation's holistic, problem-first approach to climate, what that means for both their philanthropic funding and impact investing, how they’re stepping up to what they see as a civil society crisis, and much more.

Lots to learn and think about in this one. Let me know if you have ideas about other foundations to feature in this series. Here we go.
