#152: Serial Founder Tackles $80B Renewable Energy Tax Equity Finance Market — Andy Moon, CEO of Reunion
⭐ My guest today is Andy Moon, CEO and Cofounder of Reunion.
Reunion's mission is to accelerate investment into clean energy. The Inflation Reduction Act created a simpler way to finance solar, wind, battery storage, and other clean energy projects through the sale of tax credits. In July 2023, Reunion launched a marketplace for corporations to identify, due diligence, and purchase tax credits from leading project developers. Reunion raised corporate funding from leading clean energy investors in January 2023, and their founding team previously raised over $2B to finance solar energy projects around the world.
Andy is the former CEO of SunFarmer, a Y Combinator-backed social enterprise that has completed over 1,500 solar energy installations in Asia. Previously, he raised over $200 million from institutional investors to finance solar energy projects in the US and Europe, and worked as a consultant in the energy and buildings practice at McKinsey and Company. He was also an early advisor to Possible Health, a leading public health nonprofit. Andy holds a Phi Beta Kappa honors degree from Stanford University and was named a 2016 Young Global Leader by the World Economic Forum.
---
🎙️ In this episode, we talked about:
Our shared experience of the friction required to use tax equity to finance solar projects going back to 2009-2010. How those high transaction costs and bottlenecks are still a part of this financing mechanism today. The drastic increase expected in tax equity funding from around $20B today to over $80B in a few years.
The process he used to pick this new venture. Why his cofounder selection was so important. What he learned from building SunFarmer, a Y Combinator-backed startup funding distributed solar installations in Asia. His 90/10 rule on focus.
What his managed marketplace at Reunion makes tax credit transferability easier between project developers and corporate buyers. How tax credits can fund 30-50% of a project. The costs to buy these credits.
The role of newer technologies in the tax credit landscape, such as hydrogen and biogas. Why his team uses the two-week sprint model to manage performance. How the book Radical Candor has shaped Reunion’s culture.
And lots more!

#151: Here's How You Purchase Carbon Removals with Philanthropic Capital — Adam Fraser, CEO of Terraset
⭐ My guests today are my collaborators at Terraset, the anti-GHG 501c3 that purchases CDR (aka, carbon removals) using philanthropic dollars.
Adam Fraser is our new CEO. Alex Roetter is the founder and also GP at Moxxie Ventures. Erzsi Sousa is also a Board member and wizard brand strategist.
I guess I’m a host and guest, too, as a cofounder and Board member of Terraset, too.
---
🎙️ In this episode, we talked about:
Why Adam took the leap and joined Terraset, leaving behind a CEO role at a multinational impact NGO. Why we chose Adam, instead of a CDR expert, to scale up Terraset.
The types of donors supporting Terraset’s mission and why they’re contributing (i.e., to build an entirely new and crucial industry, not to get offsets)
How we prioritize which CDRs we purchase. The recent growth in CDR purchases year-over-year. Our thoughts on engineered vs. nature-based solutions. And lots more…
Hope you enjoy it!

Previously, Steven ran the world-renowned Perkins School for the Blind, as well as Environmental Futures, Citizen Schools, and the John F. Kennedy Library Foundation.
---
🎙️ In this episode, we talked about:
The lack of substance behind state-level anti-ESG investing headlines. The overwhelming majority of people who believe businesses can achieve a public good and generate market-rate financial returns. The Ceres Freedom to Invest program to make this a red, white, and blue issue, and not just a green issue
How the TCFD frames risk and opportunity creation for investors in a low-carbon future. Why 92% of the Fortune 500 companies conduct sustainability reporting to investors. The SEC and California state greenhouse gas disclosure rulemaking and what it means for 8,000+ companies.
What the insurance industry’s $40B of losses last year could mean for the future of that industry in a world where major weather events occur every two weeks today vs. every four months in 1980.
Why this quote from H.L. Mencken is relevant: "For every complex problem, there's a solution that is simple, neat, and wrong." How the banking industry might face more risk from climate exposure today than the risks it faced in the subprime crisis of years past.
And lots more!

⭐ My guest today is Laura Zapata, Cofounder and CEO of Clearloop.
Clearloop creates carbon solutions for organizations of all sizes, from global corporations to small businesses and educational institutions, to decarbonize the economy, expand access to clean energy, and accelerate the development of new solar projects in American communities where the greatest economic and environmental benefits can be achieved.
Clearloops works in partnership with utility-scale solar developer Silicon Ranch, which acquired Clearloop in 2021.
In addition, Laura is the former Head of Global Communications for Uber Eats, Press Secretary for Hillary Clinton’s Presidential race in Ohio, and communications lead for other Congressional offices.
---
🎙️ In this episode, we talked about:
How to get Taylor Swift to partner with Clearloop (half serious). What she learned by working at Uber in a “move fast and break things” mentality. Having the former Governor of Tennessee as a cofounder (a first for our podcast). How to move from being an intrapreneur with Uber Eats to an entrepreneur. The importance of being optimistic.
What we all need to do to improve climate tech’s communication strategy to broaden the tent (btw, pop quiz: how many degrees Fahrenheit is 1.5 degrees Celsius?). Why working with renewables in the South can have more impact given the carbon intensity of the power grid. How Clearloop’s model of carbon offsets for corporates changes how renewable energy power plants are financed. The need to build a life, not just a career (and the joy of farmer’s markets).
And lots more!

#148: $100M from Insurance Giant for U.S. Climate Tech Startups — Tim Krysiek, Managing Partner at MassMutual Ventures
⭐ My guest today is Tim Krysiek, Managing Partner at MassMutual Ventures.
MassMutual is an insurance and financial services firm with $460B in AUM, and MassMutual Ventures is their venture arm.
Their new US Climate Tech Fund represents $100M and is focused on early-stage opportunities (Series A and B) in climate intelligence, sustainable cities, and clean power. Initial check sizes are $2-5M.
Tim was previously Managing Director at Equinor Ventures where he worked across the energy value chain, including renewables, fusion, mobility, and storage. He was also a consultant at Cambridge Energy Research Associates (now S&P Global), a researcher at the Oxford Institute for Energy Studies, and a political risk consultant at Google.
Krysiek achieved all these great things because he got an MBA from Duke University, where I teach. (OK, I exaggerate slightly.)
When not investing in world-changing companies, I hear that he’s an aspiring Eastern European cook focused on the 3Ps – pierogies, pelmeni, or potica.
---
🎙️ In this episode, we talked about:
His team’s work investing in five climate tech unicorns
How his study of geopolitics across twelve countries shaped him into an investor
What their climate intelligence focus means in terms of cheaper data and falling processing costs
How the Net Zero Tracker of corporate climate goals influences their thesis around voluntary carbon markets
Why he’s excited about investing in proptech given the durability of buildings and the potential value that MassMutual can create for companies in that space
What he means by keeping one foot on certain ground and the other on uncertain ground
How much water he drinks per day and its relationship to the number of steps he takes per day
His three favorite climate books and three favorite business books (Power Law, anyone?)
And lots more
