Transitioning into management consulting, she worked on supply chain and procurement projects in London and Southeast Asia, where she developed a passion for climate change solutions. Her experience running venture accelerator programs in Southeast Asia for impact-driven startups inspired her to focus on early-stage climate tech investing.

Their investment strategy emphasizes three key criteria: Impact, Additionality and Commercial Potential. In July 2023, Azolla Ventures announced the final close of their fund at $239 million. This fund blends catalytic, charitable capital with impact-aligned, market-rate capital to drive investment into solutions with deep potential for climate impact that are systemically overlooked by conventional financiers. Amy has even constructed a microcosm of LP signals that they use to understand where investing gaps in the ClimateTech funding ecosystem lie. In this episode, Amy shares insights on:Using blended finance to de-risk early-stage climate tech investmentsThe unique challenges and misconceptions in hardware-focused climate startupsEmbedding equity and justice in climate tech venturesEnjoy!📝 Show Notes:Topics 05:50 The Role of Blended Finance11:51 The Unique Landscape of Hardware Companies15:04 Building Trust with Entrepreneurs17:49 The Importance of Environmental Justice21:01 The Future of Climate Tech Investing28:54 The Art of Simplifying Complex Technologies31:52 Investing Ahead of the Curve39:59 Integrating Equity and Justice44:08 Future AspirationsLinksAmy Duffuor | Azolla VenturesConnect with Somil on LinkedIn | Connect with Silas on LinkedInFollow CleanTechies on LinkedIn@Silas & @Somil_Agg on X This podcast is NOT investment advice.

The conversation tackles the challenges ClimateTech faces under the Trump administration. It highlights strategies for building politically resilient companies while navigating the shifting political landscape. Rural vs urban climate perspectives are discussed, emphasizing communication and collaboration. Innovative marketing and the importance of engaging non-climate investors receive focus. The podcast also delves into the potential opportunities in emerging technologies like hydrogen and the importance of strategic partnerships in progressive states.

Today we are joined by Duncan Logan, CEO & Co-Founder of 9Zero. A community platform to bring climate professionals together in person and online so we can work together to solve the climate crisis. Duncan previously founded RocketSpace where he saw many tech startups that would go on to become unicorns. Companies like Uber, FlexPort, and Spotify. Having this experience made him realize the importance of creating a hub for people to collaborate and bump into each other. They are extending this even further by building these hubs in all major climate cities because unlike the 2000’s tech boom, there is no one silicon valley for climate. We need to connect NY, DC, Boston, Houston, London, Berlin, SF, Seattle, and beyond. Duncan brings a lot of experience and some great stories (like the time he met Elon). Enjoy! ---🌎 Want the full Pod?
