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?

Today, we are speaking with Liz Dennett, the CEO and Founder of Endolith. Endolith recently spun out of Cemvita to form its own independent company. (Ep #200 with Moji from Cemvita)By 2050, we will need more copper than in the history of mankind due to the electrification of industry and developing countries.
