Join Dr. Jan-Philipp Mai, Co-Founder and CEO of SOLAR MATERIALS, for an unvarnished masterclass on the operational patience and physical infrastructure required to survive the clean-tech marathon. Entering the solar (PV) sector in 2010 when Germany was the undisputed global powerhouse, Jan-Philipp watched first-hand as shifting market currents moved the entire manufacturing monopoly to China. Instead of leaving the field, he deepened his focus - evolving his execution across the entire lifecycle from primary silicon synthesis to dedicated raw material recovery. In this episode, we unpack how Jan-Philipp co-founded and controls three distinct corporate pillars (Better Sol, SOLAR MATERIALS, and Circular Silicon) to secure the European solar value chain, and why scaling deep-tech hardware across Europe demands an entirely different playbook than Silicon Valley software. Insights You’ll Learn: The Cleantech Macro Timeline: Why green-tech infrastructure operates on a multi-year "marathon with several sprints" rather than the instantaneous scaling timelines of traditional SaaS.
