    #52 Sarah Fleischer: On Battery Recycling, Deep Tech, Growing Up Between Cultures and Lessons from Failure

    In this episode, we talk to Sarah Fleischer, 3x founder and Co-founder & CEO of tozero, a Munich-based startup that recovers lithium and graphite directly from battery waste. Sarah is a mechanical engineer and CDTM alum who has raised over $20 million and recently launched tozero's industrial demo plant in Germany. We get into her path to tozero, which includes two earlier ventures that did not survive. At 22 she dropped out of CDTM to sell German baby milk formula to Chinese mothers, a bootstrapped e-commerce business that worked commercially but fell apart over a founder split. Her second company helped Chinese tourists purchase luxury goods across Europe and ultimately had to close. She talks about the three months it took to climb out of that hole, and the realization that both ventures had been driven by money rather than mission, which she now sees as the reason many founders fail. She also opens up about growing up as a third culture kid, half German and half Chinese, moving between Canada, Hong Kong and Shanghai as her father took computer science professorships around the world. She reflects on watching Shanghai transform in just a few years, what it means to never quite fit into a single culture, and how that shaped her resilience as a founder. We get into how the technology actually works. Her co-founder Xenia developed a method to extract over 97% of the lithium from spent batteries using organic additives instead of harsh chemicals, functioning somewhat like a coffee filter for critical raw materials. Sarah breaks down why lithium and graphite have remained the unsolved challenge in battery recycling, why almost 99% of refined lithium currently comes from a single country, and what the looming supply deficit from 2030 onwards means for European industry. On the business side she is refreshingly grounded. She makes the case for why owning and operating your own plants beats licensing, and explains how tozero built an industrial demo plant with just 17 million in total funding. She also talks about why Honda, Intel and Japan's JGC ended up on the cap table, and what strategic investors unlock that pure financial VCs cannot. We wrap up with a rapid fire round covering everything from deep sea versus deep space to leather jackets and late nights.

    #50 Magnus Grünewald: On AI Sovereignty, Deep Tech Infrastructure and Building High-Performance Teams

    In this episode, we sit down with Magnus Grünewald, the 23-year-old founder and CEO of Lyceum, who recently raised a massive €10.3M pre-seed round to challenge US hyperscalers. Rather than just a story about a young founder raising capital, this conversation offers a revealing look into what it takes to build "impossible" deep tech from Europe. Magnus shares how his tenure as Chief of Staff at Enpal served as a crucial lesson in losing the fear of "heavy assets." He candidly admits that starting out required a healthy dose of "delusion" to dare compete with established Tech Giants. He argues that while software is often about rapid iteration, building industrial infrastructure demands a fundamental mindset shift from tweaking buttons to moving mountains. We explore Lyceum’s core thesis of transitioning from "renting computers" to "consuming compute." Magnus breaks down his "power socket" philosophy, where AI engineers manage server uptime no more than a smartphone user manages the electrical grid. He also outlines why digital sovereignty is far more than a regulatory checkbox, becoming a critical competitive necessity for industries like BioTech. Finally, Magnus opens up about his leadership style of "extreme delegation" and how he unites PhDs and industry veterans behind a shared mission by hiring for a unique blend of "high urgency" and "conscientiousness." He concludes with a sharp perspective on the AI market, arguing that we should ignore the funding bubble and focus entirely on enterprise adoption.

    #49 André Petry: On Agency, Ambition, and Building Europe’s Industrial Future

    In this episode, André Petry, co-founder and CEO of Tacto, joins us for a wide-ranging conversation about ambition, agency, and what it means to build from Europe. We trace André’s journey from a 400-person village to CDTM, Berkeley, and eventually to founding one of Germany’s rising industrial software companies. Along the way, he shares how discovering a community of optimistic, self-directed peers at CDTM reshaped his sense of what’s possible and why that shift in mindset ultimately led him to entrepreneurship. André reflects on his early experiments building websites, online marketing projects as unlikely training grounds for developing self-reliance and problem-solving. He explains why agency, rather than pedigree, is often the defining factor in whether people actually change things, and how this belief guides Tacto’s culture today. We dive deep into Europe’s industrial backbone and why André believes the continent’s greatest opportunity lies in doubling down on manufacturing, robotics, and industrial AI. He challenges the narrative that ambitious founders must leave for the U.S., arguing instead that the strongest companies are built where domain expertise, customers, and talent are closest. He also opens up about the responsibility he feels toward the system that supported him, how ambition can be cultivated through narrative, and why optimism must shape Europe’s strategy.
