   #26 - Alfonso “Poncho” Martínez - The Subtle Art of Networking

   From working and studying simultaneously from the age of 17, to helping build IKEA Mexico as employee number 51, and now graduating as the class speaker of the IMD MBA Class of 2025, this is the story of Alfonso “Poncho” Martínez (https://www.linkedin.com/in/alfonsomtz/). In this episode, we sit down with Poncho to explore what it means to build a life anchored in relationships, humility, and courage. We talk about learning to “care and dare,” why networking only works when it’s not transactional, how becoming a father shifted his identity forever, and how to stay true to your strengths while still confronting your past with honesty. Key Takeaways & Highlights 1. Connection Is Energy. Poncho is fuelled by people. He doesn’t network to extract opportunity; he connects because it gives him energy and expands his world. His earliest influences, parents and grandparents, shaped an instinct to approach others with curiosity, generosity, and joy. 2. Add Value First. His career breakthroughs all began with offering something of value with no expectation in return: a cycling buddy for a country manager, an invitation to lunch for an executive who always wanted to visit IMD, a book recommendation, an introduction, a kindness. “You plant the seed and you never know when it grows.” 3. Secure-Base Leadership: 100% Care, 100% Dare. Poncho discovered that while he excelled at caring, he often fell short on daring: pushing people, holding boundaries, or asking for tough feedback. Learning that both are required to unlock potential (in others and himself) was a transformative insight of the MBA year. 4. Parenting as the Ultimate Leadership Role. From device-free “family board meetings” to the radical importance of presence, Poncho sees parenthood as a daily mirror: your child absorbs everything you do. And the biggest lesson? “Once you are a father, you will always be a father.” 5. Scars Don’t Have to Close You Off. A failed business partnership hurt him deeply, but instead of turning cynical, he reflected on what he could have done better: diligence, boundaries, structure. The insight: you can still trust people, but with different levels of trust for different contexts. Not everyone is meant for business, but they can still be a friend. 6. Humility, Stability, and the Simple Life. His grandfather, who lived to 102, modelled a life of high aspirations, moderate expectations, and low needs. A few white shirts, a few shoes, strong values. It shaped Poncho’s definition of success: fulfilment over accumulation. What We Learned John: The secret to networking (and to life) is generosity. Poncho never approaches people to get. He approaches to give, and somehow, opportunity finds him anyway. He is proof that nice guys do finish first. Konsti: That connection doesn’t have to be binary. You don’t need to limit who you engage with; every person can be a future story, a future lesson, a future friend. And Poncho shows what it looks like to approach people without fear of “too many relationships.” Poncho: To trust himself more. To keep being who he is. And to continue caring and daring, with friends, classmates, colleagues, and his family. “The life is now.” This is a public episode.

   #25 – Katharina Lange – Chase Excellence, Not Perfection

   From completing a PhD in pharmacology and toxicology to consulting across industries and ultimately teaching leaders on three continents, this is the story of Katharina Lange (https://www.linkedin.com/in/leadershipimdkatharinalange/), IMD Professor of Leadership, whose work blends strategy, psychology, and character. In this episode, we sit down with Katharina to explore what true leadership demands of us: courage, humility, self-awareness, and the discipline to make choices that honour the person we want to become. We discuss why vulnerability only works when grounded in competence (with a dash of humour), why hard work has no substitutes, and why “a good life” is really about creating stories worth telling when you’re 80. Key Takeaways & Highlights 1. Leadership Begins With Self-Honesty. “You can pull the wool over somebody’s eyes for a while. Don’t pull it over your own.” Ask for honest feedback. Invite people who love you enough to tell you the truth. And don’t wait until it’s too late to look in the mirror. 2. Excellence Over Perfection. Perfection doesn’t exist, not in leadership, not in organisations, not even in ourselves. But excellence sets a dynamic direction: trying to be better tomorrow than you were yesterday. 3. Hard Work Always Pays Off… Eventually We live in a culture of instant gratification, yet leadership is slow-cooked. “Hard work always pays off — sooner or later. Usually later,” she laughs. There are no shortcuts, and if you think you’ve found one, you probably haven’t. But the work is worth it, because mastery builds conviction, and conviction builds character. 4. Parenting Is the Hardest Leadership Laboratory Boundaries. Standards. Humility. Consistency. Many of the lessons Katharina teaches in the classroom began at home.And one of her strongest convictions is this: “parents shouldn’t try to be friends with their children.” 5. Careers Are Not Ladders — They’re Portfolios. Katharina challenges the upward-only obsession of “career.” Real careers are collections of experiences: some paid, some unpaid, all meaningful if you extract the learning. Eventually, leadership roles find those who are ready, not those who chase. 6. Lead Your Life Future-Back. One of Katharina’s most profound ideas: Think from your 80th birthday backwards. Who is in the room? What stories do you tell? What choices did you make that allowed you to live a full life? What We Learned Konsti: That the real substance of leadership doesn’t come from frameworks or corporate templates, it comes from stories, humour, art, failure, courage, and lived experience. John: That serving others, not chasing titles, is what leads to meaningful careers. And that the challenges we face today are not unique - it has always been hard. Katharina: That I love doing this. And that I need to think more about the truths I hold that others might not share. This is a public episode.

   #24 – Kevin Martelli – On the Importance of Trust-Based Relationships in the Early Days of Ambitious Companies

   From building a successful career in investment banking in London and Italy to helping deep-tech founders turn groundbreaking science into world-changing companies, this is the story of Kevin Martelli (https://www.linkedin.com/in/kevin-martelli-956558/) - investor, advisor, and founder behind Delta Plus Ventures (https://dplus.ventures/). In this episode, John and Konsti sit down with Kevin to explore how character and conviction shape great ventures, why trust compounds faster than capital, and what makes a founder truly exceptional. They unpack lessons Kevin has picked up from over 500 conversations with founders, discuss how to build skills that give you optionality in your career, and how to build a life that keeps your curiosity alive. Key Takeaways and Highlights 1. Character Over Plans. Kevin never pays much attention to business plans – he focuses on people. “Staring at numbers on Excel for too long can easily fool you into believing projections. Observing the character of a founder can be more insightful when assessing the chances of success of a bold dream.” 2. Conviction and Curiosity. The best founders hold strong beliefs combined with an unusual ability to listen. “You need both conviction and humility to learn in the same person – that’s rare.” 3. Care Deeply and Outlast Indifference. The job of a founder is to care deeply about the challenge/solution they are focusing on and to outlast others' initial indifference to their view of the world. 4. Trust Compounds Faster Than Capital. Kevin’s work is built on trust-based relationships: “I might be the first to believe in you, and the last to stop believing.” 5. Build Your Tribe Early. Build Your Tribe Early. Careers are shaped by mentors, not titles. Be intentional about the people you surround yourself with and how you build your “personal board of directors”. 6. Delta Plus Philosophy. Named after Sergio Marchionne’s quote: “What matters at the end of the day is to have made a positive difference.” In your interactions with others, it is both important and challenging to add real value and find win-win situations. What We Learned Konsti: Good careers are built by following energy – talking to people who make you want to do more. John: Filtering is everything. The quality of your life = the quality of the people you choose to believe in. Kevin: Your career and character are interlinked. You are the average of the founders and friends you spend time with – so choose wisely. This is a public episode.
