In this episode, I speak with Siobhán MacDermott, a cybersecurity and public policy expert whose career spans Silicon Valley, global finance, and advisory.
Siobhán reflects on an itinerant childhood and how constantly being the “new kid” shaped her relationship with risk, identity, and belonging. What began as an ambition to become an ER doctor took unexpected turns, from scouting mobile tower locations to eventually working at the intersection of cyber risk, geopolitics, and financial stability.
We talk about how she found her voice in high-stakes, often male-dominated environments, and the role risk-taking has played throughout her life.
Siobhán also reflects on her current focus protecting children from the risks of social media, connecting her work today to her own experiences of vulnerability, parenting, and growth.

In this episode, I sit down with Jay Truesdale, a geopolitical risk adviser and former U.S. diplomat and Navy Reserve officer whose career spans diplomacy, military service, and private sector leadership.
Jay traces his sense of duty back to childhood, inspired by family stories of wartime service. That early call led him into diplomacy and the Navy Reserve, with formative experiences across Russia, Ukraine, and South Asia.
We talk about the craft of diplomacy in the real world: building trust with local leaders, listening far from Washington, and learning how countries actually work beneath the surface.
Jay also reflects on his transition to the private sector, first helping bring political risk into the traditional business risk approach, and later leading two geopolitical risk consultancies. Drawing on frontline experience, he shares the frameworks he uses to help leaders think clearly about risk in a world where the old rules are rapidly breaking down.
The book Jay mentions is The Captive Mind by Czesław Miłosz, published in 1953.

In this episode, I sit down with Andres Boaz Munoz Mosquera, a former Spanish military officer, NATO legal adviser, professor of international law, and spiritual caregiver, whose life has been shaped by war, democracy, and service.
Andrés describes himself as “the product of three wars”: the Spanish Civil War, Spain’s colonial conflicts in North Africa, and the war in Bosnia in the 1990s. His family history carries the trauma of exile under Francisco Franco, a grandfather imprisoned in concentration camps, a father who returned to Spain through the Foreign Legion, and a childhood where politics were largely left unspoken.
We talk about his decision to join the military and what it meant to be trained not just as a soldier but in constitutional law. From there, he takes us to Bosnia in 1994, where serving under the United Nations exposed him to both the limits of peacekeeping and the realities of bureaucracy in wartime. Later, working within NATO, he saw how institutions function under pressure, and why he still believes international cooperation is necessary.
In the final part of the conversation, we shift to a different kind of service, Andres's call to accompany people at the end of life.
The book Andres mentions is ”Seeking in the Company of Others – The Wisdom of Group Spiritual Direction”, written by Roslyn G. Weiner (https://www.bu.edu/sth/seeking-in-the-company-of-others-the-wisdom-of-group-spiritual-direction-by-dr-roslyn-g-weiner-sth0103/).

In this episode, I sit down with Iman Kamel, an Egyptian filmmaker, writer, artist and creator, whose work explores inner resistance, transformation, and living between worlds.
Living between Germany and Egypt, Ima’s path spans dance, visual art, film, and international relations. Her films blur the line between documentary and fiction, using embodied storytelling to explore fear, rebellion, and belonging.
We talk at length about her book, Quantum Leaps & Lost Socks, where she brings together personal narrative, ancient wisdom, and “quantum” metaphors to explore transformation, interconnectedness, and what she calls the “holographic being.” The book reflects the same concerns that run through her films: how inner life shapes reality, and how meaning emerges through everyday experience.

In this episode, I speak with Guillermo de los Santos, a humanitarian fundraiser whose career began as an unintended detour.
After studying international relations with hopes of working in diplomacy, Guillermo found himself stuck in telemarketing. What felt like a dead end became an unexpected training ground in persuasion, listening, and human motivation.
A chance opportunity led him to UNICEF, where fundraising clicked as a way to combine purpose, creativity, and data. From there, he built a career across organisations such as Médecins Sans Frontières and UNHCR, developing an approach to fundraising that is both effective and ethical.
We talk about how people decide to give, the tension between persuasion and manipulation, and why asking for money in humanitarian work is often misunderstood.
This is a conversation about detours, curiosity, and finding purpose in work you never planned to do.
