In this episode of the Grand Slam Journey Podcast, host Klara Jagosova speaks with John Madura, mechanical engineer, 2x USA Rowing National Team Member, and robotics innovator at Dexterity. John's journey spans from being recruited into rowing over pizza in a college lunch line at Worcester Polytechnic Institute, to representing the United States at the World Championships in 2012 and 2015, earning a PhD at UC Berkeley, and now building physical AI and autonomous robots at the cutting edge of the industry.

From an unexpected lunch line recruitment to the USA National Team, John's path is proof that seizing unlikely opportunities — and refusing to let go of them — can lead to a life you never could have planned.

The conversation explores:

• How John discovered rowing by accident and made it to the USA National Team
• The parallels between elite rowing and long-cycle hardware engineering
• Building physical AI and autonomous robots at Dexterity
• Why hardware is the unsung hero of the AI revolution
• Teamwork, ego, and the 2016 Olympics sculling miss
• How to spot opportunities and seize them before they disappear

Want a front-row seat to how a global CFO blends tennis-honed grit with people-first leadership to rethink telecom’s future? In this episode, Klara Jagosova sits down with Jurgen Arts, Vice President & CFO for Market Area Europe & Latin America at Ericsson, who brings nearly three decades of experience leading M&A, finance transformation, and cross-regional teams.

We trace Jurgen’s path from an introverted Dutch tennis kid to a global leader known for transparency, curiosity, and balance — in business and in life. He shares how authenticity builds trust, how honesty early in a role prevents friction later, and how sports resilience fuels strategic decision-making.

We explore:
• How culture shapes leadership across regions
• M&A lessons from integrating Cradlepoint and Vonage
• The evolving role of AI as a practical co-pilot
• Building connected global teams and financial agility
• 5G network APIs and the shift to pay-per-use models
• Continuous learning, mentorship, and curiosity as long-term success drivers

🎾 Plus: Jurgen’s reflections on cooking, running, padel, golf, and inspiring his two sons to carry forward the family’s love for tennis.
