97. Marlan Macklin | From Army Brat to the Pentagon: 6G, AI & America’s Wireless Future

In this episode of the Grand Slam Journey Podcast, host Klara Jagosova speaks with Marlan Macklin, Deputy Principal Director for FutureG within the Office of the Under Secretary of War for Research and Engineering, where he guides the U.S. Department of War’s efforts to advance research, development, and investment priorities for 5G, 6G, and future-generation wireless technologies. Marlan grew up as an Army brat bouncing between military bases across the East Coast and Southeast, competed in athletics alongside two brothers who were, by his own admission, the better athletes, and chose The Citadel, one of only six senior military colleges in the U.S., at 18 years old. Before joining FutureG, he served at the U.S. Mission to NATO as Chief of the Communications and Electronics Division, negotiating international agreements across the Indo-Pacific, Europe, and the Middle East, and making it a personal mission to set foot in every single NATO allied country. The conversation explores: Why growing up on military bases builds an adaptability most people spend a lifetime chasing What The Citadel gives you that no traditional university can How negotiating international defense agreements across three regions shaped his leadership Why building trust across 32 NATO allies starts with eating their food What AI RAN means and why 6G is really an AI infrastructure story How Integrated Sensing and Communications could protect the 2028 Olympics from weaponized drones Why the U.S. is betting on open architectures and commercial partnerships to win the next technology race And why he comes home from Easter Island more tired but more alive than when he left 🔗 Connect with Marlan: linkedin.com/in/marlan-macklin 🌐 FutureG Office: rt.cto.mil/ddre-rt/science-and-technology-futures/futureg-home Send us Fan Mail This content is also available in a video version on YouTube.

96. Susan Brennan | From Plant Floor to CEO: Leadership, Resilience & Still Standing

In this episode, Klara Jagosova speaks with Susan Seilheimer Brennan, executive, operator, and author who has spent nearly four decades leading organizations through growth, transformation, and scale across automotive manufacturing, clean energy, and advanced materials. Susan's journey spans growing up in a working-class steel town in Illinois, building her career from a plant floor in rural Iowa to VP Manufacturing at Nissan where she drove the first Nissan LEAF off the production line, to COO at Bloom Energy where she tripled headcount, cut unit costs by 70%, and took the company public, to CEO at Romeo Power and 5E Advanced Materials where she led turnarounds under extraordinary pressure, and now advising early-stage clean energy and tech founders at EnerTech Capital. The conversation explores: Why she walked away from a Ford executive pension to bet on the electric vehicle. How she moved her family from Nashville to Silicon Valley at 51, going from big fish to minnow, and why she did it anyway. What the plant floor teaches about leadership that no MBA can. How the Hoshin X Matrix connects individual work to company-wide goals. How to break the constraints blocking progress when everyone is already working hard. Why she believes innovation is the heart, and without it, even the strongest organization won't survive. What made her write the whole truth rather than the Instagram version. Why she chose to bring light to things most people keep in the dark. Get the book: Still Standing: From Self-Loathing to Self-Love by S.

95. Katie Calhoun | From Forbes to Getty Images to Founder: AI, Bias & Human Connection

In this episode, Klara Jagosova speaks with Katie Calhoun , Founder and CEO of Two-Bridge Growth Insights and Managing Partner at ResonateLab , where she helps organizations use generative AI to facilitate human connections rather than replace them. Katie's journey begins not in a boardroom but behind a camera lens. With a BFA from Cornell, she started as a photo editor and writer, worked her way up at Forbes, then deliberately walked away to learn the one discipline she hadn't yet mastered, sales, at Hearst. That decision led her to nearly 18 years at Getty Images, where she led a team of 110+ people, drove over $300M in annual revenue, helped take the company public, and played a key role in launching Generative AI by Getty Images. The conversation explores: Why AI can't replace human instinct, storytelling, or genuine connection The AI bias problem: how generative models "reduce to the mean" and quietly erase diversity The Getty Images playbook: launching generative AI without losing the creative soul Building #ShowUs, Disrupt Aging, and the LeanIn Collection to challenge visual stereotypes across 170+ countries Lessons from Cannes Lions on moving from AI hype to intentional adoption Advice for women on negotiation, leadership, and using your voice Whether you're a marketer, a founder, or someone navigating your own reinvention, Katie's journey is a masterclass in following curiosity, learning your gaps, and staying rooted in human insight in an increasingly automated world.

94. Stephen Rose | From 5 Airborne to Tech CEO: Military Leadership, AI & Scaling Render Networks

In this episode, Klara Jagosova speaks with Stephen Rose, CEO of Render Networks , former Managing Partner at Nokia Bell Labs, and General Manager of Global Industries at IBM. A 25-year telecommunications and technology leader who served in the British Army 5 Airborne Brigade before building and leading businesses across four continents, Stephen brings a perspective on leadership, AI, and infrastructure that is anything but conventional. Stephen's journey spans serving in the elite British Army 5 Airborne Brigade, building a consultancy from zero to €11M and 90 consultants, leading Nokia's largest ever services deal at over $1B, reskilling 40% of IBM's global headcount, and now leading Render Networks at the most consequential moment in American broadband history. The conversation explores: What the 5 Airborne Brigade actually teaches you about leading people under pressure. Why most leaders get hierarchy completely wrong — and the distributed leadership model that works. How Stephen navigated engineering boardrooms for decades without a formal engineering degree. How radical transparency got 40% of IBM reskilled faster than any performance review ever could. Why fiber and electric infrastructure builds are now one race — and what the next 24 months look like. How AI is reshaping how field crews build and verify networks at scale. The fear bubble framework for separating real risk from perceived anxiety. 🎗️ Stephen is running the annual Para 10-miler to support veterans battling cancer and suicide.

88. Rani Yadav-Ranjan ︱ AI for Humanity's Sake

What if we could revolutionize healthcare and other industries by using the untapped computing power that sits idle in hospitals every night? Meet Rani Yadav-Ranjan , Chief AI Officer at Greycloud AI, who's pioneering a breakthrough approach to AI that respects both data privacy and urgency. After watching her mother's medical journey, Rani had a revelation: doctors function as "databases" of knowledge, but these repositories remain isolated within individual hospitals. Her solution? A patented system that transforms existing computers in closed networks into distributed training devices, operating during off-hours to build sophisticated AI models without compromising sensitive patient data. "From six o'clock till six in the morning, that's twelve hours of computing power we could use," she explains, describing how her technology chunks and chains data through multiple nodes, each with a unique blockchain identifier to ensure validity. This innovative approach reflects Rani's decades-long career at the intersection of emerging technologies. As one of the most influential women in tech, with over 20 patents, she pioneered mobile payments in the early 2000s, navigated cultural resistance to e-commerce in Japan, and continues to advocate for the ethical development of AI. Through personal anecdotes about balancing leadership with motherhood and observations about gender bias in corporate cultures, Rani offers a master class in resilience and strategic thinking. Rani's perspective on AI's future is refreshingly nuanced. Rather than fearing job displacement, she sees AI as enhancing human capabilities while emphasizing the irreplaceable value of experience. "What I use AI for is code reviews," she notes. "It's awesome to say, 'here's 3,000 lines of code, tell me where the missing semicolon is." As she prepares to publish her book "Constitutional Democracy in the Algorithmic Age," Rani continues to champion responsible innovation that serves humanity's needs while respecting our rights and privacy. Connect with Rani on LinkedIn to follow her groundbreaking work at the intersection of AI, healthcare, and ethical technology development. https://www.linkedin.com/in/ryadavranjan/ https://yadav-ranjan.com/ Send us Fan Mail LEORÊVER COMPRESSION AND ACTIVEWEAR Get 10% off Loerêver Balanced Compression and Activewear to elevate your confidence and performance 8 EIGHT SLEEP Save $200 on 8Sleep and get better quality and deeper sleep with automatic temperature adjustment Disclaimer: This post contains affiliate links.
