In this episode of the GeekWire Podcast, we’re joined by Marcus Fontoura, technical fellow at Microsoft and CTO for Azure Core. Fontoura is the author of A Platform Mindset, a new book that explores how to build scalable systems, support high-performing teams, and foster a culture of collaboration.

We talk about the evolving role of platforms in tech, the impact of AI on engineering productivity, and why creativity and autonomy are more important than ever. Fontoura draws on decades of experience at Microsoft, Google, Yahoo, and IBM to share insights on leadership, technical debt, and why great engineers should be treated more like artists than managers-in-waiting.

Platforms, AI, and the power of human creativity, with Microsoft's Marcus Fontoura

This week on the show, we're sharing the debut of Positive Charge, a new GeekWire podcast from reporter Lisa Stiffler and producer Laura Scott about the innovations that could help save the planet. 

In this episode, they dig into the high-stakes race to harness the power of the sun and make fusion energy real, visiting two Seattle-area startups chasing this dream, and asking whether limitless clean power is finally within reach.

Also out this week: their debut episode on the "forever chemicals" in our water and the companies figuring out how to destroy them. Follow Positive Charge wherever you get your podcasts, or at geekwire.com/positivecharge.

Positive Charge is presented with support from Amazon Sustainability.

Fusion energy: Wishing upon a star in a jar — Introducing 'Positive Charge' from GeekWire

This week: F5 turns 30 years old this year, and the Seattle company has reinvented itself repeatedly to get here — starting, improbably, as a group of University of Washington students trying to build online video games.



On this week's GeekWire Podcast, recorded on location at F5 Tower, the company's chairman, president and CEO François Locoh-Donou joins us to trace that journey, from a 1990s internet load-balancing startup to a company that helps keep many of the world's biggest apps running and secure.



Today F5 is a publicly traded company with about 6,500 employees and more than $3 billion in annual revenue, and it counts over 80% of the Fortune 500 among its customers.



Locoh-Donou discusses F5's expansion into AI security, including its acquisition of SurePath AI this week, and the company's broader M&A strategy. On a personal note, he reflects on his path from Togo to Seattle, his leadership philosophy, and his message to high school students from underrepresented backgrounds who visited F5 Tower before the company took them to a World Cup match.



Plus: his World Cup predictions, and a GeekWire trivia question that stumps the room.

With GeekWire co-founders John Cook and Todd Bishop. Edited by Curt Milton.
