Jamie Siminoff had bet everything; his savings, his family's security, and his reputation, on reinventing a device from the 1800s. At the time, he had no salary, almost no cash, and a company on the edge of bankruptcy. He had been rejected on Shark Tank with only days of runway left, not to mention a court-enforced restraining order from ADT effectively halting sales. He had $187,000 in the bank to barely cover operating expenses and needed just short of $1Million dollars to secure a four-letter domain name that could carry the brand. He was certain he was making one of the biggest mistakes in entrepreneurial history. And yet, Ring survived, and what followed became one of the most unfiltered, hard-earned comeback stories in modern entrepreneurship, ending with an acquisition by Amazon for over $1 billion with more than 100 million cameras deployed in homes worldwide.

On this episode of The Reboot Chronicles Podcast, we sit down with Jamie Siminoff, inventor, and founder of Ring, to unpack one of the most unfiltered founder stories in modern tech. From the sleepless nights and bold bets to the mission-driven stubbornness that turned a simple doorbell into a global security platform. Jamie shares how he survived rejection, lawsuits, and the edge of bankruptcy. Why mission consistently outweighs money as his core motivator, and how Ring is positioning itself at the center of the AI economy by transforming more than 100 million cameras into an intelligent home platform. He opens up about his new book, Ding Dong, describing it as part business memoir and part therapy session, and one of the most honest accounts of what building a consequential, mission-based company is all about.

The warning signs were there, but the fall was still dramatic. A telecom powerhouse that once traded at $50 had slipped to nearly a dollar, burdened by debt, declining revenue, and a legacy architecture that couldn’t keep pace with the data-driven world emerging around it. Internally, the mission narrowed to survival — renew contracts, slow the erosion, hold the line. But survival mode doesn’t win in an AI-accelerated market.

So Lumen hit reset. It shed non-core assets, restructured its balance sheet, and made the hard pivot from preserving the old to building for what’s next.

On this episode of The Reboot Chronicles, Kate Johnson, CEO of Lumen Technologies, joins us to break down how she’s leading one of the boldest reinventions in modern infrastructure. We explore the cultural reboot she prioritized on day one, the shift from telecom to platform, and how Lumen is rebuilding itself to power the AI economy for the long haul.

Most global technology companies start as tight-knit engineering teams, but only a few manage to scale into organizations of tens of thousands without facing moments that fundamentally reshape how they operate. Growth at that level is about navigating inflection points that test a company’s identity, resilience, and ability to adapt. Rapid expansion, unexpected crises, and shifting market forces all play a role, and in today’s landscape those pressures are accelerating as AI, geopolitical uncertainty, and enterprise-wide transformation redefine how companies build technology and compete.

On this episode of The Reboot Chronicles, we speak with Balazs Fejes, CEO of EPAM Systems, to explore how the company transformed from a small Eastern European engineering shop into a $5.5 billion global leader in digital engineering and consulting. We unpack the leadership lessons that come from scaling through crises, the operational discipline required to build engineering organizations at global scale, and why companies that successfully industrialize AI—not just experiment with it—will define the next decade of enterprise transformation.
