Life After the Exit: Building Again

North Stars, Endurance, and Long Games

Final Advice and Closing Thoughts

Jamie breaks down what really happened after his Shark Tank pitch, how visibility mattered more than the deal itself, and why building a fast-growing hardware company can be dangerous. He explains the brutal cash cycles behind Ring’s growth, how close the company came to running out of money, and what ultimately led to selling Ring to Amazon for over $1 billion.

Beyond business, Jamie talks about running as a daily reset, why he hires people who think like marathoners, how consistency compounds over time, and what it takes to keep making decisions when there’s no clear finish line. He also shares how mission — not products — scaled Ring, and why building things that genuinely help people has guided every phase of his career.

A wide-ranging conversation on endurance, uncertainty, and what long-term progress actually feels like while you’re still in it.

Post Run High

Post Run High is a podcast about honest conversations that happen when people slow down and let their guard drop.

Hosted by Kate Mackz, the show brings together founders, creators, athletes, artists, and thinkers to talk about performance, identity, pressure, and the moments that shape who we become. Recorded after a run, walk, or shared movement, these conversations tap into the clarity that often comes when the body is tired and the mind is open.

This isn’t a show about success on paper. It’s about what people carry behind the scenes — how they cope with doubt, navigate change, stay disciplined, and keep going when things get hard. Post Run High is a space for reflection, perspective, and real insight you can take into your own life.
