There are people who think about culture. And then there's Didier Elzinga.

Fifteen years running CultureAmp. 7,000 organisations. A front-row seat to how culture forms and fractures - the writedowns, the departures, the hard conversations that don't make it into announcements. During this episode, Didier draws on Buddhist philosophy, Buckminster Fuller, spiral dynamics, Brené Brown and more. Not as decorations but as working tools for a CEO who has spent two decades in the room when things go wrong and when they go right. He knows the difference between organisations that are succeeding and ones that are performing success.

That's the vantage point he brings to AI. Not the model specs or the market positioning. The human question: what happens to culture, identity, and the way we work together when the tools change this fast? Who holds the values of an organisation when part of its team isn't human? And does context - the real context, the stuff that lives in a company's bones - survive the remaking?

He also has a question he's been considering that has nothing to do with AI. The one every founder eventually faces, usually alone. When your identity and your company have been the same thing for twenty years - who are you when that changes?

Kate sits down with Didier to go there. On culture, on AI, on what a leader owes the people who follow them. And on what, exactly, is worth protecting.

If you're here for commentary on the Pope, Trump, or the geopolitics of frontier AI - this isn't that episode. If you're here for the unfiltered view from the people actually building Claude - stay.

This one is for the builders, the tinkerers, and the curious. Two of the people behind Claude - not here for governments, the press, or the Vatican. Instead, here to zero in on what they're seeing, and how you can get more from AI, however you're using it.

Katelyn Lesse runs engineering for Anthropic's Claude Developer Platform. Angela Jiang runs product. They're the people closest to what builders are actually doing with the technology and are exactly the kind of spark people they'll tell you every team needs.

What they're seeing: teams that transform overnight because one person in them is genuinely obsessed. Founders who move with the model instead of against it. A shift from "content is king" to "context is king" that most people haven't caught up to yet. And a clean slate advantage - available to anyone willing to look at an old problem as if it's never been solved before.

Earlier this year, Eucalyptus sold for $1.6 billion - one of the biggest exits in Australian startup history. Charlie Gearside co-founded it.

A year on, he's spending his time on YouTube and on Build Australia, the nonpartisan movement he launched last month to make space for a more ambitious version of this country. He talks publicly about property investing, the universities, and a culture that calls earnest people try-hards. None of it is comfortable, and none of it is what most people do after an exit.

He's also the first to admit that none of this pays off quickly. The work is to shift what Australians think is acceptable to want. A project that’s measured in decades, not quarters.

Kate sits down with Charlie to talk about untangling your identity from a company you built. The brutal question he had to ask himself before leaving Eucalyptus. Why he won't go into politics. Why he thinks the most risky thing right now might be doing nothing. And the one topic he's still too nervous to make a video about.
