I build companies, and I help the people who run them.
Thirty years in science and technology. Twenty-four of them building med tech products and the teams behind them. The last six as an advisor and investor in Auckland and on the Gold Coast. Right now that means COO at UV Sentry, strategic advisor to Dennisson Technologies, and coach to leaders in high-impact, high-risk situations through Captaincy, with a book in between.

I like building companies. I also like what happens to people when they're given a real job and backed to do it. That's why I do both, the commercial work and the coaching. They aren't two careers. They're the same thing.

Chapters from Captaincy: Reclaim Control of Life and Work sit here, along with other pieces as I write them. If you read something and think I've got it wrong, tell me.
- What is Captaincy?Captains lead from inside the game, not from the sidelines. That's the whole idea, and it applies to a life as much as to a team.
- Personal RulesA rule lets you decide once for something you'll face a thousand times. The quiet tool that does the most work.
- Captaincy of AIIf we don't captain AI, it will captain us. What staying at the wheel looks like when the tools are this good.
