Meet The Owner

Thursday, 23 April 2026 - 59 minutes

A fascinating, down-to-earth conversation with Martin Castleton, Managing Director of Aureum Insurance Brokers, as he joins Steven Dryden-Hall on Meet the Owner. From growing up in Milton Keynes and working on the market as a teenager, to building a successful career in insurance and eventually launching his own brokerage, Martin shares the real story behind the business.

Hear how a chance opportunity led him into the industry, the lessons learned from leadership at a young age, and why stepping out to run his own company was both a risk and a turning point. Martin also explains what insurance brokers actually do, why personal service still matters, and how he’s building a business with long-term vision and national growth in mind.

There’s plenty of humour, nostalgia, and honest insight along the way — including stories from school days, early jobs, and the realities of running a business today. Plus, practical advice for anyone thinking about starting their own venture.

If you’re interested in entrepreneurship, business growth, or just enjoy hearing how real businesses are built from the ground up, this episode delivers.
