You have built something ambitious. Let's make sure it's worth what you think it is.

Z Group works with ambitious entrepreneurs to grow the value of their business, systemise their finances and structure an exit that delivers more than the numbers suggest.

Most accountants tell you what happened. We tell you what to do next.

Most accountants look backwards.

If you’re building to scale or sell, you need someone thinking five steps ahead — not someone filing what already happened.

You need an advisor who looks at your business the way a buyer or investor would, and helps you close the gap between where you are and what your business could be worth.

Advisors who actually work together

Most founders have an accountant, a lawyer and a wealth manager who have never spoken to each other. We built something different: three aligned specialists who coordinate your strategy from day one through to exit.

Wealth Management
Castell Wealth Management

Your wealth management partner. Protecting and growing what you build, from early-stage planning through to post-exit wealth structuring.

Strategic Finance
Z Group

The strategic centre of the ecosystem. We coordinate the advisory relationship and act as the lead financial partner throughout your journey.

Corporate Law
Seven Legal

Your corporate law partner. From company structuring and shareholder agreements through to deal documentation and transaction support.

The three of us cover the complete lifecycle of an ambitious founder’s financial and legal needs. Finance, wealth and law, working from the same strategy. Most clients only realise how rare this is when they experience it.
