We built a business before we advised yours.
The business market changed. The economy changed. We thought the accountant should too.
We started Convex from scratch — the hiring, the firing, the scaling, the quiet months where the numbers didn't add up. We've made the hard calls and lived the consequences. That's the lens we bring to your business: not theory, but the same road you're on.
Most firms start with the tax return and work backwards. We start with the conversations that move the needle — cashflow, structure, growth — and let the compliance fall out of that. It's a different order of operations, and it's the reason our clients measure us on outcomes, not hours.
We look after your money as if it were our own — because for years, building this, it effectively was.
Pragmatic, not theoretical
Advice you can act on Monday morning — not a textbook answer that needs a translator.
The long game
We’re interested in your long-term wealth, not a short-term bump in the fee.
Always accessible
A small client base on purpose. You get the partners, not a queue.
Who you'll actually deal with.

The wider team
Small and senior by design — so you work with people who know your business by name and stay on it year to year. No call centre, no revolving door of juniors.
