When Sat and I set up byDiffusion we had a clear goal: make consultancy more accessible.
We wanted to support the leaders who need it most — the ones in the thick of it, growing and running brilliant small and medium-sized businesses.
They don’t have endless budgets. They can’t drop five-figure retainers with big consultancies. But they do have ambition, drive, and a need for trusted support to help them scale.
SMEs make up 99.9% of UK businesses, employing millions and generating over half of private sector turnover. They truly are the lifeblood of the economy — and yet too often, they’re priced out of the help they need.
The reality is, finding the cash to invest is hard — especially when you’re juggling everything that comes with running a business.
But the leaders we work with get it.
They know that to grow, you have to invest.
And we’re here to make sure that investment delivers — not just in the long term, but from day one.
Because from day one, we said we’d build this differently.
We’re not here to fill seats.
We’re not chasing billable hours.
We’re here to build your business — and that’s how we grow ours.
Two years on, that mission still drives everything. And today, I’m boarding a flight to meet one of those clients — a brilliant team whose business is flying. We started with just a few hours a month. Now I’m meeting them on the slopes for one of their last trips of the season.
I absolutely love what we do.
And I’m proud — deeply proud — of what we’ve helped our clients achieve.
