About Jason Campbell

About

Eighteen years coaching. Nearly four decades in business.

I’m an Executive, Leadership and Team Coach, and before that I spent my working life running companies of my own. That order matters — almost everything I know about business, I learned by getting it wrong first.

Clients get a coach who has sat in their chair.

How I got here

I started my first business in my bedroom at 19 and sold it at 23. I went on to build two more — one from two people to 38, the other from 15 to 400 with offices worldwide.

I’ve been coaching for 18 years, and had already been doing it for several years before I sold my last business. So the coaching didn’t start when the running stopped. They overlapped.

What I actually do

Three things, and they’re more connected than they look: coaching senior executives and leadership teams, helping SME owners reset and grow, and fixing cultures that have drifted.

Don’t let one put you off the other. I work with some large global brands. If that makes you think you’d be too small, or that I’d be too expensive, neither is true.

How I work

Directly. I’m not going to sit there nodding and reflecting your own words back at you — you can do that on your own for free.

If I think you’re wrong I’ll say so, and if I’m not the right person to help I’ll tell you that too.

Where I work

The UK, Europe, the UAE and Japan. I’m based between London and Hertford, and a lot of the UK work happens in person.

I’m also BIMA’s resident coach for the UK digital industry, and I assess developing coaches through London’s Business Coaching Academy.

A bit about me

My work is purposefully varied

I’m passionate about senior executives performing at their best, and about what honest communication does to a culture. I’m just as passionate about small and medium business owners — I’ve been one for most of my life, building from scratch and taking over companies that were struggling.

Don’t let one put you off the other. Yes, I work with some large global brands — you can see them below. If that makes you think you’d be too small, or that I’d be too expensive, neither is true.

I started my first business in my bedroom at 19 and sold it at 23. I’ve been coaching for 18 years, full-time since 2015. My own companies have gone from 2 people to 38 and, at the other end of the scale, from 15 to 400 with offices worldwide.

Jason spins traditional coaching and mentoring on its head to deliver a service driven by his own business success… He is extremely enthusiastic about his work and has an honest straight-down-the-line approach… Jason is a great strategic ally for SMEs.
Laura PearceFounder & MD, Strand
Jason is one of those ‘stand out’ kind of people. He’s massively driven and always delivers. He is brutally honest and transparent in the way he deals with people which builds success for his clients and team.
Alistair BryanCEO, Bray Leino
What I like about Jason is, he has actually been there and done it with his own companies and really understands every aspect of growing a business.
Csaba KantorBusiness owner
He is very level headed and has a good business brain, so by putting two heads together you can achieve much more than you would have done on your own. Have a coffee with him, you won’t regret it!

It’s felt like a full business ‘makeover’, and I am now in a much better position both professionally and financially than I was a year ago.

Let’s see if the fit is right

It starts with a chat — coffee, Zoom or phone, 45 minutes, no charge and no pitch. Tell me what’s going on and what you’re trying to achieve. If I’m not the right person for you I’ll say so, and you’ll still come away with something useful.
