Jonathan McHarg Consulting Limited

I've run the businesses I advise.

Thirty years in IT leadership — disaster recovery at Exxon Mobil, and a key part of building one of the UK's largest hospitality IT companies. Today I work with businesses across Dorset, Hampshire and further afield on their technology, their security, and the way they run.

About Jonathan

I've spent my career in IT — technical roles first, then leadership, then consultancy. The thread running through all of it is that I've been accountable for the outcome, not just the advice.

Seven years consulting for Exxon Mobil taught me to design systems that hold up when the stakes are high, working alongside Microsoft on disaster recovery and security. Helping build TMB Group into one of the UK's largest hospitality IT companies taught me what it actually takes to grow one — the hiring, the structure, the quarter that doesn't go to plan.

That second part is why the coaching works. I'm not teaching a framework I read about.

Two different businesses, one way of working. On the coaching side there's no long-term contract — you buy a month at a time. On the IT side you get an itemised statement every month, and the fee only changes when the numbers say it should. I'd rather earn it than tie you in.
