I help Thames Valley CEOs Scale Products, Teams & Performance

Straddling the M4 corridor, the Thames Valley hosts some of the world’s most influential tech campuses—from Microsoft & Oracle in Reading to Vodafone’s HQ in Newbury and the O2 Labs in Slough. I’ve spent the past decade helping companies turn cloud innovation into commercial advantage.

Over the past 27 years, I’ve built startups from idea to exit, scaled technology at bet365 to handle millions of concurrent users, enabled established companies transform outdated tech, launched new services at AWS, bootstrapped exciting new brands, and built the product direction and technical strategy for the world’s most complex immersive simulations.

Whether you’re scaling an enterprise SaaS platform in Reading, launching a 5G IoT venture in Newbury, or need seasoned leadership without the full‑time salary overhead, I deliver clarity, confidence and sustainable velocity across the Thames Valley or remotely throughout the UK.
