I began my career at BT in 1997, firstly BT Cellnet and then into BT Global Services across the UK and the Netherlands, gaining deep experience in mobile and enterprise technology and large-scale service delivery. Seeking a faster pace and more innovation, I transitioned into the startup and scaleup world—starting with Vidyo, a US-headquartered programmable video platform that was ahead of its time.

Vidyo quietly powered early versions of Google Hangouts, major Telehealth platforms, and video banking for HSBC and Barclays. Despite its technical edge, the rise of Zoom and BlueJeans—offering simpler, more user-friendly UX—left Vidyo outpaced in a rapidly shifting market and they were sold just before the Covid pandemic and the resultant boom in video/remote working

In 2018, I joined Nexmo, which proved to be a much stronger success story. Nexmo served as the developer glue for embedding programmable communications—SMS, WhatsApp, Voice,Video, Facebook Messenger—into modern customer engagement tools. When I joined, revenues were ~$60M mostly from SMS Marketing; we grew that to ~$1.5Bn through a mix of organic scale and acquisitions, ultimately leading to a $6.2Bn sale to Ericsson.

During my time at Vidyo and Nexmo (later as part of Vonage), I held leadership roles across nearly every aspect of Go-To-Market, including Sales Leadership, Direct and Indirect Sales, Alliances, Revenue Operations, Sales Enablement, and Product Operations. My final role before leaving post-acquisition was as Senior Vice President, reporting directly to the Group CRO/COO.

Today, I work fractionally with early-stage startups in Conversational AI and LegalTech—helping founders shape their GTM strategy, build scalable commercial operations, and accelerate early growth.

I’ve recently joined Automated Analytics as COO. If you’re not familiar with them, they are a multi award winning AI and Analytics business, HQ’d in Doncaster and Private Equity backed. The primary focus is helping businesses maximise their return on marketing investments. They do that by using AI and attribution tracking technologies in parallel, analysing everything from Google Ad Spend through to sales calls and offline conversion.

As with many businesses they’ve pivoted a couple of times on their journey but are now very much on the right track with extremely high top line growth and enviously high NRR.

Keeping it within Yorkshire, their underpinning in-house AI model was developed in partnership with the University of Sheffield, unlike the competition which typically rely on Google or AWS technologies
