BIO/ INTRO
I build the products and platforms that millions of people rely on without ever noticing: identity, fulfilment and personalisation, at the scale where the stakes are real and the complexity is unforgiving.
My career spans twenty years of product leadership across Tesco, Barclays, Sky, Motorola, Telefónica (O2) and Fidelity International, after an earlier chapter in brand and marketing leadership at Sony Ericsson. Across leadership roles and delivery engagements, that includes six FTSE 100 organisations (all in the FTSE 50 at the time) and three Fortune Global 500 companies.
Today I lead Tesco's identity platform, serving tens of millions of customer accounts across five markets.
Other engagements include two interim mandates at Vodafone (2012 and 2016), leading digital transformation and a self-service web platform serving 3 million customers under significant delivery pressure, and a critical global CRM programme ("Data Hub") for the UK Department for International Trade, underpinning the UK's £1.3 trillion FDI pipeline against Brexit-era deadlines.
A through-line worth naming: I've repeatedly been called on at genuinely consequential national moments, from Brexit-era trade infrastructure to pandemic-era grocery scaling, leading the product response both times.
I'm the author of Product Truths: Five Principles for Building Products That Work at Scale, and I write and speak on identity, platforms and AI, most recently opening Product Economics' Secure by Design webinar series. The best operators should be able to explain what they build and how, not just build it.

I help large organisations build products, platforms and systems that customers depend upon - at enterprise scale.
My work sits at the intersection of Product, AI, Identity, Trust and Enterprise Platforms.
The most valuable products are built when technology, trust and business strategy align behind a shared mission. It’s a principle that has shaped my career - and ultimately became one of the Product Truths I wrote about.

Speaking regularly on product at scale themes, including discussing Identity as a lever of organisational growth at CXFS26, and my recent guest appearance on Product Economic’s ‘Secure by Design’ series, in October 2026, discussing the intersecting themes of data, privacy and trust:

Cost to Catalyst, ChangeMakers Club (AI adoption)
The Security Shift, ChangeMakers Club (identity for AI agents)

>Looking ahead:
The challenges I’m most interested in solving are focussed on helping organisations navigate one of the biggest shifts in modern business: building trusted, AI-enabled products and platforms. That can scale sustainably, create commercial value and earn lasting customer confidence.
I’ll be a guest on the Queen Mary University Cyber Security Podcast on 13 November 2026, discussing the latest challenges in cyber security and resilience.
