London

Jon is an expert in data protection and privacy, AI, technology contracts, and consumer law. He generally represents clients from the retail and consumer or social media and technology sectors. His work often also involves a significant regulatory element.

“I’m happy to get off the fence and offer advice on practical risk”

“I work closely with many European and US firms, and bring deep expertise from 26 years of practice in data protection, consumer, and contract law. This experience enables me to get to the root of an issue quickly and provide a practical way through.

I’m happy to go beyond purely technical or legal answers, get off the fence, and offer advice on practical risk. Clients appreciate this friendly, unstuffy, solutions-oriented approach, which I’m able to take because I’ve often worked on similar issues for other clients.

I try to develop one on one relationships with clients beyond a work agenda. I like to invite them to events or dinners where we can network socially and, even when we don’t have active matters for them, I’ll send them information on developments they'll find useful.”

Jon’s recent work highlights:

Data Protection Audit for a major global hotel chain.

Reviewing major contracts for a multinational insurance company from a data protection risk perspective.

Advising one of the world’s largest wine and spirits sellers on data collection and user journeys across multiple brands as part of a review of their marketing strategy.
