Design backed by real technology experience.

39Design helps professional firms improve how they look, how they are found and how confidently prospects move from search to enquiry.

Matthew Southgate

More than a web designer.

Matthew Southgate is the founder of 39D and works across business technology, infrastructure, Microsoft 365, networking and cybersecurity. More than 20 years of relevant technical and business experience shapes how 39Design approaches websites: as operational business assets that need to be secure, credible, fast and commercially useful.

That technology background is particularly relevant for solicitors, accountants and other professional firms where trust, data handling and resilience matter.
