At Oxford Product Design (OPD) we’re on a mission to make things better. Better for the products we design, the clients we work with, our people working here, our planet, and everyone we connect with along the way.

Our exceptional team of professional problem solvers work with both start-ups on ground-breaking new ideas, as well as some of the world’s leading brands on category-defining products that improve how we humans live and work.

As innovators we are curious, experimental, creative and passionate. But our pragmatic, precise approach and highly technical expertise mean that manufacturability and risk management are at the core of everything we do.
