About Rehab

Rehab is a digital innovation agency delivering growth for the world's biggest brands through emerging technology. We’re based in Old Street, London and currently have a hybrid model for working both remotely and in the office.

We de-risk innovation through Triage, a sprint process that helps us research, ideate, identify and create services, products or experiences that give our clients an unfair advantage.

Your values are your own, but we believe that shared mindsets and behaviours are important in collaboration and moving forward in the same direction. To thrive at rehab, you'll need to have a mix of these: leading rather than following; feeling comfortable with unknowns; learning constantly; using initiative and being a positive culture carrier.

We work with global clients including Nike, Google, Meta, Disney, LEGO and Spotify, among others. Through our work we’ve been honoured with industry awards including an Emmy, Gold Cannes Lions, Deloitte Technology Fast 50, and Digiday.
