Mr Digital

Brighton and Hove, United Kingdom · Team 11-50 · 6 services

Stop renting tactics and start building a revenue engine. Mr Digital is a Growth Architecture Partner for ambitious brands in Hospitality, B2B, and eCommerce. We exist to solve the broken agency model because most businesses are tired of the traditional approach defined by hourly billing, scope creep, vanity metrics, and junior staff learning on the client's dime. The Mr Digital difference lies in our refusal to operate like a typical vendor. We have replaced the "time-and-materials" model with a Fixed-Fee Growth Partnership. This means you pay one fixed monthly investment to handle the entire digital stack, Strategy, Web, SEO, Paid Media, and Creative, ensuring no surprise invoices. We prioritise revenue over reports, measuring success strictly in "£ Revenue Influenced" rather than just traffic; if it doesn't impact your P&L, we don't do it. Our clients benefit from proprietary technology, gaining real-time transparency via "The Performance Tracker," a live dashboard that replaces static PDF reports. Our impact is proven, with over £300M+ in revenue influenced for partners and deep expertise in Hospitality (RedCat Pub Company), Professional Services, and eCommerce (Splesh). Our engagement model is built on diagnosis before prescription; all partnerships begin with a Strategic Blueprint to identify revenue leaks before moving into high-velocity execution.Read more
