Radioul Oy

Empowering customer success through cutting-edge technologies

Radioul was established by ten former Esju employees, driven by a shared commitment to extending the tradition of radio design excellence since 1991. Our choice of name, ‘Radioul,’ draws inspiration from Oulu, renowned as the birthplace of radio, where ‘Radio’ combines with ‘Oulu’ to create ‘Radioul.’
