In 2018, Koen Broos himself experienced tinnitus and hyperacusis. This experience profoundly changed his life: work, hobbies, and social contacts came under pressure. He quickly noticed that the standard response — "you just have to learn to live with it" — offered little comfort, especially combined with long waiting times and a lack of specific help. Over time, Koen found ways to understand what tinnitus is, how it develops, and how to approach it differently. Now, the condition no longer affects his life, and what once seemed impossible is once again possible. From this personal transformation, Tinzo was created: an app that does not eliminate tinnitus but helps to push it to the background and experience space.
