For the 12th year in a row, we organized (The Conference known as) Conversion Hotel. #CH is a 3-day event on the beautiful island of Texel in the Netherlands. Passionate digital optimizers spend the weekend sharing their knowledge, experiences and skills in the field of Product, UX, Marketing and Data.
