Based in the heart of Paris, Occi is a young French startup whose mission is to improve shopper experience by making it more customizable. Occi enables physical stores to access previously untapped data about what shoppers do inside the store. Who enters my store ? What product categories are they visiting ? What are the interests and needs of my customers ? We help retailers answer these questions by combining IoT, indoor geolocation, data fusion algorithms and AI. Founded in 2015 by two students from Ecole Polytechnique, Occi is a fast-growing startup that has already convinced international retailers such as Carrefour, Auchan or Galeries Lafayette.
