Decathlon, one of the world's largest sports retailers with 1,700+ stores globally, needed to scale customer support across a catalog of 10,000+ products. Their team was overwhelmed answering repetitive product questions, with response times reaching 4+ hours during peak periods. We implemented Chatty's AI chatbot, which learned their entire product database overnight — including specifications, compatibility charts, and sizing guides. The AI now handles 2,000+ conversations automatically with a 96.6% resolution rate, generates €10,964 in attributed revenue, and achieves a 9% chat-to-sales conversion rate.
