Atendio: WhatsApp AI assistant that answers, books and sells 24/7

Hi Product Hunt! I'm Carlos, founder of btodigital, a digital agency with teams in Medellín and Spain. For years we ran ads for clinics, stores and service businesses, and we kept seeing the same pattern: the ads brought WhatsApp conversations, and many went cold because nobody could reply in time, especially at night and on weekends. So we built Atendio. It runs on the official WhatsApp Business Platform with the business's own number. The AI answers with the information each business gives it (prices, hours, services, policies), books appointments, and passes the chat to a person in a shared inbox when needed. For clinics, the assistant never diagnoses: it informs, answers admin questions and books. Plans start at US$49/month with the AI included and unlimited users, and Meta bills WhatsApp messages directly to the business, with no markup from us. There's a 14-day free trial. I'd love your feedback, especially from anyone selling or giving support over WhatsApp.
