The problem

Enquiries arrived on WhatsApp at all hours and in two languages. A small team couldn't answer fast enough, and details were lost between chats.

What we built

  • A WhatsApp agent that replies in the customer's language — English or Hindi
  • AI qualification with the right follow-up questions
  • Automatic CRM records for every qualified enquiry
  • Personalised PDF brochures generated and sent in the chat
  • Conversation state stored for analytics and hand-over
