In Indian real estate, a buyer usually enquires on 99acres, MagicBricks, Housing and more at the same time, and the broker who replies first tends to get the site visit. Most brokers are out on visits all day, so many leads wait hours for a reply.
Genluno replies to those portal leads on WhatsApp in about 60 seconds, in English, Hindi or Hinglish. It asks about budget, locality and timeline, and books the site visit.
