Againn is a Bangalore-based company that offers an online loyalty service, allowing users to earn and redeem reward points across multiple stores. It operates on a revenue-sharing model with merchants, charging a small percentage of transaction amounts. The charges vary depending on whether users are earning or redeeming points, as well as the industry segment of the merchant partner. There are no setup or subscription fees. Againn aims to improve customer service by treating each customer individually and differently. Users can register by giving a miss call and seamlessly earn and burn points at any of Againn's merchant partners. The platform integrates with merchant websites and rewards users for completed sales. Additionally, merchants can reward users for sharing their content on social networks. Future plans include introducing SMS gateway-based loyalty programs for offline retailers.
