Jupiter should start a service like Axis bank ‘grab deals’. To my knowledge it looks like an affiliate cashbacks service similar to cashkaro and gopaisa .
I think I may have posted about the same before,(couldnt find it now).
Jupiter can provide these extra cashbacks when users purchase through the affiliate links inside the jupiter app. To track if purchase is done or not, Jupiter can mandate users to purchase via Jupiter’s debit card.
From my point of view these extra cashbacks on using debit card may force users to use the cards more than UPI and they will get a satisfaction having an extra reward.
Just a suggestion.
