We have run the kind of business this is built for.
In a business where the same customers come back week after week, or quietly stop, the loss is invisible. Sales are in cash or on a terminal, names go into a register, and the regulars who drifted away last year never show up as a number anywhere. By the time you feel it, they are long gone.
When a business moves to digital payments, something changes. The payment rail already knows the phone number of every paying customer. The data is sitting right there. The only question is what you actually do with it.
Retainx is the answer we wanted. It auto-enrolls every paying customer, writes personalized WhatsApp messages that reference the actual things people bought, measures who came back, and tells you in plain English what is working and what is not.
We built it on the card rails small businesses already use, with UPI for India built in. We built it on WhatsApp, SMS, and email because that is where customers already are. We kept the hosting predictable because costs matter when you run a real business.
If you run a restaurant, a salon, a gym, a clinic, a corner store, or any business where the same person comes back, we built this for you. Try it free. If it does not pay for itself in ninety days, cancel. We email you the math the day before renewal, so the decision is always yours.
