Feedback & surveys
Why we built these
No email wall, no trial, no account. Use the tool, take the result, leave.
Nothing you type is sent to a server or stored. The maths happens on your device.
Rupee-first calculators and WhatsApp-first workflows, because that is where our customers are.
We build customer engagement software for WhatsApp. These tools solve the small problems around that work — generating a link, pricing a campaign, costing your returns. If they are useful, you will know where to find us when the bigger problem shows up.
When a tool stops being enough
A link needs an inbox behind it. A survey needs somewhere to send it. A QR code you have already printed needs to stay changeable. RateUp is the platform these tools point at — WhatsApp messaging, automation, feedback and loyalty in one place.
