THE CUSTOMER ACTIVATION PLATFORM

Capturing opt-ins is hard

We make it easy ➜

Whisp captures verified mobile opt-ins the moment someone engages — turning taps, scans, and clicks into instant messaging connections. Activate instantly across SMS, RCS, mobile wallet, and CRM.

THE PROBLEM

Most interactions go nowhere

People tap, scan, and click every day — but most never become real connections. Forms interrupt the moment, create friction, and lead to drop-off.

THE SOLUTION

Capture opt-ins the moment people engage

No forms. No friction.

A simple message captures the opt-in instantly — creating a direct connection you can activate immediately.

Whisp captures mobile opt-ins at the moment of interaction — turning anonymous traffic into real, reachable connections.
