THE CUSTOMER ACTIVATION PLATFORM

Capturing opt-ins is hard

We make it easy

Whisp bridges the gap between customer interaction and customer activation by turning unknown visitors into verified, reachable customer relationships. Activate instantly across SMS, RCS, mobile wallet, loyalty, and CRM.

Most brands generate traffic. Few capture customers.

Most Engagement Never Becomes Activation

Forms interrupt the moment before brands capture consent or reachability.

Infographic explaining how most digital interactions go nowhere, highlighting that people tap, scan, click, and engage daily but rarely make real connections. It illustrates how forms interrupt moments, create friction, and lead to drop-off, with statistics showing high abandonment rates and lack of real engagement.

Most Platforms Activate After Opt-In. Whisp Captures the Opt-In Itself.

Whisp closes the gap between engagement and activation.

Turn anonymous visitors into known customers

Whisp captures verified mobile opt-ins the moment people engage, transforming unknown visitors into real, reachable customers you can activate across SMS, RCS, loyalty, wallet, and CRM.

An infographic explaining how Whisp works, with four steps: interact with a QR code on a smartphone, send a pre-filled message, capture verified mobile opt-in data, and activate cross-channel engagement. It also includes statistics showing 95% web form abandonment, 45-55% opt-in completion, 100% verified cell numbers, and three times higher engagement.
