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 customer connections that power your marketing stack. Activate instantly across SMS, RCS, mobile wallet, and CRM.

Think about it, without a verified opt-in, your marketing stack has nothing to activate

Most Engagement Never Becomes Activation

Forms interrupt the moment before brands capture consent or reachability.

It illustrates how forms interrupt moments, create friction, and lead to drop-off, with statistics showing high abandonment rates and lack of real engagement.

Your marketing stack can’t activate people it can’t identify

Whisp turns anonymous interactions into verified, reachable customer connections your CRM, messaging, and loyalty platforms can actually activate.

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.
