Whisperr

Whisperr is an autonomous customer retention platform designed for subscription SaaS, digital businesses, and DTC companies. It monitors customer behavior in real time, identifies signals associated with churn or disengagement, determines when an intervention is appropriate, drafts the message in the company’s voice, selects the communication channel, sends the intervention, and learns from the outcome.

Key capabilities: Whisperr processes customer events against more than 50 weighted behavioral markers and uses probability-based thresholds to trigger retention workflows. Supported workflows include cancel-intent recovery, inactivity re-engagement, win-back campaigns, and other behavior-based interventions. Messaging can be delivered through channels including email, SMS, push notifications, and in-app messaging. Teams can review, edit, or approve interventions through Approval Mode before moving toward greater autonomy. The platform is designed for self-service implementation, with a single SDK and automated onboarding that can take a business from setup to live interventions in under 30 minutes.

Results and differentiation: Unlike customer engagement platforms that require teams to manually build audiences, write copy, select channels, and schedule campaigns, Whisperr is designed to operate the retention process end to end while keeping teams in an approval and oversight role. In its Hotcard pilot, the vendor states that 30-day engagement retention increased from 35% to 47%, 90-day paying retention improved 32% versus baseline, and weekly manual retention work decreased from approximately 20 hours to under two hours.
