Stream Sync Engage

A no-code platform for sending targeted, real-time messages to your app users: notifications, surveys, product tours, voicemail, and slideshows. Install the snippet, design the message, schedule the send.

What is Stream Sync Engage?

A live engagement engine built for modern apps that want to go beyond static push. Three ideas, one platform: stream events in real time, keep every device in sync, and engage users with formats that earn a response.

[01/stream]
STREAM

Continuous, real-time delivery. Engagements flow to the right user the moment events unfold, not in a nightly batch.

[02/sync]
SYNC

Context, state, and devices stay aligned. Smart routing reads what the user is doing and reconciles offline cleanly when they return.

[03/engage]
ENGAGE

Built for two-way interaction. Surveys, voicemail, guided tours, and slideshows. Formats that earn a response, not just a glance.

Built for Real-Time Engagement

Real-Time Delivery
