Why teams connect Braze and Kustomer

Sync what happens in Braze with the customer records in Kustomer, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Braze holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Subscription Groups, Content Blocks, Users, Custom Attributes in Braze to Messages, Companies, Custom Objects (Klasses), Users in Kustomer with bi-directional, real-time sync. Activity and record changes in Braze update the matching contact or account in Kustomer, and CRM data flows the other way wherever Braze can store and use it.

Common use cases

  • Sync CRM and billing attributes onto Braze user profiles so lifecycle campaigns target accurate plan and status data.
  • Push product usage events from a database or warehouse into Braze to trigger onboarding and retention journeys.
  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools

Where Braze runs outreach

Prospects, sends, and replies sync into Kustomer, keeping lead status current without manual imports.

Where Braze supplies contact or company data

Enriched fields land directly on records in Kustomer, and refreshes keep them from going stale.

Where Braze processes payments

Charges, refunds, and subscription changes appear on the account in Kustomer, so revenue context lives with the relationship.
