What is EnSync?

EnSync is partner integration infrastructure for B2B platforms. We enable self-service partner integration via developer portals and bidirectional event delivery through persistent connections, so your partners can integrate in minutes instead of weeks. Whether you’re building a new product that needs to be integration-ready from day one, or scaling an existing platform to 100+ partners, EnSync provides the infrastructure to make partner integration seamless.
Messaging, Not Broadcasting: EnSync works like messaging, not broadcasting. When you publish an event, you specify which partners should receive it—just like sending a WhatsApp message to specific contacts. Even if multiple partners subscribe to the same event type, they only receive events explicitly addressed to them. This ensures multi-tenant data isolation and privacy.

​
Why We’re Building EnSync

We’re building EnSync because partner integration shouldn’t be a bottleneck to growth. We believe products should be built integration-ready from the start. Whether you’re launching your first partner integration or scaling to your hundredth, the infrastructure should be the same. We’re creating the tools that let you build once and scale infinitely. We’re solving for:
  • New products that want to be integration-ready from day one
  • Growing platforms scaling from 10 to 100+ partners
  • Engineering teams spending 30%+ time on partner support
  • Manual partner setup taking 2-4 weeks per partner

​
