EMBEDDED INTEGRATION PLATFORM

Every integration in your backlog is a customer you can't satisfy.

Stop burning 20–40% of sprint capacity on connector maintenance. Fastn gives you a shared integration runtime so every new connector doesn't become permanent engineering ownership.

What you can build with Fastn

Fastn turns integrations from engineering projects into platform configuration—including the long tail of bespoke customer setups.

Production-hardened connectivity

Stop rebuilding retries, rate limits, and error handling for every connector. API changes don't automatically become incidents.

Customer self-serve

Customers configure in a guided flow. Customer Success can see status and assist without engineering. White-labeled so it feels native to your product.

Multi-tenant credential isolation

No cross-tenant risk: credentials and configs are isolated by design. Audit-ready out of the box.

Three steps to connect your ecosystem

1

Define the integration

Describe the target system, entities, and requirements—including custom objects, event rules, and edge cases you know are coming.

2

Embed the customer experience

Use the Fastn SDK to ship a native, white-labeled flow where each customer authorizes their own instance with isolated credentials, multi-tenant by design.

3

Run it in production—with guardrails

Your integration is live with retries, rate limits, and error handling already in place. CS has visibility into connection status. Engineering gets observability without building it from scratch. Go live in hours, not weeks.
