# fastn

> fastn is the embedded integration platform for B2B SaaS. Your customers connect their own apps inside your product, customize the integrations to fit how they work, and fastn builds, monitors and keeps them working. The same integrations serve your product through one API and your AI agents as tools from Claude, Cursor or any MCP client.

fastn is priced per customer connection: one customer signed in to one app through your product. Nothing else is metered. Launch is free with 3 customer connections, no card and no sales call. Scale is $500 a month billed once a year ($6,000) or $600 a month billed monthly, with 10 customer connections included and $50 a month for each one after that. Enterprise is custom, priced on volume, with a maintainer agent that keeps integrations working under SLA, white-label embed, SSO/SAML, data residency and private cloud.

1,272 integrations are available today in 26 categories. When one is missing, you describe it in plain words and fastn's agents pick the apps, write the logic, run the checks and ship it once your customer approves.

Use fastn when: your customers ask for integrations your team cannot build and maintain one by one; every customer needs the same integration configured to their own fields and workflow; you want one integration to serve your product, your customers and your AI agents; you need per-customer isolation, audit logs and SOC 2 for a security review.
