tiun
Auth, billing, and payments for AI and SaaS builders
Visit website →About
tiun is the AI-native backend platform that unifies authentication, payments, customer database, and analytics into a single system. Instead of stitching together Stripe, Auth0, Segment, and a dozen webhooks, AI and SaaS builders get one coherent layer designed to work with agents from day one.
The platform acts as merchant of record, handling tax compliance, chargebacks, and monthly payouts. Pre-built checkout components drop into your app as overlays, so users never leave your page. Every login, purchase, and session is tracked at the profile level — no syncing between tools.
tiun's MCP integration lets AI agents manage billing, query customer data, and trigger analytics without custom backend logic. The AI analytics layer surfaces who's signing up, who's paying, and where value is created — giving product, engineering, and marketing one source of truth.

Why we picked it
Most AI builders cobble together Stripe, Auth0, and analytics separately. tiun collapses that stack into one layer with native MCP support — the kind of infrastructure thinking that saves weeks of integration work.
