tiun provides a unified backend service for AI and SaaS products, combining authentication, payments as a Merchant of Record, customer data, and analytics.
What the product does and how it is positioned
tiun is an all-in-one backend platform created for AI and SaaS applications. It replaces disjointed third-party infrastructure by integrating user authentication, billing, customer databases, and analytics into a single service.
The platform includes pre-built checkout overlays and profile components, operates as a Merchant of Record to address tax compliance and chargebacks, and allows AI agents to assist with setup via Model Context Protocol integration.
Source-supported ways to use the product
Developers can set up one-time purchases, subscriptions, or usage-based billing using drop-in checkout overlays and Merchant of Record compliance.
