AI and SaaS companies building their backend typically stitch together single-purpose tools for authentication, payments, user data, and analytics. This creates multiple accounts, scattered data, and costs that compound as the business scales. Teams end up writing and maintaining custom business logic and webhook handling just to keep these separate systems in sync. This hidden complexity makes it harder to reach the insights and full picture of the business they actually need.

tiun provides one integrated system covering authentication, payments, a customer database, and AI analytics, designed as an ecosystem of services that work together from the start. Authentication includes sign up, login, logout, multifactor auth via SMS, email, and social SSO, plus user button and profile components. Payments support one-time, subscription, and usage-based billing with pre-built checkout components, and tiun acts as Merchant of Record handling tax compliance and chargebacks with monthly payouts. The customer database keeps subscription status, session and event tracking, transactional emails, invoice history, and plan management in sync without custom sync logic, exposed through a single queryable data API. Integration is done by installing tiun's skills and connecting its MCP server so an AI agent can handle setup, avoiding custom webhook or backend logic.
