tiun

tiun provides a comprehensive backend solution specifically designed for AI and SaaS companies, eliminating the complexity of managing multiple single-purpose tools. Instead of juggling scattered accounts, dashboards, and exponentially growing costs, you get everything in one unified platform.

Key features include:

• Authentication system with social SSO, multifactor auth (SMS, email), and ready-to-use components for sign up, login, and user profiles
• Payment processing with 2.9% + 30¢ transaction fees, supporting one-time payments, subscriptions, and usage-based billing
• Customer database that automatically syncs user data, subscription status, and transaction history without complex synchronization logic
• AI analytics providing complete visibility into user behavior, payment patterns, and product usage

The platform serves as your Merchant of Record, handling tax compliance and chargebacks while offering pre-built checkout components that keep users on your page. Advanced event and session tracking captures every user interaction at the profile level, giving you actionable insights across business, engineering, product, and marketing teams.

Integration is simple - install with a single command and let the AI agent handle the complex setup. No webhooks, no custom business logic, no maintenance headaches. Companies like Res Publica have seen 21% increases in paying users after implementing tiun's usage-based billing system.

Built with GDPR compliance and hosted in Europe, tiun transforms the traditional fragmented backend approach into a cohesive, scalable solution that grows with your business.
