No one should be stitching together five tools just to launch and monetize a product

It's 2026, and building an app has never been faster. But the moment you need authentication, payments, subscriptions, usage-based billing, customer data, and analytics, everything becomes complicated again.

You connect one tool for users, another for payments, another for product data, and then have to keep all of them in sync. This shouldn't be the part that slows builders down.

That's why we're building tiun. One backend for AI and SaaS builders that brings authentication, payments, customer data, and analytics into one system.

You can create different pricing models, charge based on usage, generate invoices, manage customers, and understand how people use your product without maintaining a fragmented stack.

tiun also acts as your Merchant of Record, handling payment processing, tax compliance, and chargebacks.

As more products are built by solopreneurs and small teams, we think the infrastructure behind them needs to become much simpler too.
