tiun.

Excited to hunt tiun today. @tiun is the all-in-one backend for AI and SaaS builders who want to launch and monetize their products without stitching together multiple tools for authentication, payments, billing, customer data, and analytics. Instead of combining Stripe, Clerk, a separate database, invoicing software, and multiple analytics tools, tiun brings the entire customer and revenue infrastructure into one platform. What stands out here: • Auth & User Management: Drop-in authentication without building from scratch. • Flexible Billing: Manage subscriptions, one-time payments, or usage-based billing. • Handles invoices, global taxes, and Merchant of Record (MoR) operations. • Single Dashboard: Track customers, transactions, and product activity in one place.

👋 I’m Nikolaos, one of the founders of tiun. AI tools now let one builder ship what once required an entire product team. The obvious gain is speed, but turning that product into a business still requires several systems that were never designed to work together. We saw this across 150+ founder conversations: You build the core product in days, then spend weeks connecting auth, payments, billing, and analytics. The Problem with "Best-in-Class" Tool Stacks: ❌ Sync Chaos: Every tool brings its own customer ID, billing state, event model, and retry logic. Your code ends up stuck keeping them in sync. ❌ Broken Logic: A subscription renews in your payment provider, but a failed webhook leaves your database unchanged—so a paying customer suddenly loses access. tiun removes that coordination layer. Authentication, payments, billing, customer data, and analytics run in one system, connected from the very first transaction: ⚡ All-in-One Infrastructure: Subscriptions, one-time payments, usage-based billing & Merchant of Record (MoR) services out of the box. 🔄 One Customer Context: Account and commercial state stay connected across the product, without another sync layer to maintain. 🚀 Go Live in Minutes: Connect tiun and delete weeks of redundant backend work from your roadmap. tiun isn't another isolated auth tool or payment dashboard. It is one unified system for shipping and monetizing your product. We'd love your feedback! Give tiun a spin and tell us: Which part of turning a product into revenue still feels harder than it should? 👇

Super interesting idea to combine MoR with auth and analytics. I think this is going to be huge. Do you have any plans to go into storage/db so tiun would be the only platform you need to build an entire startup? 👀

Interesting solution! Congrats for the launch! Can you give some details on the auth and the db limits/cost and also scalability? Is there a limit after which there are different costs compared to a simple db and x nr of users? Also on the payment - how can you manage to offer such good rates compared to the alternatives? Can you give some details on how the payments are sent and if you use a PSP in the backend? I see hosted in Europe - any details you can provide on this? Again - awesome and ambitious product! congrats for the launch.
