From business model to hosting, every piece is designed so your product sells, grows and stays yours.
Pricing, launch scope and the cost of each user are worked out with you before any code, so the product makes money from its first subscribers.
Accounts, sign-in, roles and emails are in place on day one, and nothing needs rebuilding when the product takes off.
If your software sells by subscription, plans, free trials, invoices and payment reminders run on Stripe from launch.
Used in-house, the software connects to your CRM, accounting or ERP, and data moves between them without being retyped.
Revenue, churn and activation stay within reach, so every decision rests on current numbers.
AI features enrich the product without inflating the bill, through caching, a model matched to each task and per-user quotas.
Everything that runs your product is in your name, monitored and backed up, and you decide who develops it next.
Six building blocks assembled around Next.js, chosen so a product that launches small can grow large on the same foundations.

In September 2026, Shopify announced it was dropping React Native to rebuild its mobile apps in Swift and Kotlin, with the help of AI agents. The decision reopens a question many projects thought settled, the choice between a native app and a cross-platform one. This article breaks down what a mobile app costs, what AI changes in that cost, and the criteria for deciding on your own project.
SaaS & product
A founder who is not a developer can build their SaaS alone with AI and no-code tools, partner with a CTO, or hand development to an outside provider. Each of these approaches commits the founder's time, money and decisions differently, and each suits a specific stage of the project, from the prototype to the growing product.
