We do not start by coding. First we set a clear frame. Depending on the project, that takes two forms: - A precise quote, if your needs are already detailed. - Or a starting-block prototype, to validate the experience and priorities before a heavier investment. The point of this step is simple: see where time and budget go, and avoid misunderstandings.

It starts at €5,000 for a simple MVP. From there it depends on features, architecture, and the level of design. We give you a clear picture at scoping, so there are no surprises later.

On average an MVP is delivered in 6 to 10 weeks. More complex projects can take 4 to 6 months. We work in short sprints, so you see concrete results from the first weeks.

Each step is validated before we start the next one. That guarantees every euro maps to real progress (prototype, features, tests). You stay in control of priorities and trade-offs.

You are in the loop at every step: you validate, and we can change course if needed. No black box. The product has to match what you actually want.

Launch is only the beginning. We stay for maintenance, new features, and growth: bug fixes, additions, and preparing for more traffic.

The code is 100% yours. We work on secure repositories and you keep full access. You are free to continue with us, bring in your own team, or hand over to another partner.

We pick the stack that fits your project (React, Node.js, Next.js, TypeScript, PostgreSQL, and others). Our approach is pragmatic: we skip trendy tech for its own sake and choose what is reliable, secure, and able to grow.

You have a single point of contact (project lead or tech lead). Communication happens on Slack/Notion, with regular demos each sprint. You follow progress in real time, as if you had an in-house team.

That is planned from day one: we build a base that can grow. Adding features, connecting APIs, or preparing for more traffic is part of the cycle. Your product grows with you.

Yes. Personal branding and design system, as a two-in-one offer: the identity plus the system, so the site and the product stay aligned. As an extra option, complete personal branding with Yasmine El Khamlichi, our designer. Brand books are in the work section, so you can see how much that deliverable matters.
