A full front-end, back-end and design team takes your project from scoping to production. Budget and schedule fixed before the first line of code, then a usable version every two weeks.
Our application development expertise
Custom business applications
The internal tool that replaces shared spreadsheets and double entry: one source of truth, clear roles, a history of every action.
Client portals & member areas
Your clients track their case and find their invoices and documents on their own, without calling you or waiting for a follow-up email.
Multi-tenant SaaS & subscriptions
A product sold to many customers: data isolated per account, Stripe subscriptions, an architecture ready for your next 10,000 users.
Mobile applications
Installable PWA, React Native or native Swift / Kotlin to fit your constraints: the technology serves your project, not the reverse.
Authentication & permissions
Google, Microsoft or Apple SSO, two-factor authentication, role-based permissions, encrypted sensitive data, GDPR and European hosting.
API integrations & existing tools
Connected to your ERP, CRM, accounting software or Stripe, the app fills the gap between your tools instead of replacing them all.
Dashboards & reporting
Real-time metrics, exports and alerts: you see what is really happening in your business, without consolidating files by hand.
Data migration & takeover
Excel workbooks, an ageing database or in-house software: we take over your existing data and clean it up before go-live.

the tool that changes everything?
A call with one of our developers to scope your need and tell you what's realistic, in budget and in timeline.
Contact usThe questions we get asked the most.
We build custom web business apps, SaaS platforms, dashboards and back-offices, startup MVPs, and iOS and Android mobile apps. We handle the whole cycle: design, development, deployment. For a tailored business need, we go into detail on our business applications page.
The price depends on scope: a functional MVP doesn't carry the same budget as a full business application with several roles and integrations. We quote after a first conversation, once the scope is framed, to avoid nasty surprises. You'll find our pricing benchmarks on the pricing page.
A functional MVP can be delivered in about two weeks, while a complete business application usually takes 3 to 6 months. We break the project into sprints to ship usable versions along the way, rather than waiting until the end to show everything. The final timeline depends on the number of features and the integrations required.
The choice depends on usage: a mobile app makes sense if your users are in the field, need push notifications or an offline mode. A web app is preferable to reach a broad audience with no installation, accessible from any browser. In between, a PWA (installable web app) offers a good compromise, and we help you decide based on your case.
On the web side, we work with Next.js, React, Tailwind and TypeScript; on mobile, with React Native or native depending on the need. The backend relies on Node.js, Supabase and PostgreSQL. These are proven, high-performance and maintainable technologies that also make future changes easier.
We focus the MVP on its core value: the few features that prove the use case, without getting lost in the extras. Thanks to a modern stack and ready-made building blocks (authentication, database, hosting), a functional MVP can ship in about two weeks. It's often the first step of a future SaaS platform that we then grow through iterations.
Security is built in from the design stage, not bolted on afterwards: robust authentication, data encryption, role-based permissions. We comply with the GDPR and host data in Europe. Every sensitive feature is designed to limit access to the strict minimum.
An application lives and evolves after launch: that's the role of our Maintenance & Growth offer, covering monitoring, support and enhancements. We watch stability, fix what needs fixing and add features as your needs grow. In practice, you're not left alone once the product is online.
