Home/Custom development

We code your tools. Not your dreams.

Showcase sites, SaaS platforms, mobile apps, internal tools. Architecture built to last, code written by the two founders, scalable without hidden costs. European hosting (GDPR), zero outsourcing.

[ What we build ]

Six types of project. One contact.

Showcase site, SaaS, mobile app, internal tool, e-commerce or no-code migration. We choose together the format that addresses your actual need.

01

SaaS Platforms

We build the business platform that doesn't exist yet. Authentication, Stripe payments, multi-tenant, real-time dashboards. Designed to scale from 10 to 10,000 users without rewriting a line.

02

Showcase & editorial sites

Custom showcase sites, editorial platforms, landing pages. Performant (Lighthouse 95+), impeccable technical SEO, integrated CMS. Built to convert visitors into clients.

03

Mobile applications

iOS and Android apps with React Native and Expo. Offline mode, clean sync, push notifications, integrated payments. App Store + Play Store publication included.

04

Internal tools

Back-offices, operational dashboards, business automations. We replace your Excel + Google Forms + Trello with one tool adapted to your process.

05

Custom e-commerce

Online stores tailored to your business. Stripe, subscriptions, multi-currency, stock management. Faster than Shopify, more modular than WooCommerce, no sales commission.

06

No-code migrations

Stuck on Bubble, Webflow or a limited no-code? We migrate to React/Node.js, preserve your data, multiply speed by 10. Zero downtime.

[ Stack ]

A modern stack. Built to last.

No trendy tech. Proven tools, maintained by active communities, easy for any developer to pick up. Your code stays readable and maintainable in 5 years.

[ Commitments ]

Four promises.

01

Zero outsourcing

The two founders code themselves. Your contact is the one who writes your code. For ambitious projects, we bring in a network of verified experts under our technical direction.

02

Transparent, modular pricing

No invoice surprises. We price module by module, detail every line. If the estimate is exceeded, we absorb the difference.

03

Your code, your property

Code delivered on your GitHub, your infra, your domain. If you switch providers tomorrow, you take everything. Zero lock-in, zero dependency.

04

100% European hosting

Your data stays in the EU. Scaleway Paris, Hetzner Helsinki, Vercel Frankfurt. GDPR native, encryption at rest, no transfers outside the European Union.

[ Process ]

Four phases to deliver.

1
Phase 1 · 1 week

Discovery & scoping

We understand your business, your users, your constraints. Custom workshop. Deliverable: a scoping document that becomes the project reference. Nothing starts before your validation.

2
Phase 2 · 2 to 4 weeks

Design & technical architecture

High-fidelity clickable mockups, technical architecture, database schema, stack choices. You see exactly what we'll build before the first line of code.

3
Phase 3 · 4 to 12 weeks

Sprint-based development

1 or 2-week sprints with a demo at every cycle end. You test, you validate, we adjust. No 3-month tunnel without updates.

4
Phase 4 · 1 week

Production & support

Deployment, monitoring, load testing, team training. We support you for the first 30 days in production, bug fixes included.

[ Quote ]

How we price projects

Everything is quoted, because no two projects are alike. But the quote is firm: firm price, firm deadline, scope written down before we start. No range that doubles along the way: what is written is what we invoice.
