Your business software, built to measure.

Web applications that adapt to your business, not the other way around.

Your company has specific needs that no off-the-shelf software can fully cover. A CRM built for your sector, a SaaS platform, a members area, a management dashboard, a marketplace or an internal tool — we design and develop custom web applications that integrate with your existing processes and grow with your business.

Our team masters the full technical stack: TypeScript, React, Python, Node.js, PostgreSQL. From architecture to cloud deployment, every decision is made to maximise the performance, security and maintainability of your application.

From MVP to scalable platform: we support you at every step.

We work in iterative sprints with regular demos. You see progress in real time, validate each feature, and we adapt quickly based on your feedback. No more projects delivered 6 months late and already obsolete.

Security and third-party integrations included from the start.

Every delivery includes an OWASP security audit. Stripe, HubSpot, Salesforce, Twilio or any business API — we connect your tools for a smooth, silo-free ecosystem.

FAQ

Frequently asked questions

When should I opt for a custom application?

When no-code solutions or standard CMSs are no longer sufficient: complex business logic, multiple integrations, high volumes, very specific user experience, or need for an advanced members area.

What technologies do you use?

TypeScript, React/Astro on the front end, Node.js or Python (Flask/FastAPI) on the back end, PostgreSQL/Redis for data. We choose the stack best suited to each project and your constraints.

Do you offer maintenance after delivery?

Yes, we offer monthly TMA (Third-Party Application Maintenance) contracts covering updates, security patches, minor improvements and dedicated technical support.

What is the budget for a custom application?

The budget varies by complexity: a simple application starts around €3,000, a full SaaS platform can exceed €15,000. Contact us for a free estimate based on your needs.
