About Cardencer
Small team. Senior engineers. Real products.
Cardencer SAS is an independent French software publisher headquartered in Marseille. We design, develop and operate our own software products — from the first prototype to production and long-term maintenance.
Security first
Least-privilege access, code review on every change and security best practices by default.
Product mindset
We build software people actually use, and we measure success by outcomes, not lines of code.
EU-based, GDPR-native
Headquartered in Marseille. Privacy and compliance are designed in, not bolted on.
Built to last
We own and operate everything we ship, so we build it to be maintained for years.
