Everything About Our Case Studies

The full versions (precise metrics, architecture, sensitive data) are available under NDA. After an initial 30-minute conversation, our teams point you to the cases closest to your context.

Seven priority industries: Finance, Healthcare, Hospitality, Impact (social economy & public sector), Energy, Retail, Transport. Each has its own page with its cases, sector compliance and FAQs.

60% of the SDLC automated, ×10 deployment frequency, ROI in 9 to 18 months. On generative AI programmes: regulatory compliance (DORA, AI Act, NIS2) in 12 to 16 weeks.

A strict NDA before any detailed discussion, sovereign hosting (SecNumCloud, HDS) depending on the sector, and a dedicated DPO and CISO on every regulated engagement.

Yes. During our 30-minute demo, we tailor the scope to your industry, your stack and your challenges. No slides: real code, in a real pipeline.
