How we work
We step in where the programme is under pressure,
not wherever the catalogue says.
Specialist team
Simulation, prototyping, testing, certification or engineering reinforcement embedded in your team to accelerate a specific phase.
Managed service
We take on a full service — technical office, simulation, test bench, validation — with clear owners, SLAs and follow-up.
Turnkey project
From concept to delivery. Our own Engineering Lab to design, integrate, validate and deliver prototypes, demonstrators and short-run production.
Multidisciplinary capability
Engineering, software, validation and security in a single team.
Support for critical systems
Procedures, traceability and coordination for demanding milestones.
Testing and validation
Simulation and testing of what we develop and what gets certified.
Confidentiality and rigour
Security and information access aligned with the programme's environment.
Certifications and approvals
- ISO 9001
- ISO 14001
- ISO 27001
- ISO 22000
- ENS
- Approved NATO supplier

Frequently asked questions
What we're asked before
the first meeting.
Engineering, mechatronics, electronic systems design, supply of prototypes and technology demonstrators, Smart Factory and PMO. We combine knowledge, experience and technology to deliver measurable impact in aerospace, naval, mobility and space.
Yes. We have a workshop (Engineering Lab) with the capability to design, integrate, validate and supply prototypes, technology demonstrators and short-run production products, based on materials and process specifications.
Our model for defence is based on providing knowledge, competence and experience across several technology domains linked to the dual use of products and services, guaranteeing technological sovereignty and compliance with the strictest security requirements.
We support the full journey from the data foundation to operating models in production: we review the architecture and manage MLOps and LLMOps platforms across the model lifecycle. Notable use cases: decision support and predictive maintenance.
Yes. We support the design, deployment and operation of secure digital platforms based on open technologies and market standards, reducing vendor lock-in and modernising existing systems towards cloud native and hybrid architectures, with cross-cutting cybersecurity.
Yes. We work turnkey or embedded within internal teams, with flexible collaboration and clear deliverables, applying rigorous management and monitoring methods on programmes with high compliance requirements.
