Expertise Rooted in French TrustworthyAI Deeptech

AICET is designed and operated by Numalis, a French deeptech company recognized for its expertise in the reliability of high-risk artificial intelligence. Scientific rigor transferred to AI skills measurement, to provide large organizations with an enforceable benchmark.

Numalis: a French deeptech company
specializing in trustworthy AI

$

Born out of scientific research, Numalis specialises in the explainability and robustness validation of AI using formal methods. This branch of theoretical computer science leverages mathematical logic to prove the validity of the information produced by an AI.

$

Unlike traditional testing, which is limited to statistical evaluations, Numalis explores the entire realm of possibilities of an AI model using its Saimple software. The objective: to detect the maximum level of disturbance at which the model's reliability is guaranteed.

From Saimple to AICET: one conviction, two objects

By supporting the largest industrial players with the technical validation of their algorithms for MORE than a decade, Numalis has identified a major blind spot: the reliability of the human skills operating these systems. Securing the code is no longer enough; adoption must also be secured.

AICET was born from this observation: applying to AI skills measurement the same scientific and mathematical rigor that Saimple applies to model validation. One conviction: you cannot steer an AI transformation without a rigorous, auditable measurement neither of the systems OR EVEN of the skills.

Arnault Ioualalen

From scoring to AI Strategy

Holding a PhD in AI, Arnault Ioualalen is a leading figure in trustworthy AI in France. Founder of Numalis in 2015 and subsequently of AICET, he holds the conviction that the reliability of AI systems and of the human skills that operate them stems from the same scientific requirement: measurable, enforceable, aligned with standards.

His normative commitment is concrete and public: he is the lead editor of the international standard ISO/IEC 24029 on AI robustness, a direct contributor to AFNOR SPEC 2401 (the French reference framework for measuring AI skills) and to the AI Act, an international expert on ISO/IEC trustworthy AI committees, and an active AFNOR member.

« Notre mission chez Numalis est simple : transformer l'incertitude liée à l'IA en une fiabilité absolue, vérifiable et conforme aux exigences de demain. »

Numalis Achievements — Three flagship cases

Numalis's experience in validating critical AI has been built alongside major players in regulated sectors. Three illustrations.

Challenge

Validate the reliability of AI vision algorithms for the dashboard displays of the European ERTMS signaling system, in a domain where safety is an absolute requirement. The deep learning ‘black box’ effect renders traditional certification methods inoperable.

Approach

Application of Saimple software (formal methods) to mathematically explore the model’s space of possibilities; injection of perturbations (blur, pixel modifications, watermarks) to detect invisible vulnerabilities.

Result

Automation of ERTMS DMI screen certification, major time savings in the validation phase, 7-year operational partnership, equity participation from 574 Invest (SNCF Group fund) in 2026. Numalis becomes a building block of the global AI railway certification standard.

Our Methodological Rigor

Our conviction

Measuring AI skills is an act of scientific engineering, not a communication exercise. Designed and operated by a deeptech company recognized for the reliability of critical AI: AICET is a standard, not just a barometer.
