Rooted in Science

Behavioral AI designed with rigor, built for trust, and fully controlled by humans

At Stern Tech, we develop behavioral AI grounded in science, transparency, and ethics to help professionals make better-informed decisions while keeping humans at the heart of the process.

By design, our systems are decision-support tools.
They produce probabilistic and informational outputs, make no autonomous decisions, and do not replace human judgment, expertise, or user responsibility.


Where artificial intelligence meets cognitive science

At Stern Tech, “behavioral AI” is not a marketing claim: it is a scientific position.

Understanding human behavior requires far more than simple pattern detection. It requires rigor, context, and an interdisciplinary approach. Our technologies are developed at the intersection of artificial intelligence and cognitive science, relying on established scientific frameworks to analyze behavioral signals in a contextual, probabilistic, and explainable way.

Our scientific foundations include:

Mathematics and statistics

Mathematics and statistics
measurement, modeling, uncertainty management

Computer science and algorithms

Computer science and algorithms
robustness, reproducibility, clarity, performance

Sociology

Sociology
social context, norms, group dynamics, social signals

Psychology

Psychology
cognition, affect, decision-making processes

Neuroscience

Neuroscience
perception-action loops and sensorimotor foundations

Linguistics

Linguistics
language as behavior: meaning, pragmatics, interaction

This interdisciplinary approach enables us to move beyond opaque predictions and build AI that helps understand, contextualize, and support human judgment without producing automatic verdicts about individuals.

A scientific foundation strengthened by academic partnerships

Stern Tech maintains long-term research collaborations with leading public academic and research institutions, including the CNRS, Sorbonne University, ENS Paris-Saclay, the Centre Borelli, and the Institut Carnot Cognition.

Our research partnerships are based on formalized agreements that ensure rigorous methodology, robust evaluation protocols, and a scientifically grounded approach.

Academic partnerships strengthen our scientific approach, while regulatory compliance remains independently managed by Stern Tech and its clients.


A Scientific Advisory Board to challenge and strengthen our choices

Stern Tech relies on a multidisciplinary Scientific Advisory Board that supports the development of its technologies, challenges its methodologies, and helps strengthen their scientific robustness.

Important clarification: the Scientific Advisory Board provides scientific and methodological insight. It is neither a legal or regulatory certification body nor an institutional validation binding the organizations with which members may be affiliated.


Responsible AI by design: transparent, compliant, and human-controlled

Stern Tech solutions are developed and deployed according to a responsible AI framework aligned with European expectations:

  • Decision-support tools controlled by humans
  • No automated or autonomous decisions produced by the systems
  • Priority given to explainability, transparency, and documented evaluation
  • When personal data is processed: compliance with GDPR principles, including purpose limitation, implementation of appropriate safeguards, and respect for individuals’ rights
  • Governance aligned with the risk-based approach of the EU AI Act, including documentation, oversight, and accountability requirements where applicable

This framework does not limit innovation: it forms its foundation, enabling the development of credible, responsible, and sustainable behavioral AI.
