The innovation ecosystem of ENS Paris-Saclay has been enriched by the creation of several start-ups resulting from the work of the laboratories' researchers or created by the school's graduates.



Hyperlex was created in 2017 by Alexandre Grux, a graduate of ENS Paris-Saclay, and Alexis AGAHI, a graduate of ENS Lyon with a master's degree in computer science.

Hyperlex has developed a set of technologies for automatic language processing, based in particular on statistical analysis, deep neural networks and supervised/unsupervised learning. Capable of identifying and understanding key information in contracts, Hyperlex's platform enables the analysis and validation of hundreds of thousands of multilingual documents in record time.

Hyperlex is aimed at all professionals who manage contracts - lawyers, financiers, sales representatives, buyers, HR managers...


The start-up FLYNAERO, created in July 2020 by Jean-Pierre Barbot, a teacher-researcher at the Systèmes et Applications des Technologies de l'Information et de l'Energie Laboratory (SATIE - ENS Paris-Saclay / CNRS), is based on an innovative solution. Computer-aided fluid mechanics is a computer tool for modelling fluid movements (liquid, gas), the properties of these flows (speed, pressure, temperature, etc.) and their interactions with their environment (heat exchange, chemical reactions, aerodynamic forces, aeroacoustics). The laboratory has developed and patented an aerodynamic modelling method that provides increased representativeness of the operation of flight simulators in so-called "sensitive" phases (take-off, landing, crosswind, etc.).


The start-up Kimialys develops and markets innovative surface chemistries applied to biosensors, increasing their sensitivity and specificity, and opening up new possibilities in in vitro diagnostics.
Dr. Claude Nogues, a CNRS researcher at ENS Paris-Saclay, has been working for 10 years on the development of Kimialys' patented technology. She is an expert in physics-chemistry, biophysics, surface and colloidal chemistry. Cyril Gilbert, technology investor at Jolt Capital, joined Claude Nogues to found Kimialys and accelerate the development of high-performance diagnostic solutions.

The start-up, which has been supported since October 2020 by SATT Paris-Saclay, signed a technology transfer contract for the maturation project in March 2021. It can now market innovative surface chemistries applied to biosensors, which will revolutionise the early diagnosis of diseases in the medium term. En savoir plus sur cette nouvelle étape.

The objective is to improve the reliability and traceability of manufacturing processes in industry through real-time factory location data and appropriate guidance.


CAPS, pour la mobilité aérienne individuelle pour tous

The start-up CAPS was created in July 2019 by Paul Cassé and Kevin Laouer, graduates of the Monabiphot (molecular, nano and biophotonics for telecomunication and biotechnology) master's degree at ENS Paris-Saclay, and Pierre de Chateaubourg, a graduate of the Ecole Normale Supérieure. Based on the observation that daily mobility is a factor in the attractiveness of cities that should not be a source of fatigue and stress, they have imagined a single-seat drone that flies from one terminal to another and can be booked via an online application. A fast, autonomous, inexpensive and environmentally friendly means of travel, which corresponds to a need since 70% of our urban travel is individual. Découvrez CAPS (interview vidéo).


Tinybird offers a range of vegan sweets, BonsBec, which are 100% natural, without flavouring, sweeteners or other additives that are harmful to health.

Magic Lemp

Magic Lemp, which specialises in consulting and training in the field of artificial intelligence, was created in 2018 by four graduates of ENS Paris-Saclay: Raphaël David Lasseri, Thomas Epalle , Marie Chupeau and Antonin Penon. This start-up has already supported several companies in R&D operations involving the most recent machine learning techniques, applied to a variety of problems including the semantic analysis of text documents, the automatic reading of musical scores, the understanding of the evolution of collective health needs, the recognition of movements in real situations from accelerometric data, or the acceleration of heavy numerical calculations.


AZmed is a French company founded in 2018 by Alexandre Attia (CTO), a graduate of the Master MVA of ENS Paris-Saclay, Elie Zerbib-Attal (CMO) and Julien Vidal (CEO), with the aim of improving the working conditions of doctors and contributing to the improvement of the quality of care. The first solution developed, Rayvolve, is a diagnostic tool based on artificial intelligence capable of detecting all types of fractures as well as various thoracic pathologies in standard radiography. Rayvolve software allows radiologists and emergency physicians to save time in interpreting examinations and reduce the risk of diagnostic errors. AZmed is the first French company to have obtained the CE mark for artificial intelligence software for conventional radiology.


Take a Seat was co-created by Grégoire Devauchelle, a graduate of the EEA department (2010-2014) at ENS Paris-Saclay.

Since 2020, offers a service for creating and managing digital menus accessible via QR code. The focus is on the ease of creation and customization of menus according to the brand image of their designers.'s "mission is to build a complete ecosystem that generates value for restaurant professionals and their customers."

DessiA is a startup publisher of software for industrial companies wishing to automate engineering design processes.

It was founded in 2017 by Pierre-Emmanuel Dumouchel (Supméca & PhD Paris 6) and Steven Masfaraud (normalien & PhD ENS Paris-Saclay), following a thesis carried out at the Centre Mathématiques et de leurs Applications (CMLA) which became Centre Borelli.

DessiA's technology is based on a mathematical and computational description close to MBSE (Model based system engineering) approaches. The software suite allows industrial clients to develop automation robots (engineering-bots) for routine tasks or tasks requiring systematic and tedious exploration of concepts.

Charles Gorintin, co-founder and CTO of Alan, is a graduate of the Master MVA of ENS Paris-Saclay. Starting from the observation that the healthcare system is not adapted to the reality of its actors (individuals, patients, healthcare professionals), he wanted to make it fairer, more transparent and more personal. With Jean-Charles Samuelian, co-founder and CEO, he created Alan in 2016, a health app that provides access to personalised content, prevention, payment and care services, with access to supplementary health insurance. Convinced that the future of health relies on the best of science and humanities, inspired by Alan Turing, mathematician and father of modern computing, and Alan Watts, American philosopher and humanist, they named their app Alan. A friendly mascot accompanies users every step of the way and is their logo. With 276 employees, Alan has annual recurring revenues of €90 million and expects to grow by 105% by 2020.
