Ed.ai Raises 5 Million Euros to Accelerate the Rollout of Its AI Assistant Designed to Promote Educational Success
Supported by 21st by CentraleSupélec since 2024 and co-financed by CentraleSupélec Venture, the startup Ed.ai has reached a new milestone with a €5 million funding round. This growth illustrates the momentum of CentraleSupélec’s entrepreneurial ecosystem.
How can we give teachers more time to support their students, identify their difficulties, and implement appropriate remedial measures? This is the challenge addressed by Ed.ai, an EdTech startup founded in 2024 by Jonathan Banon, Cédric Bignon (both CentraleSupélec alumni), and Rémi Mazières.
Its goal: to turn every test into a genuine tool for progress by putting artificial intelligence to work for teachers and the success of every student.
From Grading Papers to Educational Remediation
Grading exams takes up a significant portion of teachers’ time. Yet, beyond the grade itself, each exam contains valuable information about students’ learning, mistakes, and the challenges they face.
“There’s an untapped but exploitable treasure: students’ exams,” observes Jonathan Banon.
Ed.ai is developing an AI-powered teaching assistant to support teachers in this process. The solution helps speed up grading, provide detailed feedback, and identify students’ strengths and weaknesses.
Based on this information, Ed.ai then generates personalized remedial activities tailored to the specific mistakes actually observed.
“Our goal is for every student to receive tailored support, without adding to the teacher’s workload.”
Ed.ai: A Journey Supported by the CentraleSupélec Ecosystem
Founded by Jonathan Banon and Cédric Bignon, Ed.ai benefits from the School’s entrepreneurial ecosystem, notably through support from 21st by CentraleSupélec starting in late 2024.
In April 2025, Ed.ai announced its first funding round of 1.7 million euros, raised primarily from CentraleSupélec Venture, the school’s alumni fund. This initial funding was intended to accelerate the rollout of its AI assistant to teachers.
Since then, the startup’s growth has accelerated significantly.
A New €5 Million Funding Round
Ed.ai announced today a new €5 million funding round, intended to accelerate its development in France and prepare for its expansion into the U.S. market.
In just one year, the startup has gone from grading 100 tests per week to 2,500 tests per day. It is now deployed in 500 schools across France, and its solution is available in all 50 U.S. states, in middle and high schools.
Tens of thousands of students are expected to use the platform by the start of the 2026 school year. To support this expansion, Ed.ai has begun recruiting its first U.S. employees and is leveraging a local network of teacher-authors.
The startup also plans to expand its solution to new subjects and launch pilot programs in U.S. higher education.
A goal: putting AI to work for educational success
The AI developed by Ed.ai is not intended to replace teachers, but rather to enhance their analytical capabilities and save them time.
Augmented grading, learning analytics, identification of difficulties, and generation of remedial activities: the technology is designed as an assistant that enables teachers to better leverage the information contained in each student’s work.
Ed.ai thus advocates an approach in which technology supports pedagogical expertise and facilitates more individualized support.
A trajectory that illustrates the strength of the CentraleSupélec ecosystem
Ed.ai’s growth exemplifies CentraleSupélec’s entrepreneurial spirit: empowering the School’s talented students to transform their ideas and expertise into projects capable of growing and scaling up.
Since its inception, Ed.ai has benefited from this continuity: two of its co-founders are CentraleSupélec alumni, the startup has been supported by 21st by CentraleSupélec since 2024, and CentraleSupélec Venture participated in its first funding round.
Beyond these initiatives, this trajectory demonstrates how the ecosystem’s various resources—support, funding, networking, and the alumni community—complement one another to foster the emergence and growth of high-impact technology projects.
This latest funding round thus marks a new milestone for Ed.ai, which intends to accelerate its growth in France and continue its expansion in the United States.
CentraleSupélec extends its congratulations to the entire Ed.ai team—and especially to its co-founders Jonathan Banon, Cédric Bignon, and Rémi Mazières—on this new milestone.
