Brussels (Belgium), June 24, 2025 – Axiles Bionics, the deeptech and medtech spin-off from Brubotics at the Vrije Universiteit Brussel (VUB), proudly announces the successful closing of the first €6 million tranche in its €8 million Series A financing round, led and structured by PE Group as cornerstone investor and supported by the EIC Fund and Finance&Invest.brussels, seasoned entrepreneurs, private investors, and the company’s management team2.
The funding will fuel the international commercialization of Lunaris, the most advanced biomimetic prosthetic foot, which blends adaptive mechanics with embedded intelligence to deliver intuitive and natural motion. CE-marked, FDA-cleared, and reimbursed across multiple countries, Lunaris is rapidly gaining adoption in clinical settings. The funding will also accelerate Axiles Bionics’ work on the next generation of bionic devices, currently in advanced development.
Renowned for its groundbreaking innovations, Axiles Bionics has been strongly supported throughout its journey by Innoviris - the Brussels public agency for research and innovation - whose backing has been key to accelerating the company’s pioneering work in advanced prosthetics.
"Axiles Bionics is setting a new benchmark in robotic prosthetics," said Stefan Yee, Founder and CEO of PE Group. "With Lunaris already demonstrating clinical, regulatory and initial commercial success, and a disruptive bionic technology on the horizon, Axiles is well positioned to scale globally and transform the quality of life for amputees worldwide."
Lunaris marks a breakthrough in restoring confident and lifelike movement for lower limb amputees. It is the foundation for new prosthetic technology, offering unmatched biomechanical agility and responsiveness. Clinical adoption is rising sharply, driven by a growing demand from patients and professionals seeking smarter solutions that move beyond traditional prosthetics.
The EIC Fund is proud to participate in this funding round, supporting a European deeptech company that has already demonstrated impressive commercial success and clinical achievements,” said Svetoslava Georgieva, Chair of the European Innovation Council (EIC) Fund Board. She concluded: “Axiles Bionics exemplifies the kind of science-driven innovation Europe needs to stay globally competitive in health technology and human-centric robotics".
Currently in advanced development, Axiles Bionics’ breakthrough bionic technology merges robotics, artificial intelligence, and human biomechanics to unlock a new dimension of movement. By elevating human-machine synergy to unprecedented levels, it promises to transform mobility and significantly enhance quality of life for people with limb loss.
“We envision a future where advanced bionics become standard, enhancing lives with superior mobility, health, and wellbeing. This funding is a vote of confidence in our vision, our team, and the patients we serve,” said Pierre Cherelle, Founder and CEO of Axiles Bionics: “Lunaris has proven that intuitive, lifelike mobility is achievable today. With our pipeline of bionic technologies, we aim to raise the bar once more — and reshape the global standard of prosthetic technology.”
