Axiles Bionics

What Axiles Bionics does

Axiles Bionics is a Belgian deeptech/medtech company founded in 2019 as a spin-off from BruBotics at the Vrije Universiteit Brussel (VUB), designing and selling biomimetic bionic prosthetic feet for lower-limb amputees. Its flagship Lunaris product line spans three tiers (Essential, IO, and IO+) and combines an anatomical ankle joint with an elastic tendon system that stores and releases energy during gait, embedded sensors, and a 3D-printed TPU foot cover with variable-stiffness zones. The IO and IO+ variants add a smart IoT charger that nightly harvests sensor data to a cloud platform, where deep-learning and reinforcement-learning models refine gait recognition and adapt the prosthesis to individual user biomechanics via overnight parameter updates. The product architecture, underpinned by 17+ years of VUB research and a series-parallel elastic actuation (SPEA) concept, is CE-marked under EU Regulation 2017/745, FDA-cleared, ISO 10328-tested for 2 million load cycles, and reimbursed across several European healthcare systems.

Axiles sells exclusively through certified prosthetists and orthotists (CPOs) under an enterprise field-sales model, with Area Sales Managers being hired across Germany, France, Benelux, and Italy to expand beyond the 2023 launch markets of Belgium, France, Luxembourg, and the Netherlands; certified Canadian CPOs with MDEL licensure can also procure the device. Patient acquisition is supported by an ambassador program with active amputees and an event-driven demand-generation strategy spanning OT World, Health Meets Hardware, Momentum Gathering, and the Belgian Pavilion at Expo 2025 Osaka. The company complements outright purchase with the AxilesCare and AxilesCare+ subscription programs that lower upfront cost through monthly installments and (for IO+) include a lifetime warranty plus continuous software and maintenance updates.

Axiles Bionics has raised approximately €11.4 million cumulatively across a €2.4M initial Series A in 2019, a €0.5M Innoviris Innovative Starters Award in 2021, a €2.5M EIC Accelerator grant in January 2023, and a €6M first tranche of an €8M Series A led by PE Group in June 2025, with the EIC Fund and Finance&Invest.brussels participating. The 15-person organization, more than two-thirds engineers, is led by founder-CEO Pierre Cherelle (PhD in robotics, VUB) alongside co-founder CTO Felipe Gomez, CRO Claire Cherelle, and CFO Jacques Langhendries, with the spin-off relationship with BruBotics/VUB continuing through ongoing clinical trials.

Core offering

Axiles Bionics designs, develops, manufactures, and sells the Lunaris product line of biomimetic prosthetic feet for people with lower-limb amputations. The feet combine robotics, artificial intelligence, and human biomechanics to replicate natural ankle motion, delivered in three tiers (Lunaris Essential, Lunaris IO, Lunaris IO+) along with the IO Charger smart accessory and AxilesCare/AxilesCare+ subscription service plans. The company's value proposition centers on a patented anatomical ankle joint with an elastic tendon system, embedded sensors, deep-learning gait recognition, and CE/FDA regulatory clearances enabling reimbursement in multiple markets.

Product overview

Axiles Bionics offers the Lunaris Product Line of advanced prosthetic feet, consisting of three models: Lunaris Essential (core performance), Lunaris IO (smart connectivity), and Lunaris IO+ (premium with lifetime warranty). The products use biomimetic design inspired by human ankle biomechanics, featuring up to 39° range of motion, 3D-printed TPU foot covers, and adaptive mechanics. The IO and IO+ variants include intelligent connectivity through the IO Charger for data collection and overnight software optimization. Purchase options include traditional buying (with 24-month warranty) or subscription models (AxilesCare/AxilesCare+).
