Rezolve Medical

What Rezolve Medical does

Rezolve Medical (legal entity Rezolve B.V.) is an Amsterdam-based medtech company that designs, manufactures, and distributes "The Rise," a fully personalized 3D-printed ankle-foot orthosis (AFO) for adult ambulatory patients with drop foot caused by dorsiflexor weakness. The device is engineered from a 3D scan of the patient's leg and foot, produced in orthopaedic nylon polymer, and incorporates a proprietary custom compliant hinge with tunable stiffness and pre-load that stabilizes the ankle at heel strike and ensures toe clearance during swing phase. The Rise is offered in two support levels — Level 100 for patients with dorsiflexor strength of MRC grade 3-4, and Level 110 for MRC grade below 3 — weighs under 200 grams, sits on top of the foot rather than underneath, and is designed to integrate with lace-up footwear. Indications span multiple sclerosis, stroke, Charcot-Marie-Tooth, peroneal nerve injury, peripheral nerve damage, incomplete spinal cord injury with foot drop, and traumatic brain injury with foot drop.

The company's go-to-market is sales-led and clinician-mediated. Rezolve sells through onboarded orthotic clinic partners using a structured three-step onboarding process (initial contact, commercial meeting, on-site technical meeting), with named channel partners including Leuk Orthopedie in the Netherlands and Vigo Wetteren in Belgium. Patients require a prescription from a rehabilitation doctor or orthotist, after which a 3D scan is taken and the device is delivered to the clinician in approximately two weeks. In the Netherlands, The Rise is covered under basic reimbursed healthcare, providing a defined payer pathway. The company also operates the "AFO Experience," a free trial session enabling prospective patients to compare The Rise with competing foot-lifting aids under clinician supervision.

Rezolve Medical is privately held, founded in 2023 by Lennart Zielstra — himself a drop foot patient following a 2014 accident — with biomedical engineering credentials from TU Delft. The team of approximately six people includes co-founder and COO Joris Zielstra (joined full-time March 2025 from a Big Four legal/advisory background), a Clinical Engineer, an Orthotic Engineer and MDR Compliance Consultant, a Service Designer, and an MSc intern. Clinical validation has been conducted at Amsterdam UMC under METC approval, and the company maintains development relationships with TU Delft, Be-On Quality, EPC, PIB, and PNH. No external funding rounds, revenue figures, or institutional investors are disclosed in the available source material.

Broad incumbents

• Össur: Icelandic-headquartered orthopedics company with strong AFO and bracing offerings serving similar patient populations (drop foot, neurological indications). Larger incumbent with global distribution.
• Fillauer: US-based manufacturer of orthotic and prosthetic components and devices, including dynamic AFOs. Overlapping customer base of orthotists and orthotic clinics.
• Ottobock: Global leader in prosthetics and orthotics with a broad portfolio including ankle-foot orthoses. Highly comparable category but at vastly larger scale and broader portfolio than Rezolve's single-product focus.
• Fior & Gentz: German manufacturer specializing in orthotic components and joint systems for lower extremity orthoses. Comparable technology and prescriber base, though component-focused rather than full-device.

Direct peers

• SURestep: Manufacturer of dynamic AFO products (originally pediatric, now broader) targeting similar drop-foot and gait-disorder indications. Comparable patient population and prescriber base.
• Trulife: Orthotic manufacturer with AFO products for drop foot and related gait disorders. Comparable device category with similar clinical positioning.
• Allard Support: Swedish manufacturer known for dynamic AFOs (ToeOFF, blueROCKER) targeting drop foot. Most directly comparable product category and patient indication, with similar emphasis on natural gait restoration.

Regional players

• Basko Healthcare: Dutch/European orthopedic device manufacturer and distributor with AFO and orthotic offerings. Comparable product category with overlap in the Dutch/Benelux market where Rezolve currently operates.

Emerging players

• Xkelet: Spanish startup developing 3D-printed personalized orthotic devices. Comparable emerging-stage competitor using additive manufacturing and digital scanning for custom orthotics.
• Andiamo Health: UK-based startup applying 3D printing to custom orthotics for children with disabilities. Comparable 3D-printed personalization approach and adjacent patient population, though pediatric-focused.
