Engineering prosthetics that work for a lifetime.
A research-driven team building modular, affordable, and accessible prosthetic mobility technologies.
A critical gap in prosthetic access
Millions face mobility challenges due to lower-limb amputations. While technology has advanced, critical gaps remain:
- High costs make prosthetics inaccessible to most who need them.
- Fixed designs limit long-term comfort as users' needs change.
- Repairs are expensive or unavailable, leaving users stranded.
- Terrain adaptation is poor — conventional feet struggle on slopes and uneven surfaces.
Advanced assistive mobility, accessible to everyone
We believe assistive mobility should be both advanced and accessible. Our mission is to improve everyday movement for people with lower-limb amputations through practical, affordable engineering.
Prosthetics that adapt, repair, and serve for life
A future where prosthetic devices are modular, serviceable, and built to last — growing with their users rather than requiring complete replacement.
Transtibial Systems
Exclusive focus on below-knee prosthetic design — the most common amputation level.
Detachable Ankle
Modular ankle module enabling adjustment, repair, and replacement without replacing the full device.
Passive Foot
Practical, serviceable foot solutions for daily use across varied terrain and activity levels.
Architecture & Design
A purely mechanical modular ankle system
Our patent-pending ankle attachment represents a fundamental shift from monolithic designs toward truly modular prosthetic architecture.
It integrates between the prosthetic foot and the rest of the assembly, enabling controlled ankle articulation while maintaining structural stability.
Mechanical Intelligence
No batteries, no electronics — a purely mechanical system designed for maximum durability and minimal maintenance in low-resource environments.
Controlled Articulation
The ankle joint enables controlled movement during walking while maintaining the structural stability required for safe daily use.
Slope-Adaptive Future
Long-term goal: ankle mechanisms that accommodate incline and decline walking on varied terrain conditions.
Development Milestones
Prototype Refinement & Lab Validation
Refining the mechanical prototype and completing laboratory validation for reliability and consistent performance.
User Testing & Clinical Feedback
Conduct user testing with transtibial prosthetic users through prosthetic clinics and rehabilitation organizations.
Early Market Entry & Product Expansion
Begin early market entry through partnerships with prosthetic service providers and expand the modular technology platform.
A growing global need
The global prosthetics and orthotics market is growing steadily, driven by rising cases of diabetes, vascular disease, trauma-related amputations, and aging populations.
Billion Health aims to address this market by focusing on modular, accessible prosthetic innovations built for everyday environments — not just laboratory conditions.
