What Protosthetics does

Protosthetics (legal entity Sapiyen LLC, incorporated in Delaware, headquartered in West Fargo/Fargo, North Dakota) designs, manufactures, and distributes custom orthotic and prosthetic (O&P) devices, and operates an FDA-registered facility. The company runs two integrated lines: a Central Fabrication service that produces check sockets, definitive sockets, silicone liners, pectus braces, and rib flare braces using 3D printing and traditional methods, and the Galileo program, a managed in-clinic 3D printing subscription that places 3D printers (HP Multi Jet Fusion, plus FDM/FGF systems from partner Filament Innovations) in O&P clinics and supplies hardware, software, a 7+-year-experienced digital design team, training, ongoing support, and material supply under a monthly fee plus filament costs. The most recent expansion (Galileo O&P, February 2026) extended the program from prosthetics into orthotics, adding AFOs and foot orthotics.

Protosthetics targets US O&P clinics of all sizes, from solo practitioners (e.g., A Leg to Stand On, Family Orthotics and Prosthetics) to multi-location mid-market practices and enterprise accounts (e.g., Methodist Orthotics and Prosthetics), and also serves nonprofit humanitarian missions. The value proposition centers on reducing per-unit fabrication cost by approximately 80% versus external central fabrication, compressing turnaround to same-day or 24-hour, and freeing clinic technicians to focus on higher-value definitive prosthetics. GTM is a hybrid of direct sales outreach to O&P clinics and product-led tactics including free sample check sockets, a public savings calculator, and a custom ordering app (proto.fab.one). Content marketing via a customer-success blog and coverage in O&P trade publications (e.g., O&P Almanac, 3D Printing Industry) drive top-of-funnel awareness.

The company is privately held with no disclosed external funding rounds, leadership consisting of CEO Darren Jacoby, and headcount of 1-10 employees. To date, Protosthetics has printed over 30,000 unique 3D products across the Galileo platform and serves hundreds of US O&P clinicians. Strategic R&D and clinical evidence partnerships (Shabri, October 2022; Filament Innovations, April 2022) underpin product development and validation efforts.

Revenue model

1. Galileo Program Subscription: Monthly subscription model for in-clinic 3D printing program. Includes hardware lease/deployment, digital design services, unlimited customer support, hardware upgrades, and material supply. Customers pay for the monthly subscription plus only the cost of filament/materials used. No upfront capital investment required.
2. Central Fabrication Services: Traditional and 3D printed prosthetic and orthotic products ordered through the Protosthetics app or website. Products include check sockets, definitive sockets, silicone liners, pectus braces, rib flare braces. Fabrication options include both traditional and 3D printed methods with varying turnaround times (3 business days to 2-3 weeks).
3. Galileo O&P Hardware and Materials: Additional revenue from filament/material consumption and potential hardware purchase options. Operating off a monthly design and leasing model removes upfront hardware cost.

Core offering

Protosthetics manufactures and distributes custom orthotic and prosthetic (O&P) devices using 3D printing and CAD/CAM digital manufacturing. It operates two offerings: a Central Fabrication service producing custom prosthetic and orthotic products (sockets, silicone liners, pectus braces, rib flare braces) for clinics, and the Galileo managed in-clinic 3D printing program, which places proprietary printers in O&P clinics under a monthly subscription covering hardware, digital design services, training, materials, and ongoing support.

Product overview

Protosthetics offers two main product lines: Central Fabrication and Galileo. Central Fabrication is an FDA-registered service providing custom orthotic and prosthetic devices through both 3D printing and traditional manufacturing, including silicone liners, check sockets, definitive sockets, pectus braces, and rib flare braces. Galileo is the company's flagship managed in-clinic 3D printing program, combining proprietary hardware, digital design services, material supply, training, and ongoing hardware support under a monthly subscription model. The recently launched Galileo O&P expansion extends orthotic capabilities (AFOs, foot orthotics) alongside existing prosthetic products. Together, these offerings enable O&P clinics to produce custom devices either through central fabrication orders or in-house 3D printing without requiring CAD expertise.
