Business Model Canvas

Completed
Business Model Canvas (9 blocks)

ModuLimb wins if one Egypt-built palm proves bench-safe, then clinics pay for local repairable units.

ModuLimb is a hardware-first prosthetic palm for Egyptian clinics and patients, priced as a one-time sale in EGP with local assembly and imported electronics. I assumed Egypt pricing and a clinic-first entry; the biggest risk is that the cable path and brake jam on the real palm, not in CAD.

Dynamic Model
Customer
The first customer is an Egyptian prosthetic clinic buying a bench-proven palm for patients who need an upper-limb device.
Problem
They need a hand that works locally, is serviceable, and does not depend on expensive imports or long repair delays.
Solution Fit
ModuLimb offers a modular palm with a routed PCB and local assembly, built around the exact cable and brake risks they care about.
Growth
Growth comes from clinic-by-clinic proof, then repeat orders and referrals after each fitted palm performs on the bench.
Sales
Sales start through prosthetist referrals, Benha University demos, and direct founder outreach to Cairo rehab clinics.
Marketing
Bench test logs, open-close videos, and a Benha demo turn a CAD story into proof clinics can trust.
Value Prop
A repairable Egypt-built palm that closes five tendons and can be serviced locally.
Operations
Build the palm in Cairo, route the R04 PCB, then cycle-test each unit before clinic handoff.
Talent
You need a prosthetist, a mechanical builder, and a PCB/layout person who can catch the 25.2 V edge case.
Pricing Payment
Sell one palm for EGP 18,500, paid by bank transfer or Fawry before build.
Revenue
Revenue comes from one-time palm sales and small pilot batches to clinics.
Costs
The biggest costs are the EGP 78,000 prototype, EGP 15,940 PCB checkout, and local machining.
Margins
Prototype margins are negative; the lever is cutting the unit toward EGP 4,500 at pilot scale.
Cash Flow
Cash is tight because build costs land before clinic payment, so deposits matter.

Hardware Path

Completed
Hardware path

ModuLimb can reach a 100-unit pilot with a bench-valid palm, then scale only after cable-path, brake, and power safety are proven.

Build a local-first prototype in Egypt using off-the-shelf motion parts, 3D-printed or CNC enclosure pieces, and imported PCB assembly only if needed. Assume Egypt pricing with USD converted at EGP 50 per USD; the biggest cash risk is the first reliable palm mechanism, because cable friction and brake design can kill the project before pilot.

Key Risk
The biggest risk is the real cable path and brake behavior failing under load, because the palm may work in CAD but jam or slip on the bench.
Next 30 Days

1) Build one palm test rig and measure tendon stroke, friction, and return force; 2) order one PCB spin from JLCPCB and one local mechanical shell; 3) run 20 open-close cycles and log current, heat, and stall behavior; 4) quote a Cairo contract assembler and a local machine shop; 5) book one prosthetist or rehab engineer review and record the changes.
