In Nigeria, a traditional prosthesis costs about 1.6 million naira, roughly $1,200, and takes four to six weeks to arrive. For many families, that means weeks without work and a debt they cannot carry. Aniefiok set out to shorten the wait and lower the price.
With Taiwo Akinsanya and Kehinde Oluwatobi, she founded Dynalimb. Between them the three founders have more than 25 years of experience in the field. Instead of casting a limb by hand, they scan it digitally and print the socket and device to fit. A patient now waits about seven days. The average device costs around 800,000 naira, about $600.
The company started in a small workshop in Uyo, in Akwa Ibom State, some 550 kilometres from Lagos, where it is now usually said to be based. From there it built a process that begins well before any printing. Staff go into communities to find patients, scan them, produce the device locally, fit it in person and then guide the patient through physiotherapy. A digital platform called DynaX handles remote measurement and follow-up, but trained specialists still carry out every fitting.
The need is far larger than one company. The World Health Organization estimates that only 5 to 15 per cent of people in low- and middle-income countries who need a prosthetic or orthotic device can get one. Across Africa, some 30 million people are thought to need these services.
Dynalimb has grown without venture capital, relying on the founders' own money, grants and startup programmes. It received $10,000 through the Standard Chartered Foundation's Women in Tech Accelerator. In 2025 the Lagos State Science Research and Innovation Council named it one of five Innovation Awardees in a ₦75 million grant round. The founders now plan to expand to Ghana, Kenya and Rwanda.
For Aniefiok, the technology is only a means. Losing a limb, she says, "is not simply about losing a body part." It decides whether a person can keep working, care for their family, take part in society and live independently.
Each of the thousand fittings began with that loss.
