We began in 2021 as a small, ambitious company making affordable, high-quality reusable pads and fun, educational comic books to help girls learn about periods and their bodies.
Our mission was simple: use profits from pad and comic book sales to provide free menstrual kits and sexual health education to schoolgirls in rural Africa. And we did! Thousands of girls received reusable pad kits (3 pads + 1 wet bag) and our comic books—our way of fighting period poverty.
But we soon realized period products and education weren’t enough. Many girls missed school because of painful periods. Research confirmed it: 3 in 10 girls skip class or struggle to concentrate due to cramps. And 91% of women report period pain, with over half saying it impacts their ability to work. Yet no one was talking about it.
As a social enterprise committed to ending period poverty, we couldn’t ignore this.
So we took action—beyond pads and education—and created Kosi™, a low-cost, drug-free period pain relief device.
Kosi™ is a wearable TENS device that delivers gentle pulses to block pain signals instantly using gate control theory. Just clip it on, press a button, and go about your day, pain-free.
It’s safe, effective, and suitable for all ages. Choose between Kosi™ PRO (sleeker look, longer battery life) and Kosi™ LITE (same power, simpler design). That’s the only difference—well, and the price.
For every Kosi™ sold, we use the profits to help fight period poverty in Africa!
