Co-Founder

Nuway

Boston/Uganda

nuway (formerly Nyweza) is a startup making boda bodas (motorcycle taxis) safer in Uganda. I was a co-founder of the company, which was formed after winning a pitch competition at MIT in April 2015. During my time at the company, we took an idea for a safety device from a brainstormed concept to a first generation product that is being field tested in Uganda. My role at the company was fundraising, and I was able to secure enough capital for initial product development and testing. I am no longer at the company due to my commitments in the states.During my tenure at nuway, I gained many practical skills that come with attempting a startup, including public speaking, developing a business plan, and effectively pitching an idea. I was fortunate to participate in accelerator programs from Unreasonable and Social Enterprise Greenhouse. I was also able to share our story at conferences, pitch competitions, and other events around the country.
