Linda Kwamboka, 27, Kenya

Linda Kwamboka co-founded MFarm, which aims to empower farmers, both in Kenya and around the globe.

The company provides farmers with a transparency tool which gives them up-to-date market information, aggregates farmers' needs and orders, and connects them so they can sell collectively.

"If I was giving myself advice five years ago, I would tell myself to focus on my strengths, what is my true talent, and spend enough time to explore what I'm really good at." she says.
