In Generation Impact: The Guardians we meet three Costa Rican teens who became friends in high school and bonded over their passion for technology. Together, they are using their talents to help make public spaces safer for women in their country, where six in 10 women say they've experienced sexual harassment—on the street, at work, and in universities. With their startup, Roshe, which includes an app, wearable tech, and a community of women and allies, they're working to make Costa Rica a place where women can move freely and without fear.
