"You can absolutely be what you can't see! That's what innovators and disruptors do," Kimberly Bryant tells me, dismantling the clichéd quote about role models for the underrepresented in STEM (science, technology, engineering, and math). Lack of role models didn't stop Bryant from founding Black Girls Code, a non-profit working on adding a few more shades to Silicon Valley's color palette. The company, founded in 2011, is dedicated to teaching girls K-12 how to code, and has grown to be 6,000 students strong. With chapters in San Francisco, New York, and even Johannesburg, South Africa, Kimberly Bryant is helping give the tech industry a much-needed diversity upgrade.
