Industries and governments are marching on towards digitizing our lives, for better or worse. Nithya, co-founder and CEO of Nexleaf, is one of the people working to bring powerful data insights and deep engineering expertise to ensure data is actually used with equity in mind and with real impact. Nexleaf’s temperature-sensing technology is just one example, helping millions of kids around the world get the vaccines they need. Other key lessons: thinking about impact in terms of incentives and disincentives; striving for equity and social value, rather than behavior change.
