At 21, Mateo Acosta-Rubio has already sold his first company, raised more than $1M for his next and represented the US at the Global Student Entrepreneur Awards Finals.
The work that changed him began with Didi, his fellow Babson classmate from South Sudan. After she passed away, Mateo chose to continue the idea they had started together: LetAllGirls.
Today, the nonprofit is building DIDI, an offline AI tutor that turns a $300 box into a local Wi-Fi hub where students can learn at once, without internet, signal or grid power. DIDI devices are now operating in South Sudan and South Africa.
Born in Venezuela and raised in Miami, Mateo grew up inside his family’s restaurant-franchising business; now a serial founder, he runs Clave, an AI platform for restaurant operations, and can quote the founder podcasts that shaped his thinking almost on command.
Mateo and Vallabhi talk about entrepreneurship as grief, the responsibility of carrying someone else’s vision, the deployment that failed after a year and a half of work, and why meaningful solutions must be built with the communities they serve.
