This 20-yr old Harvard dropout built the next Facebook in Zuck’s old room

Harvard dropout → AI founder. Meet Sungjoo Yoon, CEO of Biography, a “relational intelligence” startup on a mission to make the internet warmer, more intimate, and more human. Before building Biography from Kendall Square, Sungjoo jolted campuses nationwide by spotlighting major data security gaps in Datamatch, a popular college matchmaking app—raising hard questions about how casually we surrender personal data. Today, Sungjoo is building his company, filled with the smartest people he knows, in a way that is ethical and keeps data privacy at the forefront of its mission.
