Bloc was founded in February 2012 by Roshan Choxi and Dave Paola.
They met at the University of Illinois at Urbana-Champaign in 2008, before moving to San Francisco where the company is currently headquartered.
Subsequently, Paola and Choxi began tutoring students over Skype in 2012, then later introduced Bloc at the Launch Festival in San Francisco.

Officials at Thinkful said Bloc was not profitable and "almost breaking even" at the time the deal closed.
