Jack Eisenberg is the co-founder of Goshi, an iPhone app that creates a mobile marketplace around physical hubs. Jack coded the first version of the app himself (back when it was called MapDing). He and his co-founder Chad still code the app themselves to this day.
Before teaching himself iPhone development, Jack was an ESL teacher and helped people who had never touched a keyboard or mouse before learn to use computers.
