Tom Howard has always been a fan of a good scene. Growing up he was part of the punk and skater crowd in Washington D.C., and today he's still in search for what's hot.

He's part of a community of software developers and entrepreneurs who move from tech hub to tech hub, known to some as digital nomads. He'd spent time in San Francisco and Berlin, before arriving in Vietnam three years ago -- after reading a news article. "It talked about the growing tech scene there, the great lifestyle, the food, the great culture of the people, and I decided to go visit and instantly fell in love with it," Howard told VentureBeat.
