FanDuel co-founder Tom Griffiths just closed a seed round for his decidedly noncontroversial new startup, Hone

Tom Griffiths has founded four companies, two of which "weren't much to write home about," he jokes. The third captured the world's attention: FanDuel, the fantasy sports company that was routinely in the press -- not always for desirable reasons -- from nearly the day it launched, to its near merger with rival DraftKings, to its ultimate sale last May to the European betting giant Paddy Power Betfair in a deal that reportedly saw FanDuel's founders, along with its employees, walk away with almost nothing at the end of their roller coaster ride. Little wonder that Griffith's new, fourth company, Hone, is targeting the comparatively undramatic world of workforce training.
