Founded: 2011
Valuation: $1.2 billion
DraftKings is a $1.2 billion daily-fantasy-sports site that lets its users bet real money on their teams. You may have seen its ubiquitous TV advertisements telling you about how some of its members have cashed out crazy sums of money using DraftKings.
The startup is also mired in controversy: Earlier this year, The New York Times reported that a DraftKings employee admitted to "inadvertently releasing data before the start of the third week of N.F.L. games." That same week, the employee won $350,000 at FanDuel, DraftKings' biggest competitor in the daily-fantasy-sports business.
DraftKings, Boston-based startup, has raised $375 million in venture capital funding from investors like MLB's venture arm, Melo7 Tech partners, the NHL, and Redpoint Ventures.
