Boom Entertainment raised $15 million in an initial funding round that included New England Patriots owner Robert Kraft, Golden Nugget Online Gaming, Rush Street Interactive, and former MGM Resorts International chairman Jim Murren.

Formerly known as Boom Sports, the company builds and operates games for an audience of 3 million users. NBC Sports Predictor is its most successful game, but it also works with leagues, sportsbooks, and retailers.

A focus on sports wagering is at the forefront of Boom’s business model, with the new funding helping it “create and change the way sports fans bet.”
