Video game streaming startup Rainway is raising more cash and bolstering its advisory board. The Seattle company just reeled in another $3.5 million, adding to its seed round from last year. Investors include Bullpen Capital (which led the latest round); Madrona Venture Group; GoAhead Ventures; and Bill Mooney. Total funding to date is $5.2 million. It also recently brought on David Perry, former CEO of game streaming company Gaikai (acquired by Sony for $380 million) and Jon Kimmich, a longtime Microsoft leader who helped launch the original Xbox.
