TST Media, the developer of a Web- and mobile-based software platform for sports venues, has closed on a $6 million round of late-stage VC financing led by El Dorado Ventures. The Minneapolis startup has also rebranded as Sport Ngin. The company, which runs a management platform for professional, amateur and youth sports, will use the funds to accelerate its product development, marketing and sales, as well as for potential acquisitions of complementary technologies. The startup completed a $3.5 million Series B round in August 2011 that put its pre-money valuation at $17.3 million.
