Masher Media, which is developing a virtual world for kids aged 6 to 13, has raised $300,000 of a $1 million round, according to an SEC filing. The startup raised the funds from California angel investor network Tech Coast Angels, according to CEO Sherry Gunther. Gunther is a former TV producer who has won Emmies for her work on Rugrats and the Simpsons. Masher’s game, MyMiniPeeps, will be Gunther’s second. She previously launched ZooKazoo.com. The new game is expected to debut in fall 2010.
