Kwarter, a San Francisco-based developer of TV viewer communities for broadcasters, content producers and brands, said on Tuesday it has raised $4 million in first round of funding, led by T-Venture. Kinetic Ventures also participated in the round, which brings Kwarter’s total backing to $5 million since its founding in 2011.
