New York startup Umami said in a press release Tuesday it raised $1.65 million in seed funding from Battery Ventures, NEA, and angel investors. Umami is a platform that broadcasters can use to publish additional content for television shows that viewers are watching. Umami said it has a free iPad app currently in a closed beta test with undisclosed television networks and others. Umami was founded by Scott Rosenberg, most recently vice president of advanced advertising at Rovi, and Bryan Slavin, former vice president of product development at Lightningcast. Umami plans to launch its services with this year’s fall television season.
