Umami, a New York technology firm, has signed up National Geographic Channel as one of the first networks to use its TV companion product for iPads.
Umami's app, which will be available at the Apple App Store Tuesday, uses audio fingerprinting technology to sync continuously and automatically with live or time-shifted programming from all major broadcast and cable networks, giving viewers access to related content and social media activity.
A number of other partners will go live in the coming weeks, providing viewers with deeper content across a variety of programming, Umami said.
Umami was co-founded by CTO Bryan Slavin, who'd previously worked at Lightningcast, Leap Wireless and Broadsoft, and Scott Rosenberg, who has been with Intel, ReplayTV, BlackArrow and Rovi. In August, Umami announced $1.65 million in seed funding from backers including NEA and Battery Ventures.
