Princeton, NJ-based Invidi, a provider of ad-targeting technology for TV, has taken an unspecified strategic investment from Motorola‘s VC arm. The company has previously raised $53 million, lasting having taken $25 million in a round led by WPP, announced last December. Other backers include Menlo Ventures, InterWest Partners, and EnerTech Capital. Invidi’s technology allows advertisers to target TV viewers based on demographic information and other personal characteristics, and it claims to do so in a way that protects ‘absolute privacy’. Its solution is marketed towards cable and satellite operators and works via set top boxes. The company hasn’t officially announced any cable or satellite customers, although it’s previously said that it’s in talks. Release.
