Vindico, a video ad management platform, on Tuesday announced the launch of a demand-side platform (DSP). The new DSP, dubbed Vindico Bid Manager, puts a focus on quality inventory. Vindico says the DSP uses Adtricity -- Vindico’s media measurement tech -- to rank and rate all of the inventory it sees based on viewability and ad quality. The Adtricity tech grades the performance of inventory from A through F.The purpose of the new platform is to give the buy-side “additional transparency and control,” starting with knowing the quality of the ads they are buying. Vindico also claims the DSP has “real-time blocking capabilities” so buyers can avoid purchasing low-grade inventory even in a programmatic environment. Vindico has partnered with some of the largest programmatic video inventory providers to launch its new DSP, including Adap.tv, AppNexus, LiveRail and SpotXchange.
