It's the Data, Stupid
The piece argues that selecting a Demand-Side Platform (DSP) hinges on two factors: unique data and unique inventory. It contends that unique inventory is rare to acquire due to publisher economics and market dynamics, leaving data as the long-term competitive lever unless a DSP gains ownership of inventory through acquisition. The author notes exceptions like The Trade Desk, Beeswax, StackAdapt, Basis, and Simpli.fi, while suggesting that, on margins, buyers prioritize data and inventory. A chart ranks DSPs by Unique Data across players such as Google, The Trade Desk, Walmart, Amazon, Yahoo DSP, Beeswax, Viant, TVision, Iris.tv, MySpace, Basis, Simpli.fi, Adform, Quantcast, Infillion, and Catalina. Caveats include Google's opaque data profile, the murky non-exclusive Walmart-TTD relationship, and Quantcast’s lack of truly unique data. The article highlights two M&A deals: Catalina to Infillion (price undisclosed) and TVision to Viant for about $40 million. It closes with POSSIBLE Miami coverage and an invitation to partner.
