Prospecting to IT Buyers: How Nine Data Vendors Stack Up

Buyers of information technology (IT) are one of the most valued audiences targeted by business marketers. Globally, these professionals spend $3.6 trillion on hardware, software and technology services. My colleague Bernice Grossman and I recently investigated the availability of prospecting data available to tech marketers for reaching this desirable group, and we found some surprises.

We asked twenty companies who supply prospecting data to business marketers to share with us statistics about the quantity and quality of the data they have on IT buyers in the U.S. Nine vendors graciously participated in our study-specifically,, D&B, Harte-Hanks, Infogroup, Mardev-DM2, NetProspex, Stirista, Worldata and ZoomInfo. Our thanks to them for letting us poke around under their hoods.

We asked each participating vendor to report to us on the number of companies on their databases in ten industries, by SIC code. We also asked for the numbers of contacts with IT titles in a sampling of twenty firms in those SICs, ten large enterprises and ten small businesses. Finally, we sent them the names and addresses of ten actual IT professionals (people whom Bernice and I happen to know, and were able to persuade to let us submit their names), and we asked the vendors to share with us the exact record they have on those individuals. The results of our study can be downloaded here.

This is the same methodology we have used in past studies on prospecting data available to business marketers—although this was the first study we have done on a particular industry vertical. Our objective is, first, to get at the question of coverage, meaning, the extent to which a business marketer can gain access to all the companies and contacts in the target market. And second, we want to show marketers the level of accuracy in the data available for prospecting-for example, is Joe Schmoe still the CIO at Acme Widgets, and can I get his correct phone number and email address?
