Demand Stream™ includes a Web widget that shows sales and marketing the names of companies visiting the Web site in near real-time. think the idea of an iTunes™ -like interface — and pay-as-you-go pricing structure — for viewing, sorting, and selecting B2B contacts is intriguing. worry that this tool only ends up helping sales pick out cold calls to make, and is not used by marketers enough to segment, collect, and improve their prospecting databases. would put Demandbase here along with firms like Active Conversion, Hubspot, iHance, Leadlander, Sales Genius, and Zoominfo.
