ProspectOne provides a comprehensive suite of B2B data products that deliver accurate, actionable prospect data for all your sales and marketing needs. ProspectOne was launched to answer a very specific need. As long-time leaders in technology-enabled, data-driven marketing, the founders were intimately familiar with the immense business value of accurate and complete prospect data. Their idea was to vastly improve the quality of B2B contact records by combining their proprietary intelligence platform with a rigorous hand-verification and QA process. The result of this powerful combination of technology and human insight is the flexible ProspectOne data-on-demand product that provides on-demand data through a self-serve interface, hyper-specific and custom list building through ResearchOne, and a broad and versatile verification and QA service through QualityOne
