Our Story

Next generation B2B data solutions for sales and marketing teams

At RevenueBase, we believe that data is at the heart of great sales and marketing strategies. But, over the last decade, very little has changed to improve how organizations acquire and manage their B2B data for sales & marketing. First-generation list vendors cannot adequately address modern marketers’ needs, resulting in a “spray and pray” approach that doesn’t work.

Leveraging modern technology, and generative AI, we built the first-ever B2B Revenue Database as a Service solution. This one-stop solution offers business leaders more and better data that can quickly be converted into revenue growth. We strive to deeply understand our customer’s go-to-market opportunities and deliver the definitive account and contact information through an easy-to-manage and updated database.

RevenueBase works with B2B growth organizations of all sizes—from the Fortune 500 to seed-stage startups. Headquartered in Boston, Massachusetts, we have a global team ready to support our client’s needs.
