Mattermark
Mattermark's Overview
Mattermark was a prominent data intelligence platform offering insights into private and public companies, widely used by venture capital firms, sales professionals, and marketers. It provided extensive data on company funding, employee growth, web traffic, mobile app data, and other key business signals to facilitate company discovery, research, and lead generation. Founded in 2012, Mattermark quickly became a go-to resource for understanding the startup ecosystem. In December 2017, Mattermark's assets were acquired by FullContact, a company specializing in contact management and identity resolution services. While the standalone Mattermark platform as originally conceived has since evolved as part of FullContact's offerings, its legacy lies in providing rich, actionable company intelligence.
