Mid-tier attribution platform focused on cross-channel measurement before acquisition by Neustar
C3 Metrics was a marketing attribution technology company that provided cross-channel attribution and analytics solutions to help advertisers understand the customer journey across multiple touchpoints. The company specialized in unified marketing measurement, offering tools that enabled marketers to attribute conversions accurately across digital and offline channels, optimize media spend, and improve ROI. C3 Metrics differentiated itself through its focus on person-level attribution and its ability to integrate data from various marketing channels including display, search, social, email, and offline media. Founded in 2008, C3 Metrics served enterprise brands and agencies seeking sophisticated attribution modeling capabilities beyond last-click attribution. The platform provided insights into how different marketing channels worked together to drive conversions, allowing marketers to make data-driven budget allocation decisions. In 2017, C3 Metrics was acquired by Neustar (now part of TransUnion), a provider of identity resolution and marketing analytics solutions. Following the acquisition, C3 Metrics' technology and capabilities were integrated into Neustar's MarketShare attribution platform, and the C3 Metrics brand was eventually phased out as its functionality became part of the broader Neustar marketing analytics suite.
