C3 Metrics

Premium enterprise multi-touch attribution vendor with differentiated TV attribution capabilities, acquired by FreeWheel (Comcast) in 2021

C3 Metrics was an enterprise-grade multi-touch attribution (MTA) and marketing measurement platform founded to solve one of advertising's most persistent challenges: accurately crediting each touchpoint in a consumer's path to conversion. The company developed a proprietary Attribution Data Cloud that ingested impression-level data across display, video, search, social, and TV channels, enabling marketers to move beyond last-click attribution and understand the true contribution of each ad exposure to business outcomes. The platform was particularly notable for its work in TV attribution, offering one of the earlier solutions that could connect linear television advertising to digital conversions — a capability that set it apart from many digital-only attribution vendors. C3 Metrics served large enterprise clients including major financial services firms, retailers, and CPG brands, positioning itself as a premium solution for sophisticated marketing organizations with complex, multi-channel media investments. C3 Metrics was acquired by Comcast's FreeWheel in 2021, reflecting the growing strategic importance of cross-channel attribution — especially as connected TV and streaming advertising accelerated. Following the acquisition, C3 Metrics' technology and team were absorbed into FreeWheel's broader advertising technology ecosystem, and the C3 Metrics brand was effectively sunset as a standalone entity. Its legacy lies in pioneering impression-level MTA and helping establish TV attribution as a credible, data-driven discipline.
