Metric Theory

Was a well-regarded independent performance marketing agency in the U.S. mid-market space before being acquired and rebranded under Wpromote in 2021.

Metric Theory was a San Francisco-based independent performance marketing agency that built a strong reputation for data-driven paid media management across search (Google, Bing), paid social (Facebook, Instagram, LinkedIn), and programmatic channels. Founded in 2012, the agency distinguished itself through a rigorous analytical approach to campaign optimization, serving mid-market and enterprise brands across e-commerce, B2B, and consumer verticals. Metric Theory grew to become one of the more recognized independent performance agencies in the United States, earning recognition on lists such as Inc. 5000 and winning multiple industry awards for campaign performance and workplace culture. In 2021, Metric Theory was acquired by Wpromote, a larger independent digital marketing agency. Following the acquisition, Metric Theory's operations, team, and client relationships were integrated into Wpromote, and the Metric Theory brand was effectively sunset as the combined entity operated under the Wpromote name. The merger significantly expanded Wpromote's headcount, geographic footprint, and capabilities in performance media. During its independent operation, Metric Theory served hundreds of clients ranging from venture-backed startups to established mid-market and enterprise companies. Its value proposition centered on transparent, performance-focused paid media management with dedicated account teams and proprietary optimization processes. The agency's absorption into Wpromote marked the end of the Metric Theory brand as a distinct entity in the AdTech and agency ecosystem.
