Founded in 2015 and operating as a wholly-owned subsidiary of WPP, the firm serves global consumer brands, CPG/FMCG companies, financial services firms, media owners, retailers, and emerging verticals such as sports betting and gaming. Named clients include Diageo, Danone North America, Nomad Foods, NBCUniversal, NatWest Group, HSBC Life, BetMGM, and Aviva.
The company's core technology stack centers on HiFusion, an AI-driven marketing effectiveness platform that combines marketing mix modeling (MMM) with scenario planning, creative effectiveness measurement, and organizational readiness diagnostics.

The firm was named a Leader in The Forrester Wave: Marketing Measurement and Optimization Services, Q1 2026, with the highest possible strategy score.
Gain Theory operates a B2B professional services model combining project-based consulting engagements with recurring analytics-as-a-service subscriptions, including annual MMM programs and ongoing measurement work. Go-to-market is direct enterprise sales supported by thought leadership content, industry conference participation, co-published research with WARC, and WPP network relationships.
