GAIN

GAIN (operating under thisisgain.com, formerly operating within the Sideshow Group network) is a multi-national, creative-led digital experience and performance marketing agency. Grounded in a philosophy they call "Rebel Thinking," GAIN blends deep data analytics, predictive conversion optimization, and brand design to accelerate digital growth for global enterprises like Loop Earplugs. The agency functions as a unified collection of six core specialization units—covering GAIN Experience, GAIN Conversion (recognized as one of the world's largest dedicated digital experimentation agencies), GAIN Performance, and specialized teams in Customer Science, Creative Studios, and Social/Influencer strategy. By synchronizing technical SEO architecture, server-side A/B testing, machine learning consumer insights, and cross-channel paid acquisition pipelines, GAIN removes operational silos to deliver measurable multi-million dollar revenue uplifts for international clients. Operating out of its global headquarters in London alongside regional hubs in North America, Spain, India, and the Philippines, the firm scales cross-border creative and data tech capabilities on a global scale.
