About LoopMe:

LoopMe is an AI company dedicated to solving the challenge of making brand advertising measurable and performant. Our platform utilizes patented machine learning models across billions of consumer signals in real-time, optimizing campaigns towards outcomes like purchase intent and brand lift, rather than proxy metrics like clicks. This results in 2-5x better performance than industry benchmarks at scale. We operate a high-load programmatic infrastructure, processing millions of ad requests per second with sub-200ms response times globally. Founded in 2012 and headquartered in London, LoopMe has over 400 employees across 19 cities and has sustained 40% revenue CAGR since 2018.
