Scope3

Scope3 is an agentic advertising platform that enables brands, agencies, publishers, and SSPs to activate more effective, safe, and sustainable media campaigns. Co-founded in 2022 by Brian O'Kelley and Anne Coghlan — original architects of programmatic advertising — Scope3 built a collaborative emissions measurement model adopted by leading brands including Google, Meta, Coca-Cola, and GroupM. The platform provides brand agents powered by LLMs that manage brand presence across media, nuanced content suitability controls, and transparent media measurement. Scope3 has contributed its core carbon modeling methodology to open source and invested $1MM in carbon removal with Carbon Direct.
