Problem
Brands and agencies must manually coordinate with multiple advertising platforms, each with its own rules, pricing, and compliance requirements, making cross‑channel campaign planning slow, error‑prone, and costly. The lack of a unified, auditable transaction layer limits transparency, governance, and the ability to scale media buying across emerging surfaces such as AI assistants, CTV, audio, and out‑of‑home.
Solution
Scope3 provides the Interchange, an open‑protocol infrastructure (AdCP) that enables AI agents representing brands (buying agents) and surface owners or service providers (sales agents) to discover, negotiate, and transact advertising inventory across any media surface. Brands encode their objectives, budgets, and governance rules into a buying agent, which then autonomously evaluates storefront catalogs, selects optimal placements, and executes purchases while enforcing brand standards and compliance. All interactions are recorded on the Interchange, delivering full auditability, transparent pricing, and real‑time reporting. The platform supports both simple routing (4 % margin) and decisioned transactions with optimization (8 % margin), allowing clients to choose the level of automation they need. By standardizing agent‑to‑agent communication, Scope3 removes the need for bespoke integrations, accelerates campaign launch, and scales media buying to both established and emerging channels.
