Problem
Publishers, SSPs, DSPs, and agencies rely on third‑party services to capture, resolve, and activate first‑party signals, incurring onboarding fees and losing control over data ownership and quality. This limits revenue potential and hampers performance in automated, AI‑driven media buying.
Solution
GrowthCode offers an independent signal infrastructure that enables each participant in the advertising supply chain to capture first‑party identifiers directly on publisher pages, resolve them into a deterministic identity graph, and activate the signals across display, mobile, and CTV. The platform provides a single on‑page script that collects hashed emails, mobile advertising IDs, IP‑derived IDs, and contextual data with sub‑10 ms latency, then structures the data into a persistent, privacy‑first signal spine owned by the client. By minting proprietary IDs at the source and mapping existing buyer IDs to preferred EID formats, GrowthCode eliminates third‑party onboarding fees and ensures every bid request carries a usable identifier. The infrastructure is built for machine‑speed buyer‑side AI, delivering complete, consistent signals that improve match rates, CPMs (20 %+ uplift for hashed‑email coverage), and overall yield. Clients retain full control over data storage, retention, and activation, with analytics that surface signal quality, mint and match rates, and revenue contribution.

Primary customers are publishers, supply‑side platforms, demand‑side platforms, and media agencies that need to capture, own, and monetize first‑party data across programmatic channels.
