The company operates a managed monetisation platform for web and mobile app publishers. It integrates with publisher properties through a single website tag or an app SDK, enabling server-side header bidding, access to multiple SSPs/demand sources and consent management. The platform provides a dashboard for monitoring performance, testing configurations and controlling ad placements, while the company’s team manages optimisation and support.

Value is created by increasing publishers’ effective ad revenue and simplifying their ad operations, particularly for those without large in-house adops teams. The company aggregates and orchestrates demand from many programmatic partners, manages compliance via CMP integration, and offers a Fixed RPM mechanism to provide revenue stability and forecasting. Operationally it combines proprietary technology with ongoing account management and technical services.

Refinery89 is a Netherlands-based adtech company providing managed web and in‑app monetisation solutions for digital publishers. Its core offerings include a single-tag website integration and a mobile app SDK that connect publisher inventory to multiple programmatic demand sources, server-side header bidding and a consent management platform, with performance visibility through a dashboard.

The company earns revenue by taking a share of advertising income generated via its technology and managed services, including a proprietary Fixed RPM model that stabilises earnings per thousand page views. Its customers are online content publishers and app developers who want to outsource much of the technical and operational complexity of programmatic monetisation while receiving regular payout and account management support.
