Mediani

Mediani Group Oy is a Finnish adtech company that provides a B2B advertising sales and inventory marketplace for media owners, advertisers and media agencies. Its core product combines advertising inventory discovery, campaign planning, order management, booking and self-service sales workflows. The platform is designed to help publishers and media companies manage direct ad sales more efficiently while giving buyers a faster route to find and purchase relevant advertising placements across multiple channels. The company generates revenue through a mixed software and transaction model. It sells platform access and operational tooling to media companies, and it also monetises marketplace activity tied to advertising transactions processed through the platform. Its direct customers are businesses rather than consumers: publishers and media owners on the supply side, and advertisers and agencies on the demand side.
