Abstract This contribution examines Heike Schweitzer’s role as a competition policy analyst and adviser in the formative phase of European competition policy towards digital platforms. It situates her work in this context and develops a conceptual framework that captures the challenges of analysis under conditions of uncertainty and dynamic market developments. Through a selective analysis of four key reports, the article reconstructs central analytical approaches and policy proposals, identifies characteristic features of a “Heike Schweitzer approach”, and assesses its influence on subsequent regulatory developments, in particular the Digital Markets Act and section 19a of the German Competition Act.
