United Internet Media operates as the exclusive ad-sales engine for United Internet AG's portfolio of high-traffic German portals (WEB.DE, GMX, 1&1, mail.com). The tech stack is heavily Microsoft-integrated (Azure, Entra ID, Defender suite) with SAP for enterprise operations and Jira for project management—a pattern typical of large, centralized corporate IT. Active projects reveal a secondary treasury and cash-management focus (digital treasury platform, cash pooling automation, payment optimization), suggesting UIM is consolidating financial operations across the group alongside core ad-sales work.
