What MUM does

MUM S.A. is a privately held, full-service digital marketing and communications agency headquartered in Weiswampach, Luxembourg. Founded in 2000, the company operates with an in-house team of approximately 10 experts and serves small and medium-sized enterprises (SMEs) as well as institutional clients across Luxembourg, Belgium, and the Greater Region. Its core proposition is end-to-end digital marketing — strategy, creation, marketing campaign execution, and web application development — delivered either à la carte or as a full-service partnership, with native multi-language capabilities (French, German, Luxembourgish).

The technology backbone consists of two proprietary assets: WebCore CMS, a SaaS content management system developed in-house over 15+ years and deployed across 500+ projects with a lifetime guarantee and continuous updates, and MailCore, a proprietary email marketing platform with CRM/ERP/database integrations. These are complemented by a Microsoft Azure-hosted infrastructure, Microsoft 365 cloud services delivery, and Web Applications built on .NET/PHP and SQL/MySQL. In September 2025, the agency launched KI-Tools & KI-Lösungen (AI Tools & Solutions), offering generative AI content, AI chatbots for customer service, and sales automation built on third-party foundation models (ChatGPT, Claude, Google Gemini).

MUM generates revenue primarily through project-based fees and ongoing retainer arrangements, with website packages tiered from <€2,500 (Compact) to >€7,500 (High-end), full-service engagements typically ranging €3,000–€25,000, and additional revenue from WebCore SaaS subscriptions and Microsoft 365 cloud services. The company is a certified Google Partner, Meta Business Partner, and LinkedIn partner, and is an approved provider for Luxembourg's SME Package Digital government subsidy program since 2020, having processed 40+ client dossiers. The firm is bootstrapped, independently owned, and self-sustaining with no disclosed external investment.
