Müller Media & Service

Müller Media & Service

Müller Media & Service operates as the in-house media agency and single-family office for the Unternehmensgruppe Theo Müller, the dairy conglomerate behind brands such as Müller, Weihenstephan, and Homann. Headquartered in Zurich, the firm was established to centralize media planning, buying, and controlling for the group's consumer goods portfolio, while simultaneously stewarding the founding family's diversified financial assets. Beyond its operational media mandate, the firm deploys capital across private equity and real estate, with a confirmed geographic focus on Europe. The real assets footprint includes an office property in the Netherlands under the Almhof brand. While specific portfolio company names remain private, the investment posture balances direct holdings with a capital preservation ethos tied to the broader Müller group's long-term legacy. The Zurich-based team is led by Managing Directors Stefan Burgaß, who previously served on the board of the Organisation Werbungtreibende im Markenverband, and Tobias Tarlosy, who spearheaded a landmark collaboration with INSEAD announced in January 2025. The firm also maintains ties to professional networks including Arbeitgeber Zürich and the Marketing Club Frankfurt. Müller Media & Service's architecture is unusual: it combines a fully operational media agency serving a single corporate parent with the discretionary investment function of a family office. This dual mandate means the same Zurich team manages both the annual advertising spend for consumer brands across Europe and the long-term allocation of the family's private wealth — a structure that embeds investment decisions within the operating rhythms of the group's core business.
