## About

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.

## Questions

### How does Müller Media & Service's dual mandate work?

The firm operates simultaneously as an in-house media agency and a single-family office. It optimizes media planning, buying, and agency management for Unternehmensgruppe Theo Müller's consumer brands across Europe, while separately managing the family's investment portfolio across private equity, real estate, and public markets. Both functions are run from the same Zurich office by the Managing Directors.

### What is the relationship between Müller Media & Service and the Theo Müller Group?

Müller Media & Service is a wholly owned service entity of Unternehmensgruppe Theo Müller S.e.c.s., the Luxembourg-headquartered holding company for the Müller dairy and food products empire. The firm shares a Zurich address with another group entity, Müller Einkauf & Service AG, reflecting a cluster of centralized service functions for the group.

### Does Müller Media & Service manage money for external clients?

No. The firm is a single-family office dedicated to the founding family of the Theo Müller Group. Its media agency services are also captive, serving only the group's own consumer brands rather than external advertisers.

### What investment stages does Müller Media & Service target?

Publicly confirmed investment activity spans direct private equity and real estate ownership. The firm does not disclose specific stage preferences, but its capital-preservation mandate and alignment with a mature operating business suggest a preference for later-stage, asset-backed, or income-producing investments rather than venture capital.

### Which geographic regions does Müller Media & Service invest in?

The firm's confirmed investment focus is Europe. This includes real estate holdings in the Netherlands, and its media operations span multiple European markets where the Müller group's consumer brands are active.
