## About

Kotte & Cie operates as a corporate multi-family office anchored in northwestern Germany, managing administrative and strategic oversight for multiple high-net-worth families. Andrea Kotte leads the firm day-to-day, while Managing Director Sebastian Kotte concurrently serves on the board of Spiekermann & CO AG, an Osnabrück-based asset manager, creating a two-way pipeline for investment execution and client referrals. The firm does not disclose the wealth origin of its founding or client families, but public corporate records tie the Kotte leadership to joint real-estate ownership vehicles with Hans-Heiner Müller, founder of WM SE, through entities such as Gemelo Real Estate GG 58 GmbH and HDM Grundstücksgesellschaft mbH. The firm presents itself as a central hub for family wealth, coordinating across banks, insurers, and tax advisors. Its stated services cover four pillars: consolidated wealth reporting, succession and intergenerational transfer, investment optimization, and full administrative management. The investment approach spans fund commitments and direct property participation; the known asset base captured in corporate filings is concentrated in German commercial, residential, and mixed-use real estate held through multiple Gemelo-branded limited partnerships. The firm’s geographic focus stays squarely within Europe, with all identified property entities registered in Osnabrück and managed locally. Kotte & Cie keeps a deliberately low headcount and has not disclosed aggregate assets under management or total deployment. The Spiekermann & CO AG connection provides adjacent fund-management capabilities, and Sebastian Kotte’s chairmanship of the IHK Osnabrück-Emsland-Grafschaft Bentheim regional committee embeds the firm in the local business establishment. No team-size figure is published. There is no evidence of a separate venture-capital arm, a club-deal network beyond the IHK relationship, or a formalized co-investment program. The structural differentiator is the hybrid architecture: a multi-family office that doesn’t merely advise but co-owns real estate alongside one of its prominent principals. The shared Gemelo holding companies mean Kotte & Cie sits atop both a fiduciary-advisory layer and a set of joint asset-owning vehicles — a setup that blurs the line between family office and operating sponsor, giving the firm direct economic exposure to the portfolio it manages.

## Questions

### Is Kotte & Cie structured as a single family office or a multi-family office?

It operates explicitly as a multi-family office, serving several high-net-worth families from its Osnabrück base. The firm’s own materials use the term ‘Multi Family Office’ and describe coordinating across multiple client households for reporting, administration, and succession planning.

### How is Kotte & Cie related to Spiekermann & CO AG and the Gemelo entities?

Sebastian Kotte holds a board position at Spiekermann & CO AG, an Osnabrück-based asset manager. Meanwhile, Kotte & Cie principals share ownership of multiple Gemelo-branded real estate GmbHs with Hans-Heiner Müller, the founder of WM SE. This creates a tri-party relationship where the multi-family office, an external asset manager, and a set of co-owned property companies are linked through overlapping directors and shareholders.

### What is Kotte & Cie’s known posture on co-investments alongside external GPs?

There is no public evidence of a formal co-investment program with outside general partners. The only visible co-investing occurs inside the Gemelo real estate vehicles, where Kotte family entities and Hans-Heiner Müller’s interests sit alongside each other directly.
