## About

BTV Beteiligungsverwaltung was established in 1996 by Sebastian Thomas Stamm as the dedicated vehicle for the Stamm family. The office preserves and grows family capital through disciplined, long-term allocation. The firm follows an endowment model that spans private equity, real estate, public equity, hedge funds, natural resources, and private credit. It targets buyout, seed, Series A, Series B, and Series C stages and holds mixed-use real-estate portfolios in Munich under vehicles such as C2a Immobilien, M21 Immobilien, and BTV Gesellschaft für Grundbesitz. Geographic reach covers Europe with additional natural-resources exposure worldwide. Partnerships with external managers supplement direct holdings. The Munich headquarters employs more than thirty professionals who handle the majority of investment and administrative tasks in-house. Adjacent structures include Dorfleben Walchensee gemeinnützige GmbH and SWK Stiftung für Wissenschaft und Kultur GmbH. Sebastian Stamm also represents the firm in the Single Pair Ethernet System Alliance. Ownership remains within the Stamm family, with day-to-day management shared among family members and long-tenured external directors. This integrated governance model distinguishes the office from pure fund-of-funds or advisory platforms.
