Caliza Holding

Caliza Holding

Caliza Holding AG was established in 2013 to manage the Marti family's holdings tied to Kalkfabrik Netstal AG, Switzerland's sole high-purity lime producer founded in 1900. Konrad Marti serves as Chairman and CIO while also heading corporate development at the operating company. The structure keeps decision-making inside the family with board participation from Kaspar Marti and Balthasar Marti. The office deploys across private equity, natural resources and direct co-investments. Asset classes include manufacturing, energy transition projects and mixed-use real estate. Confirmed holdings encompass Plazza AG in Zurich and Lausanne plus the Netstal industrial site. Geographic reach covers Europe, North America, Asia, Africa, South America, Oceania and the Middle East. The firm also participates in club-style arrangements alongside the Auer, Schmidheiny and Spoerry families in Bystronic AG and Plazza AG. Team size and total deployment remain undisclosed. Adjacent vehicles include the Baumgartenalp Stiftung and two Kalkfabrik Netstal foundations. Konrad Marti holds board roles at Glarner Kantonalbank and local chambers of commerce. No operational events from the last 24 months appear in public records. Ownership stays concentrated within the Marti family, with governance tied directly to the lime production business rather than external managers. This integration shapes capital allocation toward long-horizon industrial assets and local network co-investments.
