reamis: sovereignty score and 8 European alternatives

reamis is a software suite for real estate asset and portfolio management from reamis AG of Baar, Switzerland. It is aimed at professional property owners and managers such as cities, pension funds, real estate funds, family offices and service companies. The suite combines dashboards and periodic reports, property planning with a ten-year plan for investments and income, strategy and scoring of properties, project controlling, and sustainability monitoring of energy use and CO2 reduction. Further modules cover indirect investments, building rights and project development. The vendor offers reamis as a cloud solution and as an on-premise installation.

reamis AG has its head office in Baar in the canton of Zug and a development site in Winterthur. Switzerland is not an EU member state but is an EFTA country with a European adequacy decision for data protection. The website names no parent company. The vendor does not state where the cloud variant hosts data, so ask the vendor. With an on-premise installation you choose where the data sits. Portfolio data of real estate investors is often confidential.

Why digital sovereignty matters with reamis

reamis is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

reamis runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

reamis is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs reamis together with your other vendors and gives a total score, a heatmap and the main risk drivers.
