simus classmate: sovereignty score and 8 European alternatives

simus classmate is a software suite from simus systems GmbH for the manufacturing industry, especially mechanical engineering. Its modules bring structure to master data and CAD data: automatic classification of CAD models, creating and maintaining material master data, finding geometrically similar parts, analysing technical drawings, generating texts and assigning customs tariff numbers. The suite also calculates costs and emissions directly from the 3D model and supports project cost control and the creation of routings. There are connections to ERP, CAD and PLM systems, including SAP.

The vendor is based in Karlsruhe, Germany, and names no parent company in another country on its website. The software can be installed locally, used as a cloud platform (simus connect) or combined in a hybrid setup; according to the vendor, the functionality is the same. The website does not say where cloud data is stored or whether a data processing agreement exists; ask about this, because design data is commercially sensitive. For a European organisation the local variant gives full control over the data.
