Retrium: sovereignty score and 8 European alternatives

Retrium is a web tool for agile retrospectives. Teams work through a guided session from gathering input to deciding on actions, using ready-made formats such as Start/Stop/Continue, Mad Sad Glad and Lean Coffee, as well as custom formats. The tool offers private brainstorming, anonymous comments, grouping of topics into themes, voting to prioritise, action plans and a history of earlier retrospectives. It can be used in real time or asynchronously and integrates with other tools. Retrium is delivered as SaaS.

Retrium's website names no legal entity or headquarters and describes the team as fully distributed; the company is treated as US-based. Data is stored with Amazon Web Services in data centres in the United States, and the region is not disclosed. Retrium states that it is fully compliant with the GDPR and offers a data processing addendum that can be signed electronically and incorporates the EU standard contractual clauses. A European organisation should take into account that retrospective data is stored in the US.

Why digital sovereignty matters with Retrium

Retrium is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Retrium hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Retrium is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

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