Membrain: sovereignty score and 8 European alternatives

Membrain is a B2B platform that combines CRM and sales enablement, aimed at companies with complex sales, long cycles and multiple stakeholders, mainly mid-sized to large organisations. It supports prospecting with playbooks, management of the active pipeline, account planning, coaching and development of sales staff, and an AI layer built on the customer's own sales process. Analytics, quotes, automations and integrations are also available. Membrain is delivered as a cloud service.

Membrain is a Swedish company: its legal entity, Upstream Business Solutions AB, is based in Stockholm. According to its sub-processor list, Google hosts the production systems in the US or in Europe (Sweden), and the customer can select the region. The privacy policy also names AWS and Microsoft and notes that data may be processed outside the EU/EEA; for AI features it lists US-based sub-processors, including OpenAI and Anthropic. Membrain is not open source. A European organisation should have the European region contractually fixed and review the sub-processors.

Why digital sovereignty matters with Membrain

Membrain is headquartered in SE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Membrain hosts data in EU, US. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Membrain 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 Membrain together with your other vendors and gives a total score, a heatmap and the main risk drivers.
