Outside EUCollaborationFreemiumEU data storage ✓ISO 27001
All-in-one for chat, video meetings and collaboration, deeply integrated in Microsoft 365 with EU Data Boundary for data storage within EU/EFTA. Microsoft is however an American company under the Cloud Act, and the interface is often perceived as cluttered and resource-demanding.
Full EU Data Boundary: customer data stored and processed within EU/EFTA
Included in Microsoft 365 that most Swedish organizations already pay for
American parent company, Cloud Act applies despite EU Data Boundary
Best for: Organizations already using Microsoft 365 that want chat, meetings and files in one package
Swedish team chat with channels, direct messages as well as voice and video calls, running on Webbfabriken's own servers in Stockholm. Drawback: small vendor and a young service without a large ecosystem of integrations.
All data is stored in Stockholm, built and run by a Swedish company
Free for now, with core features such as channels, video and file sharing
Small vendor: long-term future and pricing model unclear (free now, paid tiers may come)
Best for: Small Swedish teams that want all chat data to stay in Sweden without American cloud.

Open-source team chat that can run entirely on your own servers in the EU. The cloud service is however in the USA (AWS us-east-1), the company is American (Palo Alto) and self-hosting requires technical skills.
Open source, can be self-hosted freely with full data control
EU data storage possible via self-hosting or managed partner
Cloud service stores data in the USA (AWS us-east-1), American parent company with CLOUD Act risk
Best for: Technically skilled teams that want to self-host a Slack-like chat on their own EU servers.
EU/EEACollaborationFreemiumEU data storage ✓ISO 27001
