Eleven for Business vs Teamwire

Eleven for Business is encrypted group chat for small businesses that want to keep conversations off another party’s servers. It supports spaces, groups, direct messages, file sharing, reactions, replies, threads, GIF search, and link previews. Spaces also offer scheduled reminders, morning summaries, and a helper that can answer questions and build small apps. The service works in a browser and has native Mac and iPhone apps; its business page also says it runs on warehouse Android devices. Businesses can invite clients by link and remove them when a job ends without provisioning guest accounts. Messages and attachments are encrypted on devices, while the server stores and relays ciphertext it cannot read. Self-hosting is available at no charge with the same apps and features. The Free plan costs nothing and includes every feature, up to three spaces, and 1 GB of files per space. Business costs €11 a year, billed annually, and provides 11 GB of storage per person, pooled for the space.

Teamwire is a secure business messenger and collaboration platform from Teamwire, headquartered in Munich and founded in 2014.

Teamwire states that it is GDPR-compliant, ISO 27001 certified, and BSI C5 tested, with user data, messages, and content stored exclusively on servers in Germany.
