Eleven for Business
What it is
Eleven for Business is encrypted chat for small businesses that want to keep conversations off outside servers. It includes 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 through a link and remove them when a job ends without provisioning guest accounts. Messages and attachments are encrypted on devices, and 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 is €0.00 per free, with every feature, up to 3 spaces and 1 GB of files per space. Business is €11.00 per year, billed annually, with 11 GB of storage per person pooled for the space.
