The record

Purpose: Eleven for Business is encrypted chat for small businesses that want to keep their plans off someone else’s servers.
Chat features: It supports spaces, groups, direct messages, file sharing, reactions, replies, threads, GIF search, and link previews.
Built-in tools: Spaces include scheduled reminders, morning summaries, and a helper that can answer questions and build small apps.
Client access: The product works in any browser and has native Mac and iPhone apps; the business page says it runs on warehouse Android devices too.
Inviting clients: Businesses can invite clients with a link and remove them when the job ends, without provisioning guest accounts.
Encryption: Messages and attachments are encrypted on devices, and the server stores and relays ciphertext it cannot read.
Security limits: Removing a member does not revoke their access to past messages, and losing the only device with unsaved keys can make that history unrecoverable.
Privacy and billing: Chat requires no email or phone number, while paying customers provide a billing email and pay through Stripe, which handles card details.
Integrations: GIF search sends search terms directly from the device to Giphy; the privacy page says Giphy can see the terms and the user’s network address.
Self-hosting: Businesses can self-host the service at no charge using a server program, with the same apps and features.
Intended users: Eleven describes itself as a group chat messenger for families, communities, and businesses, built by two software developers.
