the problem

The problem it solves#

Workplace chat is critical infrastructure, but most teams rent it from a single proprietary vendor. That creates lock-in around accounts, message history, integrations, pricing, and data residency.

XMPP offers a federated messaging foundation, but many XMPP clients feel built for hobbyist chat rather than workplace collaboration. Prose aims to bring a modern team-communication experience to that open protocol base.

how Prose solves it

How it solves it#

XMPP-based communication

Secure team messaging

The product focuses on private team communication, including chat history and file-sharing workflows.

Workplace collaboration features

Search, integrations, and team-oriented messaging features help position Prose beyond a basic chat client.
