Conclude’s collaboration solutions
Whether you need to connect internal teams or align with external clients, Conclude does both.
Need more than chat and channel connections? Conclude also solves ticketing and issue management with apps for Slack and Microsoft Teams. See Conclude Apps or our customer support solution, for more.

“Conclude has significantly improved our collaboration with external companies and clients. We use Teams, and previously faced challenges when customers preferred using Slack. This either forced us to run multiple tools or abandon chat as a communication method. Conclude has provided a reliable solution that allows our customers and team to use their preferred tools, enabling real-time communication without any drawbacks."
