When I first saw the solution, I thought there’s no way it could work this easily, but the very first channel I connected worked immediately. > > — Hector Chacon, Technology Change Management Analyst, OneMain Financial > We needed to bridge the communication between the client, client success, and internal operations. As founders, we wanted to use one app to forward our Slack client messages to our internal team quickly. Conclude is a perfect solution for consulting companies like us, improving project coordination and ensuring client success. > > — Shawn He, Chief Executive Officer, Black Compass > Previously, we used separate Slack accounts to communicate with external partners and Teams for internal communication. With Conclude, we were able to integrate both platforms, reducing the steps needed to communicate and share information. I strongly recommend this solution. > > — Min Lee, Director of IT, Komar > 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. > > — Patricia G, Operations Lead, Team TechGuru ## Reduce workplace chat silos Use a Slack and Microsoft Teams integration to [reduce workplace silos](https://conclude.io/blog/silo-mentality-is-the-enemy-of-collaboration-and-workplace-efficiency/).
