Everyone included, at one price

Microsoft sells Teams and Viva Engage per user, inside Microsoft 365. That works for employees who already have a license, less for volunteers, members, partners or frontline staff who do not. HumHub hosted by CUZY gives everyone a place for a flat price, with software you can take anywhere.
Microsoft Teams is the chat, meeting and file collaboration hub of Microsoft 365. Viva Engage (formerly Yammer) is its enterprise social network: communities and storylines come with Microsoft 365, premium features need a Viva license. Both are proprietary and priced per user.
Facts about Microsoft Teams and Viva Engage come from the vendor's own pages, checked in September 2026: Microsoft 365 business plans, Microsoft Teams Essentials, Microsoft Viva pricing, Viva Engage setup: core and premium, EU Data Boundary. Prices are those published by the vendor (US dollars, per user); they may have changed since. Tell us about an error on the contact page and we correct it.

HumHub runs on any server; the daily export takes your whole community with you. No vendor can change the terms under you.
Each space has a stream, a wiki, files, a calendar and tasks, so information stays findable instead of scrolling away in a channel.
Members can still sign in with Microsoft Entra ID through Keycloak, and keep Teams for calls and chat.
Microsoft Teams and Viva Engage are the better fit for an organization whose employees all have Microsoft 365 licenses and live in Outlook, SharePoint and Teams meetings every day: the social layer then comes at little extra cost and is integrated with everything else.
Start a free trial, import members and content with our help, connect your identity provider, and run both platforms side by side until you are ready. Subscribers can export everything from CUZY once a day, so the move is never a one-way door. Tell us about your current setup and we assess what can be carried over.
