Fuze (discontinued)

Fuze was a global Unified Communications as a Service (UCaaS) platform that integrated enterprise voice calling, video conferencing, team messaging, and content collaboration into a single cloud application suite. Originally founded as ThinkingPhones before rebranding to Fuze, the platform served enterprise and mid-market organizations across desktop and mobile devices. Enterprise cloud communications provider 8x8, Inc. acquired Fuze in January 2022, subsequently absorbing its customer base and technology assets. Standalone service for the Fuze platform was officially discontinued and sunsetted on December 31, 2025. The listing is retained as a legacy record to preserve historical user reviews and research data.

Cloud Voice & VoIP Telephony

Fuze provided enterprise-grade voice-over-IP (VoIP) telephony that replaced traditional on-premises Private Branch Exchange (PBX) hardware. The platform supported global direct-inward-dialing (DID) numbers, carrier-grade call routing, interactive voice response (IVR) auto-attendants, call queues, visual voicemail, and centralized extension management. Built-in analytics allowed IT administrators to monitor call quality metrics, network latency, and voice usage trends across global locations.

Web and Video Conferencing & Remote Meetings

The platform featured high-definition (HD) audio and video conferencing capabilities for multi-party online meetings, virtual presentations, and team huddles. Users could initiate video meetings directly from chat threads or calendar invites, share desktop screens, present slide decks, and record meeting sessions to cloud storage.

Enterprise Team Messaging & Presence Management

Fuze provided real-time 1:1 and group team messaging channels for persistent workspace collaboration. The messaging interface supported file attachments, rich text formatting, inline message search, and presence status indicators (such as available, in a call, or in a meeting) synchronized automatically across connected user devices and calendar integrations.

Mobile & Desktop Application Suite

The platform delivered unified client applications across Windows, macOS, iOS, Android, and web browsers, enabling employees to transition between voice calls, video meetings, and chat threads across devices. Headquartered in Boston, Massachusetts, Fuze operated regional offices and data centers across North America, Europe, and Australia prior to its acquisition.

Acquisition & Discontinuation Status

In January 2022, 8x8, Inc. completed its acquisition of Fuze. 8x8 maintained and supported the platform during a multi-year transition period while migrating enterprise customer accounts over to the 8x8 XCaaS (eXperience Communications as a Service) platform. Standalone Fuze platform services and client applications were officially sunsetted and shut down on December 31, 2025.
