Fuze

Other B2B Software · Boston, United States · Founded 2006

A global cloud communications and collaboration software platform for the enterprise MoreLess

Fuze, initially established as ThinkingPhones in 2006 by Steven Kokinos and Derek Yoo, has carved out a significant space in the enterprise communications sector. The company's trajectory was notably shaped by its rebranding to Fuze in 2016, a move that followed a substantial $112 million funding round and signaled a strategic shift towards a unified communications platform. This evolution was driven by the vision of its founders, with Steven Kokinos, who served as CEO, bringing a background from BladeLogic, a data center automation company acquired by BMC Software. This experience in enterprise-grade software and infrastructure was pivotal in scaling Fuze's offerings for large-scale business clients.

The core of Fuze's business is providing a cloud-based communications platform designed for large enterprises. This platform integrates voice, video conferencing, messaging, and contact center capabilities into a single application, aiming to streamline communication and collaboration for a global workforce. The business model is structured around a Software-as-a-Service (SaaS) subscription, generating recurring revenue by licensing its platform to corporate clients. Fuze targets organizations with complex, often international, communication needs, offering a centralized solution to replace fragmented, legacy systems. The platform's architecture allows for voice and video calls, individual and group chat, content sharing, and full contact center operations, accessible from desktop and mobile devices. A key selling point is its ability to support a seamless transition between these communication modes within one interface.

In a significant market development, Fuze was acquired by 8x8, a fellow competitor in the Unified Communications as a Service (UCaaS) market, in a transaction announced in late 2021 and completed in early 2022. The deal, valued at approximately $250 million in stock and cash, was a strategic move by 8x8 to enhance its enterprise-focused capabilities and expand its customer base. The acquisition marked the culmination of Fuze's journey as an independent entity, integrating its technology and operations into the 8x8 eXperience Communications Platform.
