Founder story
Fuze was founded in 2006 by Steve Kokinos and Derek Yoo in Boston, Massachusetts. Originally launching as ThinkingPhone Networks, they aimed to tackle the complexity of internal corporate communications by moving the entire telephony and collaboration suite to the cloud. Over nearly two decades, the company evolved into a leader in enterprise UCaaS before being acquired by 8x8 in 2022 to strengthen its position in the unified communications marketplace.
