Founder story

Zoom Phone was launched in 2019 by Zoom Video Communications, founded by Eric Yuan in 2011 in San Jose, California. Yuan originally founded Zoom to eliminate friction in video collaboration. Recognizing that enterprise customers were still burdened by legacy, hardware-dependent PBX phone systems, Zoom developed Zoom Phone as a cloud-native VoIP platform to unify voice, video, and chat in one workspace.
