Founded by former Cisco engineer Eric Yuan, Zoom offers an easy-to-use platform for videoconferencing, serving enterprise, consumer, and educational customers. With features like one-on-one meetings, group video conferences, screen sharing, and recording, Zoom is used in various industries including education, healthcare, government, and financial services. The platform can accommodate up to 1,000 video participants and 10,000 viewers for a single meeting. Zoom also offers a unified communications as a service (UCaaS) platform called Zoom United, which combines video meetings, chat, VoIP phone service, video webinars, and Zoom Rooms. The company saw a significant increase in users during the COVID-19 pandemic, leading to a valuation of $100 billion. However, Zoom has faced criticism and scrutiny over privacy and security concerns, prompting the acquisition of Keybase to address these issues.
