Zoom Video Communications, Inc. is an American communications technology company headquartered in San Jose, California. It provides videotelephony and online chat services through a cloud-based peer-to-peer software platform used for video communications, messaging, voice calls, conference rooms for video meetings, virtual events and contact centers, and offers an open platform allowing third-party developers to build custom applications on its unified communications platform. Eric Yuan, a former Cisco engineer and executive, founded Zoom in 2011, and launched its software in 2013. Zoom's revenue growth, and perceived ease-of-use and reliability of its software, resulted in a $1 billion valuation in 2017, making it a "unicorn" company. The company first became profitable in 2019, and completed an initial public offering that year. The company joined the NASDAQ-100 stock index on April 30, 2020. Beginning in early 2020, Zoom's software usage saw a remarkable global increase after quarantine measures were adopted in response to the COVID-19 pandemic. Its software products have faced public and media scrutiny related to security and privacy issues. Wikipedia
