Biography

Vlad Shmunis was born in Kiev, Ukraine, in 1960 and immigrated to the United States. He earned a B.S. in Electrical Engineering and Computer Science and an M.S. in Computer Science from San Francisco State University. Shmunis began his career in research and development, holding positions at prominent technology companies including Bell Labs, Amati Communications (acquired by Texas Instruments), and Glam Media. In 1999, Shmunis co-founded RingCentral with Martin De Beer. Initially, the company focused on providing a virtual phone system for small businesses, leveraging the nascent VoIP technology. Shmunis's early vision recognized the transformative potential of moving business communications from on-premise hardware to cloud-based software. This foresight allowed RingCentral to scale and innovate ahead of many competitors. Under Shmunis's leadership, RingCentral strategically shifted its focus from small businesses to mid-market and enterprise segments, developing a comprehensive Unified Communications as a Service (UCaaS) platform. This platform integrates voice, video meetings, team messaging, and contact center capabilities into a single, cloud-native solution. Key partnerships have been instrumental in RingCentral's growth, notably with Avaya (Avaya Cloud Office, ACO, launched 2020) and Alcatel-Lucent Enterprise (Rainbow Office, launched 2020), expanding its reach into established enterprise customer bases. RingCentral went public on the NYSE in September 2013 under the ticker RNG. Shmunis has continued to lead the company through periods of intense competition and technological evolution, emphasizing product innovation, strategic partnerships, and a strong focus on customer experience. His leadership has cemented RingCentral's position as a market leader in the UCaaS space.
