Vlad Shmunis founded RingCentral with the idea of using the power of cloud technologies to reimagine business communications. The company vision is to deliver customer-first solutions that meet the needs of the rapidly changing business environment. RingCentral enables the modern workforce to communicate, collaborate, and connect from anywhere, on any device using any form of communication. The focus is to deliver flexible and cost-effective solutions that disrupt the business of legacy on-premises phone systems, while providing other important communications capabilities. With the delivery of RingCentral’s mobility-centric cloud communications solutions, RingCentral unifies voice, video, team messaging and collaboration, conferencing, online meetings, and integrated contact center. Today, RingCentral is the #1 cloud communications provider, used by more than 350,000 businesses worldwide. 
RingCentral is recognized as the largest and fastest-growing global pure-cloud communications solutions provider.

Under Shmunis, RingCentral has evolved from a startup company, funded in 2006 with a $12 million series A round led by Sequoia and Khosla Ventures, to a publicly traded NYSE listed company with a market cap of more than $10 billion.
