RingCentral, Inc.

United States · NYSE: RNG ·Market cap:

RingCentral sells cloud-based phone and messaging services that let businesses talk to customers and each other over the internet instead of old-fashioned phone lines.

RingCentral is a business communications company. It sells cloud-based phone systems, video meetings, and team messaging to companies of all sizes. Instead of buying a physical desk phone and plugging it into a wall, a business signs up for RingCentral and its employees make and take calls from an app on a laptop or smartphone. The company charges a monthly subscription per user, and that recurring fee is the main way it makes money. It also sells add-ons like contact center software, which big customer service teams use to handle lots of incoming calls and chats. Think of it as the phone company for the internet age: the calls still happen, but the wires, hardware, and switchboard all live in the cloud.

Most of RingCentral's revenue comes from these subscriptions, and the bulk of it is recurring, which makes the business fairly predictable. It serves small businesses, mid-sized companies, and large enterprises. Customers choose it because it is cheaper and easier to manage than traditional phone systems, and because it works wherever employees are. A key part of the strategy is partnerships: RingCentral powers the phone features inside other popular software, so users can make calls without leaving the app they already use. That bundling helps it reach customers it might not win on its own. The company has been pushing into newer areas like AI-powered call summaries and virtual agents that can answer simple customer questions. It has also worked to make its contact center product a bigger part of its business, since that market is large and growing. RingCentral competes with other cloud communications providers as well as with giant tech platforms that bundle calling into their own suites. It is headquartered in Belmont, California, and went public in 2013. Like many software companies, it has focused on growing revenue and retaining customers, and it uses its cash to invest in new products and to buy smaller companies that add useful technology.
