ZoomInfo went public under a name it had bought. The company began in 2007 as DiscoverOrg, and in 2019 it acquired its rival Zoom Information and took its name. Its product was a database of businesses and the people who work there, with titles, emails, and phone numbers. Salespeople used it to find out who to call. ZoomInfo filed for its IPO in the spring of 2020, as the pandemic pushed nearly every sales team onto phones and video calls.

From DiscoverOrg to ZoomInfo

Henry Schuck and Kirk Brown founded DiscoverOrg in 2007. It sold contact data to sales teams that needed to know who made buying decisions at each company. DiscoverOrg bought rivals and tools for checking email addresses, including RainKing, NeverBounce, and Datanyze. Then it bought Zoom Information, a company founded in 2000 as Eliyon Technologies. Customers paid yearly subscriptions to search the combined data.

A New Ticker Named GTM

ZoomInfo sold 44.5 million shares at $21 each in June 2020, raising about $935 million on Nasdaq under the ticker ZI. Later it bought Chorus.ai and other tools that listen to sales calls. The company has faced lawsuits over how it collects personal data and over what it told investors. In May 2025 it changed its ticker to GTM, short for go-to-market. ZoomInfo still trades on Nasdaq and bought DoubleO.ai in 2026.
