ZOOMINFO

In 2007, Henry Schuck was a law student. He and his co-founder Kirk Brown each put $25,000 on their personal credit cards and started a company called DiscoverOrg out of a dorm room.

The idea was unglamorous but valuable. Build the most accurate database of who works where, what they do, and how to reach them.

Sales teams were desperate for this. They were wasting time chasing wrong numbers and dead emails.

DiscoverOrg sold them clean, verified data instead. For over a decade Schuck grew it the hard way, one subscription at a time, far from Silicon Valley in Vancouver, Washington.

ZoomInfo sells access to a giant database of business people and companies. A sales or marketing team pays an annual subscription to look up contacts, find direct phone numbers and emails, and see which companies might be ready to buy.

The pricing is per seat and it is not cheap, often tens of thousands of dollars a year for a team. That is the model.

Charge companies a recurring fee for the contact data that helps them sell. The better and fresher the data, the more they can charge.

The core product is the ZoomInfo platform, a searchable database of hundreds of millions of business contacts and millions of companies. On top of that it sells intent data, which tries to spot which companies are actively researching a product and might be ready to buy.

It also offers tools for sales engagement, website visitor identification, and talent recruiting, many added through acquisitions. The pitch is a single source of truth for go-to-market teams.

In 2025 the company even changed its stock ticker to GTM, short for go-to-market, to drive the point home.

ZoomInfo's biggest growth move was buying its way to the top. In 2019, DiscoverOrg acquired its rival Zoom Information and took its more famous name.

That instantly combined two of the largest contact databases into one. The company kept making acquisitions to add features like website visitor tracking and conversation analysis.

It also got good at land-and-expand. Get one team inside a company hooked, then sell the data to marketing, recruiting, and operations too.

Buy rivals, bolt on features, and grow the accounts you already have. That is the playbook.

Privacy is the elephant in the room. ZoomInfo's entire business is collecting and selling personal contact information, often without the person knowing.

That invites lawsuits and tough regulation. The company has faced legal challenges over how it uses people's data, and laws like Europe's GDPR and California's privacy rules are a constant threat.

The other challenge is cheaper competition. Upstarts like Apollo offer similar data for a fraction of the price, squeezing ZoomInfo from below.

After a high-flying IPO, the stock fell hard from its peak as growth slowed. Defending both its prices and its data practices is the daily battle.

Before going public, ZoomInfo was backed by serious private equity. TA Associates invested in 2014.

The Carlyle Group and 22C Capital came in around 2018 and 2019 to help fund the merger with Zoom Information. When it filed to go public, the IPO drew big institutional investors like BlackRock, Fidelity, and Dragoneer.

JPMorgan and Morgan Stanley led the offering. The June 2020 IPO raised $935 million and valued the company at roughly $8.3 billion, a huge debut for a company that started on two credit cards.
