Inc. published its annual Inc 5000 list of fastest growing US private companies this week. Several firms covered by this newsletter made the list including Synthio, DiscoverOrg, RainKing, Zoominfo, and Pure Incubation. To qualify for the list, companies must be private and have at least $200,000 in 2013 revenue.

DiscoverOrg made the list for the seventh year in a row with 2016 revenues of $59.4 million, up $15 million. The firm is in a strong position to make the 2017 list as they closed 2016 with an ARR of $71 million. DiscoverOrg’s three-year Compound Average Growth Rate (CAGR) was 40%.

“Our mission remains focused on accelerating our customers’ pipeline and revenue growth—we can only grow when they grow,” said CEO Henry Schuck. “Since our inception 10 years ago, our customers have experienced the difference our unmatched data has on their own sales. Making the Inc. 5000 list for the seventh time is a reflection of their trust and of our mutual success.”

Along with financial growth, the company has continuously grown its editorial-based content while expanding the functional and integration capabilities of its service. While originally focused on providing company and IT executive profiles for US sales reps, the company has globalized its coverage, extended into marketing tools, and added additional job functions including sales, marketing, HR, and Product Management (TEDD) to its database. By including CRM and MAP connectors, analytical tools, and light predictive scoring, the firm has increased the value it provides to companies across a broader set of job functions (marketing, exec recruitment, strategic sales, and sales operations) and found additional ways to augment the value of each record. In so doing, they have been able to maintain a profitable, cash-flow positive growth trajectory over a decade.

“Only a tiny fraction of the nation’s companies have demonstrated such remarkably consistent high growth,” said Eric Schurenberg, President and Editor in Chief, Inc. Magazine. “This achievement truly puts DiscoverOrg in rarefied company.”

DiscoverOrg’s top competitor RainKing also made the list for the fourth consecutive year. 2016 revenue rose $6.9 million to $33.9 million. RainKing has a three-year CAGR of 29%.  Two weeks ago, DiscoverOrg acquired RainKing.

“This has been a transformational year for RainKing and this award is a recognition of the satisfaction of our customers and the accomplishments of our employees,” stated RainKing CEO John Stanfill. “We have had some significant accomplishments over the past twelve months which have helped fuel our growth, but the biggest factor in our success is our ability to help our customers grow their businesses faster.”

Among the recent content and platform enhancements were a new user interface, coverage expansion to 65,000 companies and one million executives, the launch of a Federal IT dataset, and rebranding. The firm also moved to larger office space in Bethesda, Maryland.

New York-based Madison Logic made the list for the fifth consecutive year with a three year CAGR of 43%. CEO Tom Regan said, “We’ve developed the only comprehensive account based marketing solution that unifies display advertising, lead generation and advanced measurement capabilities that enable marketers to achieve a quantifiable return on investment.”

Zoominfo, which was bought by private equity firm Great Hill Partners last week, had a three-year CAGR of 39% with 2016 revenue of $39.8 million. The firm successfully pivoted into marketing services a few years ago with contact data enrichment services, list building, web forms, segmentation analysis, and cluster analysis.
