KnowBe4 Debuts at #139 on Inc. 500 List of America’s Fastest Growing Private Companies

(Tampa Bay, FL) –No stranger to hypergrowth, KnowBe4’s Founder and CEO Stu Sjouwerman marks his fifth startup a resounding success with its debut onto the prestigious Inc. 500 list at spot #139. In 5 short years, KnowBe4 has become America’s most popular integrated security awareness training and phishing platform, has seen explosive growth for 12 consecutive quarters and record numbers of new corporate accounts. This is Sjouwerman’s (pronounced shower-man) 2nd time on the Inc. 500 list, appearing with his prior company Sunbelt Software in 2001.

“We are very honored to be named to this list of fastest growing companies, and see it as an acknowledgement of our efforts to help our customers with an effective way to manage the ongoing problem of social engineering,” said Sjouwerman. “Our training and simulated phishing platform has been well received by IT managers. Customers are telling us continually that it has created a greatly improved employee security culture with our new-school Kevin Mitnick security awareness training. They feel safer knowing they can better protect their networks against phishing and ransomware infections,” added Sjouwerman.”

Inc. Magazine’s list represents a unique look at the most successful companies within the American economy’s most dynamic segment–its independent small businesses. The 2016 Inc. 5000, unveiled online at and with the top 500 companies featured in the September issue of Inc. (available on newsstands August 23) is the most competitive crop in the list’s history. The average company on the list achieved a respectable three-year growth of 433%. However, KnowBe4’s growth was over 2,500% over the most recent three-year period. Sjouwerman said: “With Kevin Mitnick’s subject matter expertise, we have a big advantage over anyone else out there. Kevin is the world’s most famous hacker.”

“The Inc. 5000 list stands out where it really counts,” says Inc. President and Editor-In-Chief Eric Schurenberg. “It honors real achievement by a founder or a team of them. No one makes the Inc. 5000 without building something great – usually from scratch. That’s one of the hardest things to do in business, as every company founder knows. But without it, free enterprise fails.”

KnowBe4 has taken advantage of the burgeoning security market, helping businesses manage the ongoing problem of social engineering. Cybercrime has gone pro with cyber mafias furiously innovating and creating methods to exploit organizations through the use of social engineering.

Ransomware has doubled and scams like the Business Email Compromise (BEC)–also known as CEO fraud– are costing the economy more than a billion dollars yearly according to the FBI, with a 1300 percent rise in losses since January 2015. KnowBe4’s CEO doesn’t see business slowing down anytime soon.
