About Me

Do it right the first time, do it fast, and have fun while you do it.

Stu Sjouwerman (pronounced “shower-man”) is the founder and CEO of KnowBe4, Inc., which hosts the world’s most popular integrated Security Awareness Training and Simulated Phishing platform.

Born in Amsterdam, Holland where all my family still lives. I lived in Paris, France from 1989 to 1993 and then moved to Florida. Married to Rebecca, an artist from Sweden, since 1989. I'm fluent in Dutch, English, German and French.

I'm a voracious reader, mostly Sci-Fi but also biographies, and books about the financial markets. I have dozens of e-books now, and used to read them on my Amazon Kindle, but have changed over to reading them on my iPad which I love!

My fave early-years Sci-Fi authors are Robert Heinlein, Asimov, L.Ron Hubbard, and Arthur Clarke. More recent writers I like a lot are Neil Stephenson, William Gibson, and recently I discovered Charles Stross who originally is an IT-guy and it shows in his novels!

Been in IT since 1979 and still love the fast pace. I'm starting my fifth IT company this year. You could call me a serial ITpreneur! :-)

A serial entrepreneur and data security expert with more than 30 years in the IT industry, Sjouwerman was the co-founder of Inc. 500 company Sunbelt Software, a multiple award-winning anti-malware software company that was acquired 2010.

Realizing that the human element of security was being seriously neglected, Sjouwerman decided to help organizations manage the problem of cybercrime social engineering tactics through new school security awareness training and founded KnowBe4.

30,000+ organizations in a variety of industries, including highly-regulated fields such as healthcare, finance, energy, government and insurance have mobilized their end users as a first line of defense using KnowBe4.

Sjouwerman is the author of four books, with his latest being “Cyberheist: The Biggest Financial Threat Facing American Businesses.”.

From 1996 through 2011, Stu was the Editor-In-Chief of WServer News, an email newsletter to 100,000+ IT system administrators helping them to keep their systems secure. Along with his CEO duties, Stu is currently Editor-in-Chief of Cyberheist News, an e-zine tailored to deliver IT security news, technical updates and social engineering alerts to IT professionals.
