The company, backed by private equity firm KKR & Co Inc, gained a valuation of $3.56 billion in afternoon trading when its shares were up 33%. They opened at $19.95, above the initial offering price of $16.
KnowBe4 on Wednesday priced its offering of 9.5 million shares at the lower end of a range announced earlier, for a total raise of $152 million. Excluding proceeds from shares offered by the selling stockholders, the company would receive around $144 million.
Founded in 2010 by Stu Sjouwerman, KnowBe4 allows clients to simulate phishing attacks on their employees and check how well they are protected. It also offers security awareness training.
A part of the proceeds would be used to expand further into international markets including the United Kingdom and Japan, Sjouwerman said.
The debut for the Clearwater, Florida-based firm comes at a time of frenetic activity in U.S. capital markets, with tech firms including cryptocurrency exchange Coinbase Global Inc and automation software provider UiPath Inc witnessing solid market debuts.
Demand for KnowBe4's services increased during the COVID-19 pandemic, as companies spent more to protect the IT systems of employees working from home.
"It's going to take a long time before things return to normal and people come back to office, so we don't see a major change in the growth trajectory in the near future," Sjouwerman said.
Reuters reported on the company's IPO plans last year.
Morgan Stanley, Goldman Sachs, BofA Securities and KKR Capital Markets were the lead underwriters for the offering.
