Major institutional funding comes as Malwarebytes’ enterprise cybersecurity business gains significant traction

SAN JOSE, Calif. – January 21, 2016 – Malwarebytes™, the leading advanced malware prevention and remediation solution, today announced a $50 million Series B funding round from Fidelity Management and Research Company.*

Malwarebytes surpassed $100 million in annualized billings in 2015 and achieved its 31st consecutive cash flow positive quarter.

Founded in 2008 by Marcin Kleczynski, the company was bootstrapped until raising a $30 million Series A funding round in July 2014, led by Highland Capital Partners.

“Malware is an epidemic attacking  businesses and governments worldwide, as evidenced by recent high profile breaches,” said Marcin Kleczynski, CEO of Malwarebytes. “Of course, it’s an honor to be backed by Fidelity – the same company that has backed disruptive, high-growth privately held technology companies like Uber, Airbnb and SpaceX. Our unique business model has allowed us to attain rapid growth while driving consistent profitability and cash flow. We will continue to hire more talented engineers to help us fight malware and accelerate Malwarebytes’ strategic sales, marketing and future product initiatives in our fast growing enterprise business.”
