Company History and Business Evolution

Malwarebytes was founded in 2008 by Marcin Kleczynski and Bruce Harrison after Kleczynski’s own computer was hit by a stubborn rootkit that traditional antivirus software failed to remove. Frustrated by the lack of effective solutions, Kleczynski developed a new scanning engine that used heuristics to detect and eliminate previously unknown threats. The first version, Malwarebytes Anti-Malware, gained rapid traction through positive word-of-mouth on tech forums. In 2009, the company released version 1.0, which quickly became one of the most downloaded security tools on the web. By 2011, Malwarebytes had surpassed 100 million downloads and was recognized by PC Magazine as the best free anti-malware software. The company’s growth accelerated with the introduction of premium consumer products and business solutions. In 2016, Malwarebytes acquired two cybersecurity firms—Hackmageddon and ThreatDown—to strengthen its threat intelligence capabilities. The same year, it launched Malwarebytes for Business, a cloud‑based endpoint detection and response (EDR) platform. In 2017, the company raised $30 million in Series B funding led by Fidelity Investments, valuing the company at over $1 billion. The following year, Malwarebytes relocated its headquarters to Santa Clara to tap into Silicon Valley’s talent pool. In 2019, the company introduced its Managed Threat Detection service, combining human expertise with AI. The COVID‑19 pandemic in 2020 drove a surge in remote work, and Malwarebytes responded by enhancing its VPN and mobile security offerings. In 2021, the company went public via a SPAC merger with a special purpose acquisition company, raising over $300 million. This IPO provided capital for further R&D and acquisitions, including the purchase of SaferPass (a password manager) in 2022. Today, Malwarebytes employs over 2,000 people and serves customers in 195 countries. Its evolution from a single‑purpose anti‑malware tool to a comprehensive cybersecurity platform exemplifies adaptability and innovation. The company continues to invest in machine learning, cloud security, and automated response technologies to stay ahead of adversaries. Key milestones include reaching 100 million downloads in 2011, launching business products in 2017, and achieving $400 million in annual recurring revenue by 2023. Malwarebytes’ history is marked by a relentless focus on user experience and effective threat removal, earning it a loyal customer base and numerous industry awards.
