Malwarebytes said it posted record annual recurring revenue growth in fiscal 2020, signaling stronger subscription momentum. The company also said its active managed services partner base grew more than 50% in less than three months.
Malwarebytes says its software is built to protect businesses and consumers from malicious threats that consistently escape mainstream solutions. The company has evolved from a device cleaner into proactive malware monitoring and web traffic protection, broadening its security stack.
Built In says Malwarebytes is doubling down on SMB and MSP customers through its ThreatDown push in 2026. That focus points to a large addressable market of smaller organizations that need managed security but often lack enterprise-grade resources.

No. As of March 2026, Malwarebytes is a private company and does not trade on any public stock exchange. Accredited investors can access Malwarebytes shares through UpMarket, a FINRA-registered broker-dealer that specializes in pre-IPO investments.
Malwarebytes does not have a public stock price because it is privately held. The most recent known share price comes from its last funding round. Pre-IPO share prices on the secondary market may differ from the last round price depending on supply, demand, and market conditions.
Yes. Accredited investors can indicate interest in Malwarebytes shares through UpMarket by filling out the form on this page or creating an account at upmarket.co. All pre-IPO offerings are subject to availability and require a $50,000 minimum investment. UpMarket is a FINRA-registered broker-dealer and has brokered alternative investments since 2019.
Pre-IPO investments carry significant risks. Malwarebytes shares are illiquid, meaning there is no public market to sell them quickly. There is no guaranteed exit timeline or return. The investment is speculative in nature, and investors should be prepared for the possibility of total loss. Valuations of private companies can fluctuate substantially between funding rounds. Investors should consult their financial advisor and review all offering documents before investing.
In a pre-IPO transaction, accredited investors purchase shares from existing shareholders (such as employees, early investors, or other holders) through secondary market platforms. The company itself does not issue new shares in these transactions. UpMarket facilitates these trades as a FINRA-registered broker-dealer, handling compliance, documentation, and settlement on behalf of both parties.
There are two primary exit paths for pre-IPO holdings: selling your shares on the secondary market to another buyer, or holding until the company completes an IPO or is acquired. Both paths are subject to transfer restrictions, company approval (right of first refusal), and market conditions. The timing of any exit is unpredictable, and investors should plan for a multi-year holding period.
The minimum investment for most pre-IPO offerings on UpMarket is $50,000. This amount may vary depending on the specific offering and share availability. There are no fees to create an UpMarket account or browse available investments. Investors only pay transaction-related fees when they complete an investment.
UpMarket's valuation estimate is derived from a proprietary model that incorporates multiple data sources: funding round data (Caplight), revenue estimates (Sacra), secondary market pricing, and public company comparables. The model applies a private company discount to the public comp multiple to account for illiquidity and information asymmetry. This estimate is not investment advice and may differ substantially from the price at which shares actually trade.
Malwarebytes makes malware removal, anti-exploit, and privacy protection software for consumers and businesses and exited fiscal 2020 with over $190M in ARR, after reporting record ARR growth. Accredited investors can access Malwarebytes stock through UpMarket.
