Marathon Technologies was founded by senior executives and engineers responsible for developing Digital’s VAX FT fault-tolerant systems. The team used this experience to create the first software and networking technology that allowed multiple Windows/Intel servers to operate as a single fault-tolerant system.

The company migrated its technology in 2004 to a software-only product (everRun®) that works with standard off-the-shelf x86 Intel and AMD servers with Windows Server 2003 and unmodified Windows applications. In 2007, the company announced its v-Available product initiative, designed to fill a big gap in the market for effective high availability software for virtual servers. In the spring of 2008 the company released everRun VM for Citrix XenServer^TM the first in the series of v-Available products from Marathon that are so simple, transparent and effective that every application can have high availability and disaster recovery protection.
