ZeroTurnaround was a company specializing in Java development solutions, established in 2007 by Jevgeni Kabanov and Toomas Römer. The firm was purchased by Rogue Wave Software in 2017. Subsequently, in January 2019, Minneapolis-based software developer Perforce acquired Rogue Wave along with the original ZeroTurnaround product line.

History

The inception of ZeroTurnaround traces back to 2007 when founders Jevgeni Kabanov and Toomas Römer met while working at the IT services firm Webmedia (currently known as Nortal) in Tartu, Estonia. They began their partnership and enlisted David Booth as a marketing advisor in 2009; he was appointed CEO by March of that year. That same year, ZeroTurnaround was spun off as an independent entity with initial investment from Webmedia.

Kabanov’s doctoral dissertation titled Towards a more productive Java EE ecosystem was inspired by the project’s development. By the year 2014, ZeroTurnaround’s offerings were adopted by approximately 3,500 companies spanning over 80 countries.

On March 19, 2013, ZeroTurnaround expanded its portfolio through the acquisition of Javeleon, a Danish firm focused on enhancing Java developer efficiency.

Eventually, on November 29, 2017, Rogue Wave Software acquired ZeroTurnaround. Later, in January 2019, Perforce took ownership of both Rogue Wave and the legacy ZeroTurnaround product JRebel.

Products

ZeroTurnaround created JRebel, a plugin for Java integrated development environments designed to bypass build and redeploy steps within the Java EE development workflow. This technology was marketed under terms such as "hotpatching" or "dynamic application reloading." Additionally, the company developed LiveRebel, a tool facilitating live application rollout and rollback through proprietary version control mechanisms; however, LiveRebel was discontinued in 2014.

Funding

Initial seed capital amounting to $0.38M was secured from Webmedia during 2008/2009. This was followed by a Series A funding round in 2011 led by Bain Capital Ventures alongside Salil Deshpande. In January 2014, ZeroTurnaround obtained an extra $2.7M in financing with Bain Capital Ventures again leading the round. Furthermore, in March 2014, the company received a $3M loan from Western Technology Investment, resulting in total funding exceeding $6M that year.
