## About

Founded in 2012 by CEO Greg Law and headquartered in Cambridge, UK, Undo Ltd. focuses on providing innovative debugging solutions. In June 2026, Undo Ltd. raised USD 37 million in venture funding led by Elsewhere Partners with participation from EMV Capital.

Undo specializes in time travel debugging solutions for programming languages such as C/C++ and Java. Their flagship product, UndoDB, empowers developers to reverse application execution to pinpoint and rectify bugs in complex code without traditional debugging methods. This tool is utilized by software development firms, gaming companies, and technology startups, with a primary focus on markets in North America, Europe, and Asia. Undo's solutions improve debugging efficiency, software quality, and overall productivity for organizations.

The company utilizes a subscription-based model for revenue, providing annual licensing for its core debugging solutions, including UndoDB, which fosters long-term relationships with enterprise clients and ensures predictable revenue streams.

The company plans to utilize the June 2026 funding to expand globally, grow its teams, and integrate its debugging technology into AI-generated code tools.
