§ Private Profile · Cambridge, UK
UNDO is a technology company.
Undo provides time travel debugging solutions for software developers, primarily focused on the Linux environment. Its core product allows engineers to record and replay program execution, enabling precise analysis of complex code behaviors and accelerating the identification and resolution of bugs. This technology offers a unique approach to understanding software issues, particularly for applications written in C/C++ and Java.
The company was established in 2005 by co-founders Greg Law and Julian Smith, originating from Cambridge, UK. Their foundational insight stemmed from the challenges developers faced in diagnosing intermittent or complex software defects, leading them to pioneer a debugging paradigm that significantly reduces the time and effort traditionally spent on problem-solving. This innovation aimed to streamline the development workflow for critical systems.
Undo targets professional developers working on sophisticated software projects where reliability and efficiency are paramount. The company’s vision is to empower engineering teams with advanced tools that simplify the often-arduous process of debugging, thereby enhancing productivity and fostering higher quality software delivery. Its forward-looking mission centers on continuing to refine and expand these capabilities to meet the evolving demands of software development.
