Undo allows Linux developers to see exactly what their program did at every step in its execution. From Raspberry Pi to Cray supercomputers, our products can be used at every scale, helping companies respond quickly to failures in production and test environments, increase their debugging productivity, and improve software quality.

Undo's journey continues to evolve.  It was founded by Greg Law and Julian Smith who worked on evenings and weekends in Greg's garden shed to create a better debugging tool than the commercial and open source solutions which had frustrated them for many years. Following receipt of seed funding in 2012, the company is now the leading commercial supplier of reversible debugging tools for Linux and a pioneer in developing solutions that help companies to better understand their software.

The company’s headquarters are located in Cambridge, UK, one of the world’s leading technology hubs, and its team is handpicked from some of the world’s leading universities.

Undo is backed by an experienced group of investors including Cambridge Innovation Capital (CIC), the Cambridge Angels, Rockspring, Martlet and Jaan Tallinn, co-founder of Skype and Kazaa.
