Who we are

Engineers, entrepreneurs and seasoned software veterans

Undo’s technology allows some of the biggest software companies to improve the quality of their products and fix customer issues quickly. We help our customers focus on the things that matter by reducing the time, pain and effort involved in building the world’s most complex software.

Undo is a fast-growing, venture-backed technology start-up based in Cambridge, UK, with offices in the USA. 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.
