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 San Francisco and Cambridge, UK. Undo 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 leader in software reliability solutions based on Software Flight Recorder technology. 

Unlike traditional approaches to software reliability, Undo's technology enables engineering teams to record and replay the execution of a software program and identify exactly what the program did at any point in time and why.
