Undo is a software debugging company based in Cambridge, UK.
The company was founded in 2005 by Greg Law and Julian Smith.

[5][6][7] LiveRecorder was then developed based on UndoDB to enable development teams to record and replay the execution of software programs.
[8][9][10][11] In 2012, Undo secured its initial seed funding.
