History
The company was founded in 1989. In April 2006, the US based Keynote Systems acquired SIGOS for US$30 million, renaming it 'Keynote SIGOS'.

In June 2015, SIGOS' owner Keynote Systems merged with Dynatrace, the latter having John Van Siclen as acting CEO.

In January 2016, Keynote SIGOS acquired Keynote DeviceAnywhere, a company located in San Mateo, California that is specialised in testing of mobile applications (apps). They rebranded the DeviceAnywhere product as 'App Experience' (abbreviated AppEx) shortly afterwards.

In 2017, the company's name was simplified into SIGOS.

In July 2020, SIGOS was taken over by Mobileum who had already acquired WeDo Technologies earlier on in 2019. The SIGOS portfolio was integrated within the Mobileum offering under the Testing and Service Assurance banner.
