The S3 story

S3 Technologies was founded by three university friends, Simon, Marc and Vince, who all graduated in Computer Engineering from Université de Montréal – École Polytechnique de Montréal in 2002.

A shared passion and flair for entrepreneurship and IT made them take the plunge, and in 2003, S3 Technologies was founded. Starting under very humble conditions – to say the least – they each worked from their apartments in the early days. However, the mission was clear: To become the number one IT service provider in Canada by offering impeccable and productivity-driven IT infrastructure services to SMB’s throughout the country.
