WEB2013_500x500_yritys_historiaOur company was founded in 1976 in the midst of the oil crisis. For many design offices, the oil crisis meant leaner times, and it bankrupted the Finnish unit of a larger Swedish engineering company. It was from these remains, that eight young employees founded the Suomalainen Insinööritoimisto Oy (Finnish Consulting Engineers ltd.), Sito in short. For 40 years, the company has grown from a handful of employees to a multitalented corporation of more than 500 employees.

The engine behind this steady growth has always been the fearless development of solutions for information technology and sound long-term company policies.
