SISCOG is a Lisbon software company, founded in 1986, that builds AI-driven crew- and fleet-scheduling systems for railways and metros. Its CREWS and ONTIME products are used by Nordic state railway operators including Denmark’s DSB, Norway’s Vy (formerly NSB) and Finland’s VR.
SISCOG has spent more than three decades exporting resource-optimisation software to European rail operators. Founded in Lisbon in 1986, it pioneered the use of artificial intelligence for crew rostering and rolling-stock planning, and its CREWS and ONTIME systems are now embedded in the operations of railways across Europe and North America.
In the Nordics, SISCOG’s systems plan crews and fleets for Denmark’s state operator DSB, Norway’s Vy (formerly NSB) and Finland’s VR — three of the region’s largest railway companies. Rail-scheduling software is mission-critical and long-cycle: once installed it tends to stay in service for many years, making SISCOG a deeply embedded, if low-profile, Portuguese supplier to Scandinavian public transport.
SISCOG is one of the strongest examples of a Portuguese knowledge-economy exporter winning and keeping demanding public-sector clients in Scandinavia. It shows that the Portugal-to-Nordics corridor is not only about wine, cork and tiles, but also about high-value software quietly running critical Nordic infrastructure.
Fractio helps Portuguese B2B companies build the Nordic relationships, references and operational footprint they need to win in Sweden, Denmark, Norway and Finland.
