Sipti Companies merges with Sweco

Published: 30.5.2025

Sweco signed an agreement at the end of the year to acquire Sipti Companies. As a result of the acquisition, Sipti Companies have combined their expertise with Sweco, and together, we offer our clients diverse and high-quality geo- and environmental expertise, as well as more extensive design services for the built environment and industry.

Sipti Oy , Sipti Environment Oy, Sipti Infra Oy, and Kymen Sipti Oy will merge on 31.5.2025 into Sweco Finland Oy (business ID 2661738-3). Subsequently, the Sipti companies will no longer exist as company names and and instead their operations will continue under the brand Sweco.

Employee email addresses will change to firstname.lastname@sweco.fi starting 1.6.2025. However, emails sent to sipti.fi addresses will be delivered for one year. Most of our experts will retain their phone numbers.

Our daily work continues as usual, and the merger will not require any action from our clients. Existing agreements remain in force, and ongoing projects will continue as usual. Additionally, our contact persons and project managers will remain unchanged.
