The market leader for payroll SW systems in Sweden needed to upgrade their architecture to a future proof web-based solution.

Magnus Beer, CEO, SevenDay

Custom Development

LeanDev has since its inception been in the frontline of developing mission-critical IT systems.

Custom development is the way to go if you have unique business requirements that are not supported by the standard systems available on the market. Or if you have an entirely new concept that requires system support that is not available today.
