5th floor is specialized in custom software development and legacy system modernization. Since 2017, we've been accelerating digital transformation for demanding organizations, particularly in the public sector, through tailor-made applications built with and for their users.
Since 2025, our platform L4F (Legacy for the Future) transforms critical legacy systems into strategic assets without starting from scratch. Rather than costly full rewrites that waste existing business knowledge, we modernize applications iteratively. This "upcycling" philosophy embodies our commitment to digital sustainability, reducing technical debt and extending the lifecycle of existing investments.
We design robust, scalable custom software perfectly adapted to each client's unique processes, with a strong focus on societal impact. Our 130+ committed professionals co-construct solutions through agile collaboration, transparent communication, and continuous improvement. With deep expertise in highly regulated sectors and a culture built on inclusion, work-life balance, and professional development, we create meaningful technology solutions that put people first while driving measurable organizational impact.
