Link Group

Link Group is a Polish technology services company founded in Warsaw in 2016 that builds and supplies engineering teams to clients across Europe. Its model combines body leasing and managed teams with delivery of complete software, cloud and cybersecurity projects, drawing on a large bench of contractors rather than a fixed permanent staff. The company works heavily in financial services, telecommunications and public sector projects, and has built a specialisation in blockchain and distributed ledger engineering alongside more conventional cloud and application development work.
