Zaizi

Zaizi is an open source consultancy founded in 2007 that works with UK government agencies on technology and digital transformation. The firm's technical work spans open source technologies, digital service delivery, legacy system modernisation, AI readiness and the building of secure, user-centred services. Its client base sits across government and the wider public sector, including border security and national security, as well as general public services.

The company operates solely in the United Kingdom and states a mission to make the UK the best and safest place to live and work. Delivery is structured so that senior expertise remains close to client projects rather than being removed from them.

Internally, Zaizi organises itself through a 'Team of Teams' structure built around groups it calls Clubs, and describes its working culture as flat and collaborative. The firm frames its approach under a 'Realising Potential Together' philosophy covering client relationships, team growth and societal impact, with an emphasis on developing its own staff alongside a stated commitment to open source.
