Zaizi

Zaizi is an open source consultancy founded in 2007 that works with UK government agencies, delivering secure, user-centred digital services. Its areas of work include open source technologies, digital transformation, legacy systems modernisation and AI readiness. The company describes its mission as making the UK the best and safest place to live and work.

The firm's clients sit across border security, national security and public services, and Zaizi is positioned as a trusted partner to the UK government. Projects centre on digital services for government bodies, spanning work on legacy systems and preparations for AI. Geographic presence is limited to the United Kingdom. No funding or headcount figures are disclosed; the company describes its origins as a small team that has since grown into a government supplier.

Zaizi operates under a philosophy it calls "Realising Potential Together", covering its relationships with clients, the development of its staff and wider societal impact. Internally it uses a structure it terms "Team of Teams", organised into groups called Clubs, with senior expertise kept close to client projects. The company retains a flat, collaborative culture from its early years and states a continuing passion for open source.
