Private AI Infrastructure
Own and control your AI with our custom hardware and self-hosting expertise
ARBI Whitebox
ARBI Whitebox is our custom-built all-in-one AI device providing security, speed, customisability, and portability, allowing firms of any size to harness the power of AI while keeping their sensitive data within a secure perimeter.
The perfect AI sandbox for pilot deployments, offline environments and AI development.
Data Isolation
A dedicated deployment provides complete isolation and control over your sensitive data and AI operations.
Efficiency
An ultra-portable and virtually silent AI server that is powerful enough to support concurrent usage and process large volumes of information.
Customisability
Fine-tune open-source models on your specific tasks and integrate third-party tools for optimal performance on what matters to you.
London Data Centre
Unlike most AI service providers, we build and operate our own server infrastructure.
Our purpose-built AI computing cluster is powered by modern NVIDIA GPUs housed inside a secure data centre in central London.
Security & Compliance
Data centre certified to ISO 27001, ISO 9001, ISO 14001, ISO 45001 and PCI-DSS for security, quality, environment and safety.
European Infrastructure
Allows us to deploy low-cost private services in Europe without dependence on US-based cloud service providers.
Self-Hosting Support
Many forward-thinking firms are beginning to recognise the benefits afforded by fully self-hosted AI solutions, such as greater control, compliance, auditability and security.
Self-hosting requires specialised hardware and expertise, which is exactly where ARBI CITY can help, putting firms on the path to owning their AI and reducing reliance on third party vendors.

About Us
Where Legal Meets Digital
We are on a mission to empower legal professionals with the latest technology for productivity and collaboration.
Our Values
Legal Community Focus
Our company was created by and for legal professionals. Many of our investors and other stakeholders are lawyers, and we are committed to sharing free tools and resources through ARBI.CITY, the community platform for dispute professionals around the world.
We believe AI tools should amplify, not replace, professional craftsmanship, and that the technology should be accessible and affordable for all lawyers, regardless of where they work or their level of seniority.
Privacy and Customisability
We focus on building solutions that do not require users to share confidential data with anyone, including us.
Our AI solutions give users granular control over sharing information with collaborators, and we offer self-hosting options that allow businesses to deploy our tools within their own security perimeter and to customise them for their particular environment.
Our proprietary Whitebox is the ultimate private AI sandbox, a portable device that can even work in fully offline and air-gapped environments.
Transparency and Explainability
We are open about how our technology works, and offer tools that make it easy for legal professionals to trace and verify AI outputs. Our aim is to ensure explainability and auditability at every step, putting control in the hands of the user.
AI education is also central to our mission as it equips users with the knowledge and tools to use AI safely and effectively. We organise workshops, publish commentary, speak at events, and take part in industry task forces related to responsible use of AI in the legal sector.
