DF4: The AI Lab for the Builder Economy
DF4 is an AI Lab building MAIOS, a sovereign multi-agent intellgent operating system that runs inside organisations and powers secure, persistent, explainable AI workflows. MAIOS is engineered using safety-critical software principles developed from our experience building autonomous vehicle systems.
We combine MAIOS with the FoxLit developer suite to give teams the tools to build production-ready applications, internal AI agents, and automated workflows — entirely on-premise, with full data control and no external dependencies.

With DF4, every organisation can deploy its own private AI system — trained on its data, running on its hardware, and operating as an internal AI workforce.
We develop sovereign multi-agent AI systems, automation platforms, and next-generation tools that help founders, enterprises, and governments build faster, operate smarter, and embrace AI safely.

We Build Intelligence-as-Infrastructure
DF4 transforms organisations by deploying multi-agent AI systems that integrate seamlessly with internal processes, tools, data and workflows.
Our work spans three core pillars:
MAIOS — The Multi-Agent Operating System
MAIOS is DF4’s sovereign OS for enterprise AI. It provides:
- persistent memory
- long-context reasoning
- multi-agent orchestration
- structured RAG over internal systems
- tool and API execution
- explainability and audit trails
- company-specific skill libraries
- safe, governed agent behaviour
- full on-prem deployment (cloud optional)
MAIOS enables businesses to build internal AI capability — not rent AI from the cloud.
Deploy your own AI system → Trained on your knowledge → Under your governance.
FoxLit Developer Suite
FoxLitX — App Builder
Build production-ready applications in hours, not months — including UI, APIs, auth, dashboards, and data models. Built directly on MAIOS for reliability, security and auditability.
FoxLit CLI — Code Automation
For engineers who want full control. Scaffold, generate, deploy and refactor code using MAIOS-powered multi-agent workflows.
FoxLit CoPilot — AI Assistant for Engineers
A multi-agent developer companion for planning, debugging, integration, documentation, and QA — running privately within your infrastructure.
FoxLit turns MAIOS into a full-stack internal development engine.
AI Transformation & Automation
