We design operating systems for teams that deliver.

Urgent work starves strategy. We give teams AI agents they can trust.

Led by Andy Woolterton — two decades in enterprise architecture and AI strategy. Building governed agent systems for insurance and professional services.

Proof in the real world

After-Image · Creative venture

Built a luxury photography brand from zero using NullProof's own framework. Multi-Clock Work handled strategy, governance, and back-office operations — freeing the founder to focus on client-facing creative work. Live, taking commissions.

Proves: governed creative operations at commercial scale.

Portfolio Exposure Radar · Insurance

Continuous intelligence for emerging risk. 13 source workflows monitoring regulatory, litigation, scientific, and market signals. Cross-referenced against client portfolios with automated scoring and agent-driven escalation.

Proves: insurance-grade signal monitoring under governance.

NullProof Studio · Internal pilot

Built the operating system that runs this studio. One human, governed AI agents, ninety days from zero to production. Live, taking commissions.

Proves: the studio runs on its own platform.

What we build

Governed agent systems

AI agents that operate under explicit trust boundaries. Durable event queues, belief graphs, hallucination detection, three-stage validation with supervisor arbitration. The governance isn't bolted on — it's the architecture.

Insurance & risk infrastructure

Signal monitoring across regulatory, litigation, scientific, and market sources. Claims processing with FNOL routing. Portfolio exposure scoring. Built for brokers and underwriters who need to know what changed overnight.

Open-source tooling

en-quire: an MCP server for governed markdown and YAML editing. Section-level addressing, RBAC, git-native approval workflows, full-text search. Works in any language. On npm and Docker Hub.

Beyond Pillars: How Frameworks Become an Operating System

Important work ages in the background while urgent noise fills every hour. To stop this, organisations must move beyond static frameworks—the 'pillars'—and adopt a kinetic operating system that governs how work is filtered, orchestrated, and dispatched across a hybrid workforce of humans and autonomous agents.

The Identity Gap: Agent Security's Missing Layer

Published agentic AI stack architectures — five-layer, seven-layer, and nine-layer frameworks in common circulation, alongside Microsoft's own agentic AI roadmap reviewed as of April 2026 — cover compute, models, orchestration, tooling, and observability. None include trust as a named layer. Agents can hold wallets, execute payments, and submit documents - they just can't prove who they are. This paper examines why the identity layer is missing from agent runtimes, how existing standards (W3C DIDs, Verifiable Credentials) can fill the gap, and why the window to build it openly is now.

Trust Management for Agent Operations

Every governance framework in use today embeds trust assumptions calibrated on decades of human behaviour. Agents break those assumptions. This paper argues that trust management - the explicit identification, assessment, and governance of trust signals - needs to become a discipline in its own right, with registers, scoring, thresholds, and continuous monitoring, paralleling how organisations already manage risk.

en-quire: Governed Markdown Editing for Agent Systems

Agents that manage documentation need more than file access — they need structure, governance, and the ability to edit precisely without reading everything. en-quire gives them that: section-level editing, searchable document structure, and git-native approval workflows, all without imposing a schema on your markdown.
