About

I build and run enterprise AI in regulated financial services: the operating model, the governance, and the production systems that let senior leadership rely on AI inside real decisions.

Over the past decade at DNB Carnegie I built the Investment Banking Division’s AI and data capability from nothing. It is now a governed platform of more than ten production applications across origination, execution, debt advisory and coverage, built on proprietary data and used daily by a front office of 300+ bankers and analysts across the Nordics, the UK, the US and Singapore. The result senior leadership cares about is operating leverage: the division grew revenue substantially faster than headcount over the period, because the capability went into live workflows instead of into more people.

Most AI programmes underestimate what comes after the model. My work is the part that makes output defensible enough for a banker, an analyst, or a compliance reviewer to act on, and reliable enough to carry into public media communication. It also keeps the capability running through post-merger integration and successive leadership changes. That means governance, reliability, vendor selection, and the engineering discipline that separates a demo from a system people trust.

My current focus is the move from standalone tools to an AI operating model: agentic systems embedded in live workflows, built on proprietary data, with enterprise-grade governance. I also publish on the measurement problem. My Capital Markets LLM Reliability Score sets out how far LLM output can be trusted in regulated financial workflows.

Selected Proof

  • From zero to production

    Built DNB Carnegie's Investment Banking Division AI and data capability from nothing over a decade.

  • Operating leverage

    Revenue grew substantially faster than headcount as AI moved into live workflows.

  • Platform at scale

    10+ governed production applications on proprietary data, used daily by a 300+ front office across the Nordics, the UK, the US and Singapore.

  • Governance & reliability

    Output built to a banker's and compliance reviewer's defensibility bar, and reliable enough to carry into public media communication; the capability held through post-merger integration and leadership change.

  • Vendor selection

    Evaluated around 15 AI and data vendors over five years and set institutional adoption decisions.

  • Published research

Research & Writing

Selected work on making AI output reliable enough to act on in regulated financial workflows.

Capital Markets LLM Reliability Score (CM-LRS): From Plausible to Bankable

A seven-dimension reliability metric for LLM output in capital-markets workflows. Demonstrated across five workflows and four models, scored by four independent LLM judges from three model families, with a deterministic verification script (95 checks, all passing).

A notable result: two frontier models were statistically indistinguishable on reliability despite a material cost difference, which argues for choosing models on workflow fit and cost rather than headline quality.

The Checking Problem: What Must Be True Before AI Ships in a Regulated Firm

A controlled study of why enterprise AI programmes stall. Six document-heavy workflows of the kind performed daily in regulated financial services, run across four model families and three tool configurations, three times each: 5,093 scored output elements across 72 configurations. 57 cleared a demonstration bar; 32 cleared a production bar requiring sustained accuracy, reproducibility across repeats, verifiable attribution and a confidence signal that carries information. A survival rate of 56.1%.

A tool that states no confidence requires review of 100% of its output, because it offers a reviewer no basis for triage. Requiring it to cite sources and state a confidence reduces that to 49%. The value of an AI workflow is set less by how often it is right than by how much of it a human must still check.
