About

The rigour of a top-tier firm, without the overhead.

I build the financial models, valuations, and investor materials behind capital and strategic decisions – for founders, funds, and growing companies across industries. Most recently I delivered executive-facing strategy and modelling at Strategy&.

What clients get is senior, decision-grade work, delivered directly and quickly: the technical precision of the CFA Program, a legal background most modellers don't have, and the judgment to know which number actually moves the decision.
