Work

What I’m building

A software company for institutions that need to change, the engineering practice that carries the work through, and the record behind them.

Current ventures

Threadneedle HQ 

Founder · 2025–

Software for understanding and changing complex enterprise systems, retaining the knowledge and evidence each change produces.

Strategy depends on the capacity of the underlying institution to change. Threadneedle is built to retain and extend that capacity across successive transformations.

Holborn Mercer 

Founder & Principal

A senior engineering practice that takes responsibility for enterprise platforms, from architecture through delivery.

The people who understand the business problem stay close to the system being built. A team assembled around the platform carries architecture, product judgement and delivery together.
