Agile Risk Consulting

Peter Horncastle, Fractional FD & CFO.


Interim finance leadership for businesses that need a finance lead without a full-time hire. Also publishes research and tools as Arkai-Optrix.

What I do See the research

How it's split

Two things, kept apart.

Agile Risk Consulting is the paid practice: interim FD and CFO work, sole trader. Arkai-Optrix sits alongside it as a separate, unpaid interest: data, research and programmes Peter builds and publishes because he finds it interesting, not client work.

Both are trading names of the same person, Peter Horncastle, kept clearly apart rather than blurred into one offer.
