Herfel Limited is built around a simple idea: complex systems become legible when we understand the mathematical, organisational and mental models that shape them.

We provide specialist consulting across internal audit, risk, treasury and model risk, while developing data analytics and AI tools to interrogate complexity, expose hidden dependencies and strengthen organisational resilience.

Herfel is also an independent publishing house, producing Modes of Money, technical papers and books on finance, uncertainty, human judgement and models.
