Independent advisory · Lausanne & Geneva

Transforming finance to steer the business, building systems to scale it.

I help CFOs and executives build a reliable finance and operations backbone, steer performance on top of it, and turn the resulting data into sound strategic decisions.

Dual finance & data expertise

An architecture aligned with strategy: I align the data model with operational processes and the way the business is steered.

From strategy to execution

Not just advisory: I design the target alongside stakeholders and see it through to implementation.
