Augmented financial management

The expertise of a CFO, the speed of AI′

Artificial intelligence and automation produce the figures faster and more reliably. The time saved goes to what matters: analysis, decisions and dialogue with your governing bodies.

Your data stays protected

No personal data in a general-purpose tool, tools governed by contract, an AI usage charter provided to every client.

Automated reporting

Dashboards update from accounting exports, with no re-entry.

Cash every week

The 13-week forecast is updated automatically; variances are flagged.

Systematic controls

Reconciliations and consistency checks run at every close, not just at year-end.

Summaries for governing bodies

Board papers are prepared faster; the analysis and recommendations remain the CFO’s.
