How it works

Make EU regulatory change less painful

David Wormley has helped many organisations to design, implement, operationalise, update and improve policies, procedures and controls in response to changes in EU regulation, including:
  • MiFID
  • AIFMD
  • AMLD/AMLR

He has used this experience to build some extra workflows on top of this tool to feed its structured diffs directly into LLMs, to create context-aware and prioritised change management task lists covering policies, systems and controls.
