How we work
- Your data stays inside your boundary.
- Scope and price are written down before work starts.
- We say so when something is outside what we can do.
Where we work
Singapore and Malaysia.
A one-person firm, stated plainly
Maandoh is run by one person. For a regulated organisation that is a fair thing to examine, so this is how the engagement is set up to reduce the dependency:
- The system runs on your hardware and does not need Maandoh to keep operating.
- You receive written documentation and a handover so your team can run and review it.
- The regulation pack is delivered as files you keep.
- Scope, price and deliverables are fixed in writing before work starts.
Documentation and a handover session are included in every engagement.

No obligation. We will ask about your environment and tell you plainly whether we can help.
