AI agents with a human in the loop
Most of our AI work follows one pattern: the model drafts, your rules check, and a person steps in when it matters. This is how Sambung runs customer conversations.
Step 1: A customer writes in
A message arrives on WhatsApp.
Step 2: The agent drafts a reply
It answers from knowledge your team owns and keeps current.
Step 3: Rules check the draft
Topic, confidence and your policies decide what happens next.
Step 4: Routine answers go out
Anything sensitive or uncertain goes to a person instead.
Step 5: Your team takes over
An operator replies, then hands the chat back. Every step is logged.
Models and tools we build with
We pick the model per job and route through OpenRouter where it helps, so a product isn't tied to one provider.

Services
Each engagement starts with the work people need to do, then the right system around it.
The founder
I lead Immortech and stay hands-on in the engineering. Every project starts with how your team works today, and ends with a system people actually use: tested, documented and handed over properly.
