AI agents we build and run every day.

How we build them

The same safe pattern, every time

Every agent follows one proven pattern, so each new one is faster to launch and easier to trust.

  1. Step 1

    Someone asks a question

  2. Step 2

    A router works out what it is about

  3. Step 3

    Approved knowledge and persona rules are applied

  4. Step 4

    The AI drafts an answer

  5. Step 5

    Guardrails check it: send, or hand over to a human

Scoped

Each agent only answers within its topic. Everything else is declined or escalated.

Grounded

Answers come from material you approve, not the open internet. Agents that search the news cite the source and date.

Human in the loop

Sensitive topics go to a person, and every chat is logged so a human can review and improve answers.

Your data stays separate

Each agent has its own database. Nothing is shared across clients or products.

Monitored

Agents run under supervision with automatic restart, and our team is alerted if anything fails.

Behind every agent

Private servers, encrypted public access, a separate database per agent, job queues for reliable delivery, and automation workflows for images, video, email and alerts.
