Service 01 · AI Systems & Intelligent Automation

AI that does real work inside real systems.

Specialised agents, document intelligence, process automation, knowledge systems and voice AI, engineered inside your Microsoft 365, Google Workspace or Azure environment and the platforms connected to it, with identity, permissions, approvals, audit and cost designed in from the start. Brisbane-based, working Australia-wide.

Our position

Most AI agencies understand prompt → LLM → Zapier. That works until the agent needs to read a SharePoint library or a shared drive under the right identity, respect a permission boundary, survive a tenant change or explain what it cost. We engineer that part.

AI interface vs AI architecture

The assistant is the visible part. The architecture is the work.

We don't bolt chatbots onto websites. When we build a public AI assistant, it operates against controlled knowledge, approved tools and defined business workflows. The conversation a visitor or a team member sees is only the interface.

Behind it sit identity, permissions, knowledge, models, APIs, specialist agents, workflow orchestration, approvals, audit, observability and cost controls. That is what lets a public assistant capture a lead safely, or an internal assistant file a document, without a public model ever holding unrestricted access to a CRM, a mailbox or a tenant.

Public-facing assistants are covered in Intelligent Web Platforms. Internal, operations-facing assistants are what the capabilities below describe.

01 · AI agents

Agents with a job description, a scope and a supervisor.

An agent is only useful when it can act in your systems safely. We build agents against a defined identity, a defined set of permissions and a defined approval boundary.

  • Specialised business agents scoped to one process
  • Internal assistants over your documents and mail
  • Research agents that maintain reference information on a schedule
  • Operational agents that prepare work for people
  • Customer-facing agents with clear escalation to a person
  • Human-in-the-loop agents with approval gates enforced in code

Agents are orchestrated rather than left to roam. A routing layer sends each request to the agent, document workflow or model best suited to it, and the console shows what each one did.

In productionMia coordinates inbox, filing, contract, lender and reporting agents for The Mortgage Panel, with the broker approving anything consequential. Read the case study.
02 · Document intelligence

Documents understood by their content, not their filename.

Identity documents, statements, contracts, correspondence and forms arrive out of order and badly named. Document intelligence turns them into classified, extracted, validated records in the right place.

  • Document classification from content
  • OCR for scanned and photographed documents
  • Information extraction into structured metadata
  • Document validation against rules and expected values
  • Routing to the correct client, matter, deal or library
  • Summarisation for human review
  • Duplicate detection
  • Compliance workflows with an audit trail

Bulk migrations of existing libraries follow the same pipeline as new documents, so a backlog of years can be brought to one naming and filing standard and then kept there.

In productionApproximately 24,000 files were migrated and reclassified for The Mortgage Panel, a Brisbane brokerage using a deal-anchored naming convention. How the pipeline works.
03 · Business process automation

Remove the repetitive work between your systems.

Automation is an integration problem first. We map the process, choose the right tool for each step and build it so that it can be monitored and changed.

  • Workflow discovery and process mapping
  • API orchestration across vendors and internal systems
  • System integration through Microsoft Graph, Google Workspace, Slack, HubSpot, Salesforce, Xero and other vendor APIs
  • Approval workflows with named approvers
  • Event-driven automation (arrivals, changes, deadlines)
  • Power Automate where it fits the tenant
  • Apps Script and Google Workspace APIs where the work lives in Workspace
  • n8n for orchestration where a workflow engine is the right tool
  • Custom automation in code where the logic needs to be tested and versioned
  • MCP servers so agents can use tools with defined scopes

We are deliberate about tool choice. Low-code is used where it is maintainable, and code is used where it is not.

04 · Knowledge systems

Answers grounded in your own documents and records.

Retrieval over the systems you already have, respecting the permissions that already exist.

  • Microsoft 365, SharePoint and OneDrive
  • Google Workspace, Drive and Gmail
  • Slack, Teams, Notion and Confluence content
  • Internal documentation and procedures
  • CRM and line-of-business records
  • Databases and structured data
  • Knowledge retrieval with citations
  • Enterprise search across sources

Knowledge systems are permission-aware. A person, or an agent acting for them, only retrieves what they are entitled to see.

05 · Voice AI

Voice that qualifies, schedules and hands over.

Voice interfaces are useful when they are connected to the same operations layer as everything else and know when to stop and hand off.

  • Inbound enquiry handling
  • Qualification against your criteria
  • Scheduling into real calendars
  • Client servicing for routine requests
  • Internal voice interaction with the operations assistant
  • Recording, disclosure and hand-off rules designed in
06 · AI architecture & governance

The part most AI projects skip.

How the system is allowed to behave, who it acts as, what it can reach, what it costs and how you would know if it went wrong.

  • Model selection per task and the ability to swap
  • Identity: scoped application registrations, not shared accounts
  • Access control and least-privilege Graph permissions
  • Data boundaries, documented data flows and third-party processing
  • Human approvals enforced in workflow code
  • Monitoring and observability of tasks, queues and errors
  • Cost tracking per task and per day
  • Audit of every decision and approval
  • AI governance policies your board can read

See the ten principles we build to on the guardrails section of the homepage.

Bespoke by design

Your AI. Designed around your business.

Mia is one client's assistant, with a name, voice and interfaces chosen by that practice. Every Sigma Labs deployment is shaped around the organisation it serves. What stays constant is the engineering underneath.

Yours

The name is yours.

  • Name and identity
  • Voice and tone
  • Interfaces: portal, messaging, voice
  • Permissions and data boundaries
  • Specialist agents and workflows
  • Connected business systems
Sigma Labs

The architecture is Sigma Labs.

  • AI architecture and model selection
  • Agent orchestration
  • Integrations, APIs and MCP connectivity
  • Identity and security boundaries
  • Human approval controls
  • Audit, cost and observability

Give it an identity. We engineer what sits behind it.

Platforms & integrations

Works with the platforms you already run.

Microsoft is where we go deepest. The same identity-first discipline applies to Google Workspace, Slack, your CRM, finance, support and practice systems, and anything that exposes an API, webhooks or an MCP server. If your team already runs on it, we build around it rather than asking you to move.

Not listed? If it has an API, a webhook or an MCP server, we can architect around it. Every integration runs under a scoped identity with the least permission the job needs, and data flows to any third-party platform are designed, documented and agreed with you first.

Questions

Straight answers about AI in your business.

The questions owners and operations managers ask before they let an AI system near their documents.

Does the AI send emails or file documents on its own?
No. Agents draft, classify, summarise and prepare. Anything consequential, such as sending to a client or filing to a client record, waits for a person to approve. Approval gates are enforced in the workflow code and visible on the operations console.
Where does our data go?
Systems are architected around your existing Microsoft 365 or Google Workspace environment and its security boundaries. Data flows and any third-party model processing are explicitly designed, documented and agreed with you before anything is built.
Which AI models do you use?
Models are selected per task on capability, cost and data terms, and the architecture lets them be swapped as those change. We do not build your business around a single vendor's model.
Will this replace our staff?
We do not make that claim. The systems we build return capacity to the team you already have by removing repetitive preparation work. People remain responsible for decisions.
How do we know what it is doing and costing?
Every engagement includes an operations console showing running tasks, agent activity, errors, completed work, approvals waiting on a person and approximate model cost.
