Sovereign enterprise AI

AI Consulting Melbourne

Lexylon is a Melbourne AI consulting and enterprise software firm that designs and builds sovereign AI systems on Australian infrastructure, from private RAG and secure LLM architecture to autonomous agents and AI voice telephony.

Most AI consulting in Australia stops at a strategy deck. Lexylon is an engineering firm: the same senior architects who scope the work design the retrieval pipeline, wire the agent into your phone system, and keep it running in production. We work on-site across Melbourne and Victoria, remotely for organisations anywhere in Australia, and with international clients who want the same sovereign standard applied to their own jurisdiction.

Every engagement is built around one constraint that matters more here than anywhere else: your data stays in Australia, under Australian privacy law, on infrastructure you control. That is not a feature we add at the end. It is the first design decision.

The practice

Three disciplines, one AI engineering team

Enterprise RAG & Secure LLM Architecture

Private retrieval and generation over your own documents, on your own infrastructure. The foundation for copilots, search, and analysis that never send a record offshore.

Explore the practice

Autonomous Agents & AI Voice Telephony

Agents that do the work rather than describe it: answering real phone numbers, executing workflows, and escalating to a person with the full context.

Explore the practice

Strategic IT Consulting & 24/7 Enterprise Support

Fractional CTO leadership for the decisions around AI: which problems are worth it, what it will cost, and how it fits the systems you already run.

How it runs

From first conversation to production in 90 days

  1. 01

    Discovery, free of charge

    A senior engineer reads your systems, your data, and the problem you are trying to solve, then comes back with a proposed approach and costed options. No obligation, no deck.

  2. 02

    Design and pilot by Day 30

    Architecture, data residency, and security boundaries are decided on paper first. A working pilot runs in staging against your real data shapes within the first month.

  3. 03

    Production by Day 90, then supported

    The first workflow goes live behind a measured rollout, with 24/7 support already watching it. From there, delivery is a rhythm, not an event.

Read the full methodology

Data sovereignty

Frontier capability, Australian jurisdiction

Australian jurisdiction, always

Models, vector stores, and audio are deployed on-premise or in Australian cloud regions. Nothing about your data leaves the country to make the AI work.

Built to the Privacy Act

Retrieval is logged, personal information is minimised before it reaches a model, and every answer can be traced back to its source document.

Your existing systems stay

AI connects to the data you already have, including DB2 on IBM i, through typed APIs. No rip-and-replace, no second copy of the business in someone else's cloud.

FAQ

Questions Melbourne businesses ask about AI consulting

What does AI consulting with Lexylon involve?

It starts with a free discovery session where a senior engineer reads your systems and the problem you want solved. From there we design the architecture, run a pilot in staging within about a month, and take the first workflow to production with support in place. The people who scope the work are the people who build it.

Can our data stay in Australia?

Yes, and that is the default. Models, retrieval indexes, and voice audio run on your own infrastructure or in Australian cloud regions, under the Privacy Act and the Australian Privacy Principles. We do not send your records to overseas-hosted models.

Do we need to replace our existing systems to use AI?

No. Most of the value is in connecting AI to the data you already hold, whether that sits in a modern platform or in DB2 on an IBM i. We expose that data through secure APIs and build the AI capability beside your systems, not on top of a rewrite.

How long until a working AI pilot is running?

Typically within the first 30 days. Architecture and data boundaries are agreed first, then a pilot runs in staging against your real data. Production follows a measured rollout by around Day 90 for a first workflow.

What does AI consulting cost?

We do not publish rates. Work is priced under three models: a dedicated team, time and materials, or a fixed price per module built from an honest estimate of hours. The discovery session is free and ends with costed options you can question line by line.

Do you work with businesses outside Melbourne?

Yes. Lexylon is headquartered in Melbourne with on-site capability across Victoria and Sydney, works remotely with organisations anywhere in Australia, and takes on international clients who want the same data-residency discipline applied under their own laws. Smaller and mid-size businesses are welcome; what matters is a real problem worth solving.
