About Zatersio
Zatersio is a founder-led AI automation consultancy for Australian businesses. It is run by Lakitha Sahan, a software engineer with around ten years of experience. The person who scopes your project is the person who builds it and the person who answers your emails. No account managers, no offshore teams, no hand-offs to people who were not in the room when the work was agreed.
Book your free auditWhy Zatersio exists
Most small and medium Australian businesses are quietly losing hours every week to work a computer should be doing: re-keying the same data, chasing quotes and follow-ups, answering the same questions over and over. The tools to fix this exist, but the usual options are either a big consultancy that bills like one, or an offshore shop that ships something you cannot maintain and cannot get support on.
Zatersio was built to be the third option: an engineer who will sit with you, work out where the time actually goes, and build something that pays for itself. We show real hours and real dollars, we price in Australian dollars including GST, and we tell you honestly when an idea is not worth automating.
What Zatersio does
AI agents
Custom AI agents that handle real work end to end: reading enquiries, drafting responses, updating your systems, and escalating to you only when a human is genuinely needed.
Workflow automation
Quoting, invoicing, follow-ups, data entry and reporting, automated and wired into the tools you already run. See our automation services.
AI receptionist
An AI receptionist that answers, qualifies and books, so you stop losing leads to missed calls and after-hours enquiries.
Most engagements land between $2,000 and $15,000 AUD (inc. GST) depending on scope. Not sure where to start? A free audit maps the highest-value automations for your business before you commit a cent.
Who we serve
We work with small and medium Australian businesses across a range of sectors, from trades and accounting to healthcare, law firms and real estate. Melbourne is home base, but we deliver across Sydney, Brisbane, Perth, Adelaide and Australia-wide and globally.
For regulated work in particular, the deciding factor is often control of data, which is where our Australian data sovereignty approach matters most.
The details that make us accountable
Australian-owned and registered
Zatersio is an Australian-owned business, ABN 48 668 612 020. You can verify us on the public register before you hire us.
A real Melbourne base
We are based at 1 Redwood Dr, Notting Hill VIC 3168. A real address, a real phone number on 0468 031 288, and a named person behind the work.
Engineer-led delivery
No account managers, no offshore teams. The software engineer who scopes your build is the one who writes the code and supports it afterwards.
Australian data sovereignty
Your data stays on infrastructure you control, in Australia, under Australian law, and is never used to train third-party models.
The person behind the work
Lakitha Sahan founded Zatersio after about ten years building software, because he kept seeing the same gap: capable businesses held back by manual work no one had ever got around to automating. He still does the engineering himself, which is the whole point.
About Zatersio FAQs
Zatersio is run by its founder, Lakitha Sahan, a software engineer with around ten years of experience. He is the person who scopes your project, builds it, and answers your emails. There are no account managers in between and no offshore teams touching your data. When you work with Zatersio you are working directly with the engineer doing the build.
We are based in Melbourne, at 1 Redwood Dr, Notting Hill VIC 3168. Being Australian-based and Australian-owned is central to how we work: it is how we keep your data under Australian law and how we stay accountable to the businesses we serve.
Yes. Melbourne is our home base, but we build AI agents and automation for businesses right across Australia, including Sydney, Brisbane, Perth and Adelaide, and we work with clients globally. Most of the delivery is done remotely, so where you are located is rarely a barrier.
Every AI agent we build runs on infrastructure you control: your own servers (on-premise) or Australian-resident cloud on the AWS Sydney region. Your data stays in Australia, under Australian law, and is never used to train third-party models. This makes it far easier to meet your obligations under the Privacy Act 1988 and the Australian Privacy Principles.
