Engineer-led. Melbourne-built.
Your MVP, live in under two weeks. Up to 43.5% backif you're R&D eligible.
Zatersio is an engineer-led software team in Melbourne, founded by Lakitha Sahan, a software engineer with more than a decade of experience. We build MVPs structured for R&D Tax Incentive eligibility: we build the evidence trail, your accountant or R&D advisor confirms the claim. And once you're live, our voice agents, automation and content engine run the busywork. Fixed quotes, no offshore handoffs, on your servers or Australian-resident cloud.
We take on a limited number of new builds each month, scoped and built in-house by our engineering team in Melbourne.

We build your product first
Your MVP is the main event: working software in under two weeks, built so eligible companies can claim the R&D Tax Incentive. Once you're live, the same team runs the busywork around it.
MVP builds, live in under two weeks
We turn your idea into working software fast, engineered and documented so eligible companies can claim the R&D Tax Incentive. You own the code and the IP.
And once you launch, we run the rest
Voice agents that never miss a call
Custom AI voice agents answer, qualify and book your inbound calls, and make outbound follow-ups and reminders, 24/7.
Automation that kills the admin
Built on DivertPro, our in-house platform, or the tools you already run: we automate the repetitive work: quoting, invoicing, follow-ups and data sync.
Marketing content, handled
Our in-house content engine, Goblin, generates, manages and publishes your marketing content. We run it, you approve it.
Three steps. That's it.
No 6-month discovery phases. No endless meetings. We move fast and build things that work.
Discovery
On a free discovery call we look at how your business runs day-to-day, find the repetitive bottlenecks, and figure out what to automate first for the biggest impact.
Build
We design and ship your build (an automation or an MVP), connected to your existing tools, tested with real data, and ready to go.
Launch & Optimise
We get everything live, train your team, and stick around to make sure it's running smoothly. Then we optimise based on real results.
Industries we know
We work best with businesses where repetitive admin is eating into the time you could spend on actual revenue-generating work.
Trades & Construction
An AI voice receptionist trained on Aussie tradie jargon answers, quotes and chases for you, 24/7, booking straight into ServiceM8, Tradify, AroFlo or Fergus.
Professional Services
Accounting, financial planning, mortgage and insurance broking, law and recruitment: Zatersio owns the inbox, drafts to your precedents and chases the docs. On-prem or AWS Sydney for privacy compliance.
Don't see your industry? Doesn't matter. If you've got repetitive tasks, we can automate them, and we build full MVPs for companies creating something new. Book your discovery call and we'll show you what's possible.
Built by an engineer who's spent more than a decade watching businesses do things the hard way.
Zatersio was founded by Lakitha Sahan, a software engineer with more than a decade of experience. After those years building software, and years of consulting on the side, I kept seeing the same problem: smart business owners buried in admin that a machine could handle in seconds. Data entry, follow-ups, quoting, reporting: all of it eating into time that should be spent growing the business. These days the same team also ships full MVPs for companies building something new.
I'm not a sales guy who outsources the work. I lead the team that builds your software and automations, and I stick around to make sure they actually work. No account managers, no offshore handoffs.
Your data, on your terms. Your servers or AWS Sydney.
Most automation tools send your business data through US-owned servers. That means your customer info, your quotes, your emails, and your internal data could be subject to foreign laws. We give you the choice instead.
Essential if you're in healthcare, legal, finance or government, optional for trades and retail, where it's a nice-to-have rather than a must.
On your own servers
Run the full stack on-premise, inside your own network. Nothing leaves your building.
Australian-resident cloud
Or host on Australian-resident cloud (AWS Sydney). Your data stays onshore.
Either way, your data is never used to train third-party models.
Who needs this
- Healthcare and medical practices handling patient data
- Financial services and accounting firms
- Legal practices with client confidentiality obligations
- Any business with government contracts or compliance obligations
- Anyone who just doesn't want their data on someone else's servers
You own everything. If we part ways, your automations keep running, with full compliance with the Privacy Act 1988 and the Australian Privacy Principles.

Frequently asked questions
Most automation and AI agent projects take 2 to 4 weeks from kickoff to live. Simple integrations can be faster. We agree on scope and timeline before any work starts.
Xero, MYOB, Shopify, HubSpot, Google Workspace, Microsoft 365, Airtable, Slack, Zapier, Make, n8n, and most other SaaS tools with an API. If you're not sure, ask us.
No. We build automations that run without technical oversight. We also provide documentation and a handover session so your team understands what was built.
Yes. Run it on your own servers or on Australian-resident cloud (AWS Sydney), your choice, and your data is never used to train third-party models. For cloud builds we only connect tools you already use.
Automation and AI agent projects land between $2,000 and $15,000 AUD as a one-time build fee. There's no ongoing retainer unless you want one. We quote fixed prices, no hourly billing surprises. MVP builds are scoped per project with a fixed quote after a discovery call.
Both. We build working MVPs in under two weeks for companies that need the software itself, structured so eligible companies can claim the R&D Tax Incentive. Automation, voice agents and our managed content engine cover everything after launch.
Eligible companies with under $20 million aggregated turnover can claim a 43.5% refundable tax offset on eligible R&D expenditure. AusIndustry and the ATO decide eligibility, and your accountant or registered R&D advisor confirms the claim. We build the technical evidence trail that supports it. This is general information, not tax advice.
Yes, optionally. After handover, we offer maintenance packages for businesses that want someone on call. These are month-to-month with no lock-in.
