Built by the engineer who codes it
Stop losing hours to admin a machine could do in seconds.
We build AI that answers customers, writes quotes, chases invoices and moves data between your tools, 24/7. Founded by Lakitha Sahan, a software engineer with more than a decade of experience, delivered by a founder-led team: no account managers, no offshore teams. Fixed price, live in 2 to 4 weeks, on your servers or Australian-resident cloud.
We take on four new clients a month, scoped and built in-house by our engineering team.

The stuff we build
We don't sell vaporware. We build the agents, automations and software that take repetitive work off your plate, plugged into the tools you already use.
AI agents that answer 24/7
AI agents trained on your business handle customer questions, internal queries and data lookups around the clock. They answer like you would, because they're trained on your data.
Automation that kills the admin
We connect your tools and automate the repetitive work: quoting, invoicing, follow-ups, scheduling, reporting, and syncing data between apps so it stops living in copy-paste.
Content and marketing on autopilot
An automated content engine and marketing-automation packs that publish, run campaigns and chase follow-ups for you, built on DivertPro.
Low-turnaround MVP builds
Need the software itself, not just the automation? We ship working MVP builds in under two weeks, so you can put a real product in front of customers fast.
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 build your automations and AI agents, 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. 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.
I'm not a sales guy who outsources the work. I'm the person who builds your 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.
