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. Built personally by one engineer with 10 years' experience: 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 by one engineer.

You Choose Where Data Lives

The real question isn't what automation costs.
It's what doing nothing costs.

The stuff we automate

We don't sell vaporware. We build real automations that plug into your existing tools and start saving you time from week one.

Answer customers 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.

Kill the repetitive admin

We connect your tools and automate the repetitive work: quoting, invoicing, follow-ups, scheduling, reporting. If you do it manually every week, we can probably automate it.

Stop re-typing data between apps

We sync your systems and clean your data so it stops living in copy-paste: Xero to CRM, Shopify to warehouse, forms to invoicing.

Three steps. That's it.

No 6-month discovery phases. No endless meetings. We move fast and build things that work.

01

Audit

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.

02

Build

We design and build your automations and AI agents, connected to your existing tools, tested with real data, and ready to go.

03

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.

Don't see your industry? Doesn't matter. If you've got repetitive tasks, we can automate them. Book your free audit and we'll show you what's possible.

Built by an engineer who's spent 10 years watching businesses do things the hard way.

After a decade as a software engineer, 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.

We're honest about what automation can and can't do
Deploy on your own servers or Australian-resident cloud (AWS Sydney), your choice, and never train third-party models on your data

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.
