About TwinMind

Meet the minds behind TwinMind.

We build the custom AI systems that the manual processes standard tools don't cover - across finance, operations and engineering. Founded by a CFO and a CTO with 20+ years each in finance and technology, we start where off-the-shelf software stops.

Who we are

A CFO and a CTO, building side by side

TwinMind is a two-founder studio - twin brothers born in Ukraine, both university-educated (Sergii's degree with honours), now at home in Brisbane. One of us has spent a career in finance - closing books, owning the numbers, answering to auditors. The other has spent it in engineering - shipping software, wrangling data, keeping systems running. We kept hitting the same wall from opposite sides: the work that mattered most was the work no tool would do.

So we build it. Every system we ship is designed by someone who has actually done the job it replaces - which is why it survives contact with a real month-end, a real warehouse, a real audit.

What we believe

Principles we build by

Not slogans - constraints. They decide what we ship, and what we refuse to.

🧩

We start where the software stops

The non-standard 20% off-the-shelf tools leave behind - odd formats, custom rollups, systems that were never meant to talk. That's the part we automate.

🔒

Audit-ready by design

Every figure traceable to its source, every action logged. "Why did this change, and who approved it?" is always answerable.

🤝

A human approves anything touching money

Automation does the work; a person makes the call. Nothing that moves money or goes to a regulator happens without sign-off.

🇦🇺

Hosted onshore in Australia

Your data stays in Australia, aligned with the Privacy Act. Built for local businesses, on local ground.

🗝️

You own the system

You own the code and the system we build - not a rented seat you lose the day you stop paying.

🎯

Scoped and quoted up front

No open-ended meters. We map the work in the Audit and hand you a costed, fixed-scope plan before a line is written.

How we work

Audit, build, run

A short, costed path from "this is painful" to "this runs itself."

1

Audit

We map your repetitive, manual work and find where AI actually pays off - then hand you a costed, fixed-scope plan. The audit fee is credited to your first build.

2

Build

We build the system around the tools you already run - no rip-and-replace - and prove it on your real data before anything goes live.

3

Run

It clears the routine itself and surfaces only the genuine exceptions for a person. You keep the code, the logs and the control.

Let's find the work worth automating.

Book an AI Opportunity Audit and we'll map your repetitive work and hand you a costed plan to automate it - audit-ready from day one.
