We're builders who lead — and leaders who still build.
Stacksy is a Perth-based innovation and technology firm. We sit at the intersection of leadership, custom build, and AI — partnering with growing organisations of 1–300 staff to build software that fits how their team actually works.
Started by people who've shipped — repeatedly.
Stacksy was founded by leaders with two decades of experience building, scaling, and exiting technology businesses. Our founders have architected platforms that have served hundreds of thousands of users, led teams whose work has been recognised by national innovation awards, and reshaped entire industries — from cycling retail to sustainability to community sport.
That experience taught us one thing: strategy and build can't live in separate teams. The best outcomes happen when the people setting direction also understand the code, the cloud, and the constraints. So that's how we work — every engagement is led by people who can scope, design, and ship the solution end-to-end.
Founder-led. Senior-only.
No juniors hidden behind a partner's photo. The people you meet are the people who do the work.

Outcomes over outputs
We measure ourselves by what changes for your users — not how many slides we shipped.
Senior-only delivery
The people who scope your problem are the people who solve it. No bait-and-switch.
Responsible technology
We build with governance, reproducibility, and the people impacted by the system in mind.
Honest scoping
If we're not the right fit, we'll tell you. If something's a bad idea, we'll say so before you spend.
