Tailored Products for Regulated IndustriesBetter products, lower cost and trusted local expertise.

The solution

Your products or our products.

Launch on our platforms, or hand us custodianship of yours. Either path runs off TSG Attest, our purpose-built compliance platform, so cost comes down, flexibility goes up, and governance never stops.

Why us

Continuous governance.

Compliance evidence writes itself as your team works. Built on three decades of enterprise advisory, TSG Attest continuously captures what your systems do and maps that activity to the regulatory frameworks that matter — APRA, ASIC, ISO, PCI DSS, and beyond. Compliance isn't retrofitted after the fact — it's embedded from day one, and that's how software earns trust.

TSG Attest Governance Control Plane: showing 13,464 tests passing, evidence pillars, and continuous monitoring across regulatory frameworks
How we work

Proving high touch tailored delivery is scalable.

We don't deploy platforms and disappear. Every TSG engagement combines AI-augmented engineering, managed operations, and ongoing stewardship, operating as a trusted partner within your compliance and governance environment.

I want the red one!

AI Is Approaching Its Proxy-Server Moment

We Built a CRM. The Bond Market Will Finish the Job.

Software that once required an enterprise licence can now be built in-house, and the productivity gain lands in the customer's business rather than the vendor's revenue. Why the AI investment boom may succeed technologically and still disappoint the people funding it.

The Only Difference Is That One of Them Is New

Two banks write the same $500,000 loan against the same house, under the same prudential framework. One holds $9,592 of equity against it. The other, authorised last month, holds $23,760.

Why This Company. Why Now.

AI has collapsed the economics of creation, but not the economics of understanding. As systems become more autonomous, the real challenge shifts from building faster to remaining trustworthy, governable and accountable.
