About Proofmarc

The infrastructure layer for
defensible AI decisions.

Proofmarc was built because the question regulators, boards, and customers will ask of every automated decision over the next decade is the same one: show me how this was decided. We give regulated entities a permanent, structured answer.

Why we started

By 2025, every major Australian bank, insurer, and superannuation fund had production AI inside customer-facing decisions: credit, claims, fraud, eligibility, suitability, complaints triage. By 2026, regulators were asking those same firms how they evidence the decisions their models make.

Most firms don't have a clean answer. The model output is logged. The customer outcome is logged. The connection between the two, the human review record, the model version, the confidence score — that lives in tickets, in Slack, in someone's head. When APRA or ASIC ask, the firm has to reconstruct it.

Proofmarc closes that gap. We sit beside any model, any provider, any in-house system, and capture the structured record before the trail goes cold.

What we believe

PRINCIPLE 01
Auditability is infrastructure
Decision evidence should not be a quarterly reporting project. It is a runtime obligation, captured at the moment the decision is made.
PRINCIPLE 02
Model-agnostic by design
The audit layer cannot lock you into a model provider. We log the decision, not the weights, so you can swap providers without losing your governance posture.
PRINCIPLE 03
Boards deserve readable evidence
If a director cannot understand the report in under five minutes, the report has failed. Our default output is the board pack, not the data dump.

The shape of the company

Proofmarc is built and operated by Thinx AI Pty Ltd, an Australian-incorporated company headquartered in Melbourne. We are designed to remain Australian-domiciled. Customer data is processed only in AWS Sydney. We do not co-train on customer decision records.
