I'm designing the payments and fraud systems ŌURA needs as we expand globally.

Building a global payments system is complicated, but there are strong public examples of how to do it. Airbnb's Pay as a local is one. What is not as well documented is a fraud system that still works across different markets. You cannot read yourself to one. Neither the fraudster nor the merchant wants to say how they actually work.

When a good customer looks like fraud
ŌURA. $59.6M GMV. 65.6% of flagged orders authorized.
The processor is not the source of truth
ŌURA. One money path behind D2C, B2B, and subscriptions.
A failed payment is not one event
Natural Cycles. −10% involuntary churn. +13.36% approval.

Before Natural Cycles I was at Heads (2021–2023), building retail POS software in React, Node, and iOS. Before that I founded iSpect and iControl, and helped found Buildcraft. Grew iSpect ERP to $4M ARR. Took iControl through 500 Startups Batch 19 ($150K seed) to $55K MRR. Built and led teams of up to 18 across four timezones. Offline-first sync from that decade is still in production.
