About
I've spent the last two decades building systems where trust is critical—payments, marketplaces, and platforms operating at global scale.
At Uber and Afterpay, that meant designing for fraud, risk, identity, and adversarial behavior before those patterns became mainstream.
Previously
Areas of investigation
An operational pressure field.
Modern systems are tightly coupled in ways institutions barely understand. Pressure moves quietly before failure becomes visible.
Most systems fail gradually before they fail visibly.
Synthetic behavior
How AI agents reshape trust assumptions.
Operational abuse
What breaks when adversaries scale faster than systems.
Organizational fragility
What companies remove when optimizing for efficiency.

David Katz
Former CPO of Afterpay, VP Product at YouTube
“A tremendous talent who drives complex products and earns trust across the organization.”
