Decision Makers: Deniz Ertan, eBay
A profile of eBay's Senior Director of Buyer Risk — and how a problem-solver from Turkey became one of the most thoughtful fraud leaders in the industry.

Deniz Ertan grew up in Turkey with a love for numbers and a knack for solving complex problems. What she didn't plan on was a green card lottery changing the trajectory of her life — prompting a cross-continental move with her husband and six-year-old daughter to build something new in the U.S.
This profile traces her path from consumer finance to leading buyer risk at one of the world's largest marketplaces — and explores how someone who thinks about fraud like a gardener thinks about her plants became one of the most thoughtful risk leaders in the industry. Patient, precise, and always watching for what's about to change.
The Decision Makers series was built on a simple idea: the people behind complex business decisions have stories worth telling. The goal was to move beyond the typical case study format and create something people would actually want to read. Less product pitch, more portrait.
