ABOUT LUCIE BREINER
I’m a Product leader specializing in AI-driven pricing, marketplace economics, and commerce platform infrastructure. At The RealReal, I lead the strategy and execution of the core commerce platform powering a $2B+ luxury resale marketplace—spanning pricing, discounting, payments, catalog, and merchandising systems. My team builds the infrastructure and decisioning systems that determine how inventory is valued, priced, and sold across the marketplace. I focus on translating complex economic problems into scalable product platforms. This includes building machine learning–powered pricing systems trained on tens of millions of items and billions of buyer interactions, enabling automated valuation, dynamic discounting, and real-time market responsiveness. Some of the work I’ve led: Built and scaled AI pricing systems covering the majority of marketplace supply Launched the company’s first Lifecycle Discount Model (dynamic markdown system) Developed centralized pricing and discounting infrastructure optimizing manual workflows Led financial platform transformation to support audit-ready, scalable commerce systems Prior to The RealReal, I held product leadership roles at Wayfair, Alteryx, and Divvy Homes, focused on pricing optimization, growth, and platform transformation. I’m particularly interested in: AI-powered decisioning systems Marketplace supply/demand dynamics Building scalable product organizations and platforms
