Fei Wang

Fei Wang is the Co-Founder and CTO of Spangle, an AI company helping retailers acquire customers, improve shopping experiences, and grow sales as commerce moves into AI.

Before founding Spangle, Fei spent 12 years at Amazon, becoming a Principal Engineer. He was a founding engineer on the Alexa team and the founding architect of Amazon’s customer support agent chatbot. His work focused on building conversational AI systems that could understand customer intent and help solve real problems at scale.

He later served as CTO of Saks OFF 5TH, bringing firsthand experience with the challenges of enterprise retail.

That combination of experience shaped how he approaches AI. Understanding what a customer wants is only part of the challenge. For AI to be useful in commerce, it also needs to understand the retailer’s products, priorities, and business context.

At Spangle, Fei leads the development of AI systems that bring those capabilities together, helping retailers understand customer demand, make better decisions, and act on opportunities as shopping moves into AI.
