About

I’m Chance Kelch, co-founder and CEO of Flock Synthetics. We use AI agents to test web products from different user perspectives, helping teams find confusing flows and failures before customers encounter them.

I’ve spent much of my career working on the gap between how a system is supposed to work and what happens when people use it. Sometimes that meant a warehouse. Sometimes a payments platform. These days, it’s AI.

Experience

I started in logistics at Caterpillar, then spent a decade at Amazon before moving to StockX and Stripe. Along the way, I’ve led everything from large operations organizations to small machine-learning teams.

Amazon — I built teams and machine-learning systems to identify unsafe products, with 84% of removals happening before a customer reported a concern. I’m a co-inventor on U.S. Patent 10,223,353, which describes identifying safety concerns in customer reviews.

StockX — Buying a gift for my wife led to a conversation with the founder, and eventually a job leading supply-chain product and engineering. I proposed and launched Express Ship, cutting delivery time from more than nine days to three.

Stripe — I led global onboarding compliance and built a system that used language models to evaluate policy requirements. It replaced roughly 250 keyword rules and reduced manual reviews in that workflow by 82%.

Advising

I help founders and leadership teams decide what to build, where AI is useful, and what needs to change for a promising prototype to work in practice. That ranges from solo founders working through an idea to teams inside large companies.

Writing

I write about building products, making decisions, and the results that change my mind. The mistakes tend to make the better stories.
