Our Story

Why we built SmartBuy

Every week, thousands of Costco members walk through those warehouse doors without knowing if today's price is a good deal or not. They guess. They buy too much or too little. They miss the 30-day price adjustment window. They never know which month is the best time to stock up.

SmartBuy was built to end the guesswork. Starting in early 2024, we've collected Costco promotional flyer and related promotion data — 30,000+ records across 131 weeks of continuous history, covering 10,000+ SKUs. That history tells you what no gut feeling can: exactly where today's price stands relative to everything Costco has offered in the past 2.5 years.

The service runs entirely on WhatsApp. No app to install. No account to manage. Just ask — and get a data-backed answer in seconds.

Kelly Yang

Co-founder, DoneEasy.ai · AI Product & Operations Manager

Kelly Yang is a seasoned IT engineer with extensive technology and management experience, and a co-founder of DoneEasy.ai and SmartBuy. She is committed to turning advanced AI capabilities into simple, reliable products and services that solve real problems, so everyday users can benefit without any technical background.

At SmartBuy, Kelly starts with the real shopping needs of Costco members, connecting technology, processes, and operations to turn complex historical pricing data into clear, practical, and trustworthy purchase recommendations.

"More than two decades at IBM taught me that truly valuable technology must do more than be advanced—it must be reliable, easy to use, and able to solve real-world problems. At SmartBuy, I want to turn complex data and AI into an everyday shopping companion that every Costco household can use and trust."

Co-founder

Kevin Ge

Co-founder, DoneEasy.ai · AI Solutions Architect

Kevin Ge is an engineer focused on delivering AI solutions for individuals and small businesses. He founded DoneEasy.ai with one mission: to make powerful AI tools truly accessible to everyday people, with no technical background required.

As a Costco member himself, Kevin got tired of wondering whether a price was actually good. So he built SmartBuy: a system that ingests 131 weeks of real Costco data and turns it into clear, actionable advice — delivered through WhatsApp, the tool everyone already uses.

"The best technology is the kind you don't have to think about. You just use it, and your life gets a little easier. That's what I'm building."
