About CartHappy
CartHappy was built on a simple belief: access to the right data can change the way people live and spend. Our founders, John and Josh, first proved this with ADstruc, a platform that brought transparency to out-of-home advertising by making opaque pricing and audience data accessible and actionable.
Years later, a moment in a grocery aisle — comparing cereal prices across two stores a few miles apart — made the gap obvious. The same item can cost noticeably different amounts a few miles apart, and those prices move week to week. In a market defined by rising prices and constant volatility, families were left doing the math by hand, or not doing it at all.
CartHappy closes that gap. It works across every store you shop instead of living inside any one of them, so for the first time the full picture is in one place — every price, every coupon, every week.
Real Technology
We process more than 350 million grocery prices a day through our own data engine, matching items across retailers at the SKU and UPC level so a comparison actually means something. No manual lists, no receipt scanning, no guesswork.
Real Intelligence
We track what a product costs at every store near you and how that price moves, then check your cart against all of it while you shop.
Coupons you qualify for get applied automatically. When something is cheaper down the road, you see it before you check out.
Shoppers who split a basket across more than one store save 18% on average.
Real Empowerment
CartHappy is a free Chrome extension. Setup is a zip code — every participating store near you is selected automatically, with no accounts to connect. Take the savings at online checkout, or email yourself the cart organized by store and shop it in person. Real money saved every week, without the stress or the mental math.
