About
A different kind of PPC consultancy - built on code, data, and a decade of e-commerce experience.
Cory Lindholm
Founder & Principal Consultant
I started writing Google Ads scripts before most agencies knew they existed. Nine years of PPC, a low tolerance for “we'll optimize it next month,” and a habit of solving problems with code led me to build Cart Science.
I write Python and JavaScript for feed automation and bid management. I've managed Shopping and Amazon campaigns for B2B distributors, large catalog retailers, and DTC brands - always gravitating toward the accounts where spreadsheets break and standard playbooks fail.
When I'm not in Google or Amazon Ads, I'm probably traveling, gaming, or watching basketball.
Why I Built Cart Science
Most agencies sell strategy decks and monthly reports. When the account has 50,000 SKUs, margin data that matters, and inventory that changes daily, they scramble. The technical work - feed optimization, custom bidding logic, inventory sync - gets deprioritized or handed off to someone who doesn't understand the business.
I got tired of watching that happen. Cart Science exists for the e-commerce businesses that need someone who can actually build the solution, not just recommend one.
