What COMC does

COMC (Check Out My Collectibles), operating as Check Out My LLC, runs an online marketplace for buying and selling sports cards, trading cards, gaming cards, and comics. Founded in 2008 and headquartered in Redmond, Washington, the company manages over 100 million cards across approximately 200,000 square feet of distribution space, with nearly 300 employees as of November 2023. The platform lists 48 million+ total cards including 13.5 million unique sports cards, supported by high-resolution front-and-back scans of every listed card to enable remote condition assessment. Revenue is generated through marketplace commissions on seller transactions and through professional consignment services in which COMC identifies, scans, lists, stores, insures, packages, and ships cards on behalf of sellers for a service fee. A flagship feature is the "buy now, ship later" flat-rate shipping model that lets collectors consolidate purchases from multiple sellers into a single shipment, reducing friction for set builders and player collectors.

COMC's technical stack centers on a proprietary marketplace platform with patented underlying technology. Its most strategically significant asset is an AI-powered bulk listing computer-vision pipeline that processes uploaded card photos and auto-generates listing drafts — a capability licensed to eBay and deployed as eBay's AI-powered bulk listing experience for trading cards in July 2024. All COMC listings are automatically cross-posted to eBay under a commercial agreement that included an investment from eBay Inc. in November 2023. The platform also offers grading services (via CGC and CSG partnerships), mailbox storage, marquee auctions, port sales, and historical sales data for price discovery. Go-to-market is primarily self-serve and product-led, supported by organic social media, blog content, and email, with no disclosed enterprise sales motion.

The business model is marketplace commission plus full-service consignment, serving hobbyist collectors, card resellers, and gaming/entertainment card collectors globally. The company is private and does not disclose revenue. Recent signals in late 2025 — reported layoffs, deteriorating service quality, and Upper Deck's planned migration of e-Pack physical card fulfillment to a competitor starting January 2026 — introduce meaningful operational and partnership risk that offsets the positive trajectory implied by the eBay partnership and a sports card market projected to grow from $5B in 2023 to $12B by 2030.
