CatchBack Cards, a startup building a digital platform for trading card collectors, has secured $500,000 in funding as it looks to bring greater liquidity, transparency, and accessibility to the rapidly growing collectibles market. The company, founded in 2025 by Joseph Zhang and Sophia Kim, is part of the Winter 2026 batch of Y Combinator, which participated in the funding round with its standard investment package.

The Wilmington, Delaware-headquartered company is focused on modernizing the trading card ecosystem, a market that spans Pokémon, sports cards, anime collectibles, and other categories. CatchBack Cards operates an iOS and web-based platform where users can create custom mystery packs, open digital packs backed by physical cards, receive instant buyback offers, and trade cards through a low-fee marketplace.

According to company information and investor materials, CatchBack was launched to address several longstanding challenges facing collectors, including high transaction fees, illiquid secondary markets, and a lack of transparency in mystery pack offerings. The platform seeks to differentiate itself by providing cryptographically verified odds for mystery packs and allowing collectors to independently verify pack fairness through open-source card selection tools.

The startup’s founders bring experience from technology, consulting, and design backgrounds. Chief Executive Officer Joseph Zhang previously worked as a software engineer at Amazon Web Services and as a consultant at McKinsey, while co-founder Sophia Kim has experience in animation, product design, and user experience development.

CatchBack’s business model centers on increasing market efficiency for collectors. Users can purchase digital packs that correspond to physical cards stored in secure vaults, then choose whether to trade, sell, or request shipment of the cards. The platform also offers instant buyback options, enabling users to quickly convert collectibles into cash through integrated payment services. In addition, the company operates a marketplace that charges a flat transaction fee rather than the percentage-based fees commonly associated with larger online marketplaces.

The funding comes as the company reports early traction among collectors. CatchBack has stated that monthly gross merchandise volume from pack openings has increased significantly since its launch, while its user base has expanded into the thousands. The company has highlighted growing interest in digital-first collecting experiences that preserve the excitement of opening packs while providing greater transparency and flexibility for users.

Beyond buying and selling cards, CatchBack is developing additional financial features aimed at making collectibles more liquid assets. Company materials indicate plans that include collectible-backed lending and other services designed to help collectors unlock value from their collections without necessarily selling them outright. Such offerings could position the startup at the intersection of fintech and collectibles, a segment that has attracted increasing attention from investors in recent years.

The startup also emphasizes creator participation within its ecosystem. Users can design their own mystery packs, select card pools, define odds, and offer customized experiences to buyers. By allowing collectors and creators to build and distribute packs directly, CatchBack aims to create a marketplace-driven network effect that attracts both sellers and buyers.

Industry observers note that the global trading card market remains substantial, with billions of dollars in annual transactions taking place across primary and secondary channels. Yet much of the market continues to rely on fragmented sales platforms, in-person events, and social media transactions. CatchBack’s founders believe technology can streamline these processes while reducing friction and improving trust between participants.

With fresh capital from Y Combinator and growing momentum among collectors, CatchBack Cards is now focused on expanding its platform capabilities, attracting additional users, and continuing its mission to transform trading cards into a more transparent and liquid asset class while preserving the excitement that has long defined the hobby.
