What StarStock does
StarStock is a consumer-facing digital marketplace for authenticated and graded sports trading cards, founded in 2023 by Scott Greenberg, Nigel Eccles (co-founder of FanDuel), and Mike Kuchera, and headquartered in Mamaroneck, United States. The platform's core product workflow requires holders to submit physical cards, which StarStock authenticates, grades, and vaults before issuing digital representations that can be traded on the marketplace. Card prices update in real time based on athlete game performance and brand value, a mechanic the company markets as a 'stock market for athletes.'
The underlying technology combines a physical custody/grading service with a digital trading venue and a continuous pricing engine that ingests sports results. Since launch, the platform reports facilitating over 600,000 cumulative card trades and adding more than 50,000 cards per week, indicating active two-sided liquidity across categories such as baseball, basketball, football, and hockey. The platform is browser-based with no disclosed mobile app.
StarStock monetizes through transaction fees on peer-to-peer trades of authenticated cards, serving a horizontal segment of sports card collectors, hobbyists, and 'athlete-performance' investors. The company is private and venture-backed, with Andreessen Horowitz (a16z) leading a Series A in October 2024 to scale operations and expand the platform. The business model is unproven at scale in terms of disclosed unit economics; revenue and pricing are not publicly disclosed.

StarStock competitors and assessment
Company assessmentDirect peers
- PWCC Marketplace: One of the largest online sports card trading marketplaces with auction and fixed-price formats. Most directly comparable to StarStock on product (authenticated sports cards), target customers (collectors/traders), and marketplace transaction model.
- Goldin Auctions: Premier sports card and memorabilia auction house with strong authentication practices and a digital marketplace. Competes for the same high-end collector and investor customer base that StarStock targets.
- Fanatics Collect: Fanatics' dedicated sports card trading card marketplace with vertically integrated authentication. Operates at greater scale and with deeper sports league relationships than StarStock, making it the most threatening direct peer.
- Alt: Alternative asset platform offering vaulting, authentication, and trading of collectible assets including sports cards. Closely comparable business model: custody + grading + secondary trading.
- Collectable: Fractional investment platform for high-value sports cards, allowing investors to buy shares in specific graded cards. Comparable investor-focused angle and pricing transparency feature.
- StockX: Authenticated resale marketplace for sneakers, apparel, electronics, and trading cards with real-time pricing mechanics analogous to StarStock's athlete-linked pricing. Comparable marketplace model and 'stock-market-like' positioning.
Broad incumbents
- eBay: Largest horizontal online marketplace with a deep sports card category and authentication partnerships (PSA). Competes on liquidity and audience scale rather than specialization in authenticated sports card trading.
- PSA (Professional Sports Authenticator): Dominant third-party sports card grading service. While not a marketplace, PSA's grading and price-guide data shape the entire sports card market and effectively sets the trust standard StarStock must meet or surpass.
Emerging players
- MySlabs: Digital vaulting platform for graded sports cards enabling online trading and portfolio tracking. Overlaps with StarStock on the digital trading and vaulting layer of the value chain.
Others
- Sotheby's / Christie's Sports Memorabilia: Luxury auction houses operating sports memorabilia and trading card auctions. Comparable at the high-end of the collector market where authentication and provenance pricing matter most, though their core business is broader luxury goods.
