Alt

Alt is a sports card trading platform founded in 2020 by Leore Avidar, with a pitch aimed at serious collectors and investors: combine the Vault (physical storage and insurance), Auction House (timed sports card auctions), Marketplace (fixed-price listings), Cash Advance program (liquidity against vaulted cards), and ALT Value (portfolio valuation analytics) into a single integrated operating system for the hobby. The company raised a $31M Series B led by Spark Capital in 2022 (alongside earlier raises from a16z crypto and others), and has onboarded collectors including Tom Brady, Alex Rodriguez, and major PE firms active in the space. Unlike Collectable or Rally, Alt is not a fractional-ownership platform — users own their cards outright.

The flagship product is the Alt Vault, a secure physical storage and insurance facility in Delaware where sports cards held by Alt users are stored, insured, and authenticated. Storage is free for cards listed for sale, or roughly $20/card/year for private storage. The fee structure is straightforward: a 9% seller fee on Marketplace (fixed-price) sales, and a 7% seller fee on Auction House sales for vaulted cards (or 12.5% for non-vaulted). Buyers face a 15% Buyer Premium at auction plus a separate 3% payment processing fee. This makes Alt competitive with eBay for marketplace sales but meaningfully more expensive than eBay for auctions; however, the vault infrastructure, payment advance program, and serious-collector audience are meaningful differentiators.
