Alt.xyz operates a platform for the collectible card market, which it estimates at $5 billion. The company's core services allow collectors to buy, sell, value, and store cards, positioning them as liquid, alternative assets. Its marketplace moves hundreds of millions in gross merchandise value (GMV).
A key technical component is the Alt Value system, a proprietary pricing engine that analyzes transaction history and market data to provide real-time valuations for over 10 million cards. The platform also includes a secure, insured vault for storage and a lending service that enables collectors to borrow against their holdings without selling.
The company is expanding its team across engineering, product, marketing, and operations. It was recognized as one of the best remote-first places to work in 2021 by Built In.
