Catawiki

Catawiki is an online auction marketplace headquartered in Amsterdam, Netherlands, specializing in special and collectible objects. Founded in 2008, it runs curated weekly auctions across categories such as art, jewelry, watches, classic cars, coins, stamps, comics, wine, and other collectibles, where every lot is reviewed and vetted by in-house experts before it goes live. Catawiki operates as a consumer marketplace connecting buyers and sellers internationally; it does not publish a public developer API or partner integration program, and runs its engineering on a Ruby/Go/Kafka stack visible across its public GitHub organization. This profile was added to the API Evangelist network as a venture-portfolio lead (Accel, Northzone) and enriched with verifiable identity and domain-security signals.

Catawiki is profiled on the APIs.io network. Tagged areas include Company, Consumer, Marketplace, Auction, and Collectibles.
