Catawiki Tech Stack

Expert-curated online auction marketplace for collectibles and special objects

Internet Marketplace Platforms Amsterdam, North Holland 501–1,000 employees Founded 2008 Privately Held

Catawiki runs a curated auction marketplace where in-house specialists validate and stage 100,000+ objects weekly across art, design, jewellery, fashion, and collectibles. The tech stack (Ruby, Kotlin, TypeScript, Kubernetes, GCP) and active projects reveal a platform scaling microservices and data pipelines to handle high-volume auctions—a capital-intensive infrastructure challenge for a marketplace. Hiring skews heavily toward sales (34 roles) relative to engineering (17), consistent with a seller-acquisition and category-expansion strategy rather than platform overhaul.

About Catawiki

Catawiki is a curated online auction marketplace headquartered in Amsterdam with over 750 employees across seven countries. The business model centers on expert curation: each object listed passes review by in-house specialists before entering auction. The catalog spans art, design, jewellery, fashion, classic cars, and collectables. Active projects include seller base development, auction optimization around seasonality, category expansion (coins & banknotes, jewellery), and carrier integration. Current operational pain points cluster around scaling: expanding and improving seller performance, handling high-volume auction requests, diversifying lot selection, and maintaining data consistency across platform growth.
