Whoppah is Europe's largest online marketplace for second-hand designer furniture, art, and home décor. Founded in Amsterdam in 2019 by Thomas Bunnik and Evelien Bunnik-Remmelts, the platform connects over one million buyers with thousands of curated sellers across 16 countries. Unlike general classified platforms, Whoppah applies editorial curation: all items are authenticated and assessed by a team of in-house specialists. The platform offers a secure escrow-based payment system powered by STRIPE, white-glove courier logistics, and a physical showroom experience. Whoppah has raised over €22M in funding and made two strategic acquisitions: Design Market (France) and Showroommodellen (Netherlands), cementing its position as the category leader in European recommerce for design.
