1stdibs.com, Inc.

Company Overview We are one of the world’s leading online marketplaces for connecting design lovers with many of the best sellers and makers of vintage, antique, and contemporary furniture, home d cor, jewelry, watches, art, and fashion. We believe we are a leading online marketplace for these luxury design items based on the aggregate number of listings on our online marketplace and our Gross Merchandise Value ( GMV ). Our sellers, who undergo an evaluation by our in-house experts to vet the quality of their inventory, in-depth marketing content, and custom-built technology platform create trust in our brand and facilitate high-consideration purchases of luxury design items online. By disrupting the way these items are bought and sold, we are both expanding access to, and growing the market for, luxury design. 1stDibs began over two decades ago with the vision of bringing the magic of the Paris flea market online by creating a listings site for top vintage and antique furniture sellers. The quality of our initial seller base enabled us to build a reputation in the design industry as a trusted source for unique luxury design. Since then, we have strengthened our brand as well as deepened and broadened our seller relationships. We launched our e-commerce platform in 2013 and transitioned to a full e-commerce marketplace model in 2016. We had 7.8 million users and approximately 1.9 million listings as of December 31, 2025, compared to 7.0 million users and approximately 1.8 million listings as of December 31, 2024.
