1stDibs is an online marketplace for luxury and vintage items, including antique furniture, fine jewelry, vintage fashion, and art. It connects buyers with top sellers from around the world, offering a carefully curated selection of extraordinary pieces. Items are listed by sellers and sold through the platform, which earns revenue from commissions on sales, listing fees, and premium services; there is also an auction feature that lets items be bid on to potentially achieve higher prices. The business does not hold inventory, helping reduce overhead and risk. The key differentiators are its strict curation, emphasis on authenticity and luxury, and a trusted, global network that attracts high-value transactions. The company's goal is to facilitate access to rare, high-quality pieces for discerning collectors, interior designers, and affluent buyers while maintaining sustainable revenue through commissions, listings, and premium services.
