1stDibs is an online marketplace for luxury design items, connecting buyers with vetted sellers of vintage, antique, and contemporary furniture, home décor, jewelry, watches, art, and fashion. The platform hosts approximately 1.9 million listings from roughly 5,700 sellers across more than 200 countries, with an average order value of around $2,600. 1stDibs makes money in two ways: transaction fees (commissions on completed sales, roughly 75% of revenue) and monthly seller subscription fees (roughly 25% of revenue). The company does not own inventory — it operates as a pure marketplace, which keeps gross margins in the 71–73% range. Key buyer segments include individual consumers and trade buyers (interior designers), the latter accounting for roughly 31% of GMV and served through a dedicated Trade 1st program offering exclusive pricing and support. 1stDibs vets sellers before onboarding them, which is a core trust mechanism, and backs purchases with authenticity, money-back, and price-match guarantees. About 73% of new user sessions come from organic, non-paid channels, which management views as a key advantage in reducing buyer acquisition costs. Growth levers include conversion rate optimization, international buyer expansion (currently only 20% of buyers despite 40% non-U.S. traffic), pricing transparency via ML-based tools, and an early-stage advertising business. 1stDibs is also deploying AI across pricing, personalization, and engineering productivity.
