1stDibs vs. Monde Singulier: Open Marketplace or Curated Design Platform?

A curated design platform selects which designers and pieces appear in its catalog. An open marketplace lets any seller list. The difference determines who controls quality: on a curated platform, the editorial team does. On a marketplace, each seller does.

TLDR

• 1stDibs lists 1.9 million items across all periods; Monde Singulier curates roughly 150 contemporary designers
• 1stDibs commissions reach 20-25%, costs embedded in listed prices; Monde Singulier prices come direct from the designer
• Provenance on 1stDibs depends on individual dealers; Monde Singulier authenticates at the source
• 1stDibs is self-service; Monde Singulier offers full-service support through installation
• 1stDibs suits buyers who want breadth across eras; Monde Singulier suits those focused on living designers

What Is 1stDibs and How Does It Actually Work?

1stDibs is a New York-based online marketplace for luxury furniture, fine art, jewelry, and decorative objects. Founded in 2001, the platform connects independent dealers and galleries with buyers worldwide. Sellers manage their own inventory, photography, and pricing.

As of December 2025, 1stDibs hosted approximately 1.9 million listings from 5,700 unique sellers, serving 60,700 active buyers worldwide, according to the company's 10-K Annual Report filed with the SEC. That active buyer count dropped from 64,300 the previous year.

"Luxury will become as digital as any other," said David Rosenblatt, CEO of 1stDibs, in a Robb Report interview explaining the company's long-term thesis as it prepared for its IPO.

The catalog is vast. A search for "contemporary dining table" returns thousands of results spanning mass-produced pieces and genuine designer work. Buyers with time and expertise can put that breadth to use. Those without will spend most of their time filtering.

How Do the Commission and Pricing Models Compare?

1stDibs charges sellers a commission of 15% plus a 3% transaction fee, with rates reportedly reaching 20-25% depending on seller tier and agreement, according to the 1stDibs Support Center and independent seller analyses. These costs are invisible to the buyer but embedded in the listed price: dealers factor platform fees into their asking prices.

Monde Singulier works with designers, not through intermediary dealers. The listed price reflects the designer's own pricing. There is no commission chain between maker and buyer.

"The lesson of the internet is power shifts from those who control distribution, meaning supply, in every industry, to those who control the buyer," said David Rosenblatt, CEO of 1stDibs, on the Recode Decode podcast. The statement, intended as a defense of 1stDibs' marketplace model, also describes why direct-to-buyer platforms have gained ground: they shorten the chain between creator and collector.

For trade professionals making multiple purchases per project, the pricing gap compounds. Monde Singulier's PRO program offers dedicated trade pricing, project-based support, and volume conditions that a standardized commission structure does not accommodate.

Which Platform Is Better for Contemporary Collectible Design?

1stDibs was built on the Paris flea markets and the world of established antiques dealing. Its catalog runs deepest in mid-century modern, Art Deco, and period furniture. Contemporary collectible design exists on the platform, but it shares space with vintage, antique, and industrial categories. Finding and evaluating contemporary work against peers takes effort.

Monde Singulier is exclusively contemporary. Every designer on the platform is alive, working, and producing new pieces. The catalog covers the current state of collectible design across more than 20 countries.

The global luxury furniture market was valued at USD 25.28 billion in 2025 and is projected to reach USD 42 billion by 2034, with Europe holding a 37.31% share, according to Fortune Business Insights. Contemporary collectible design is the fastest-moving segment within that growth. A platform built around it can index deeper than one where it is a subcategory among many.

For decorators and architects sourcing statement pieces for new projects, Monde Singulier's focus removes the need to filter out antiques, reproductions, and outdated inventory. Everything on the platform is current, available, and produced by a designer the platform knows.

How Does Each Platform Handle Authenticity and Provenance?

On 1stDibs, authenticity depends on individual dealers. The platform has vetting processes and dispute resolution, but with 5,700 sellers managing their own listings, consistency varies. Misattributed pieces have surfaced over the years, particularly in vintage categories where provenance chains can be long and poorly documented.

In 2024, 1stDibs shifted its seller acquisition strategy to focus on fewer, more engaged sellers, reducing unique sellers from 7,800 in 2023 to 5,900 in 2024, according to the company's Q4 2024 Earnings Call. The reduction suggests the platform sees the quality-control cost of scale.

Monde Singulier sources every piece from the designer's atelier. There is no intermediary chain. The platform documents each work and maintains a direct relationship with the maker. Authentication happens before a piece is listed, not retroactively.

Collectors building holdings for the secondary market know this. Auction houses like Christie's, Sotheby's, and Phillips require a clean provenance chain from studio to collection. A direct-from-atelier record provides that by default.

What Level of Service Can You Expect from Each?

1stDibs operates as a self-service marketplace. The buyer searches, evaluates, negotiates with the dealer, and arranges logistics. The platform provides tools and some buyer protection, but the transaction is the buyer's to manage.

1stDibs' full-year 2025 net revenue reached USD 89.6 million, with the company achieving its first Adjusted EBITDA-positive quarter as a public company, according to its 2025 financial results. That revenue comes from seller fees and subscriptions. The business model connects parties; it does not manage the transaction end-to-end.

Monde Singulier runs a full-service operation. The platform produces professional photography and 3D visualizations for every piece, facilitates direct communication with designers, manages custom commissions, coordinates production follow-up, and handles international shipping through white-glove installation. For a private collector buying one piece, self-service may be enough. For a decorator managing a multi-piece project across borders, the operational difference is concrete.

The PRO program extends this: dedicated trade pricing, project timelines, and a single point of contact for sourcing across the full roster of designers.

1stDibs vs. Monde Singulier: Which Should You Choose?

Choose 1stDibs if you need a large inventory spanning all periods and styles, are comfortable managing your own sourcing, and can evaluate quality and authenticity independently. The platform remains the strongest destination for vintage and antique design, and its scale is useful for tracking down specific historical pieces.

Choose Monde Singulier if you are focused on contemporary collectible design, want transparent pricing without layered commissions, need documented provenance from the source, and value integrated project support from discovery through installation.

Many professionals use both. The platforms answer different questions. But as the market moves toward curation and direct relationships, the way Monde Singulier operates (fewer pieces, better selected, with full service) fits how the most discerning buyers already work.
