The Curator's Advantage: How Moshe Silberberg Built RIJOUX — and Why He's Betting Its Next Chapter on YESODI

A Business Born in the Trade, Not the Trend

Some luxury brands are founded on a mood board. RIJOUX was founded on a lineage.

Moshe Silberberg grew up inside the actual machinery of the luxury business — not the marketing of it, the trade of it. His father dealt diamonds. His mother and grandfather spent more than forty years in fashion in Israel. The family moved through the cities that have always formed the arteries of the global stone and goods business: Antwerp, the world's diamond clearinghouse; Kinshasa, close to the source; Panama City, a crossroads of duty-free luxury and Latin American commerce.

That's an unusual education, and it produces an unusual operator. Most people enter luxury through the storefront. Silberberg entered through the supply chain — which means he learned the two things that actually govern this industry before he ever learned to merchandise a window:

1. Provenance is everything. Where a thing comes from, and who vouched for it.
2. Relationships are the real inventory. Stones and garments move on trust, not on paperwork.

RIJOUX — a fashion, jewelry, and diamond house, anchored by boutiques in Tel Aviv and now expanding aggressively into the U.S. digital market — is what happens when someone raised on both of those principles decides to build something of their own.

What RIJOUX Actually Is

RIJOUX sits in a category that is genuinely difficult to execute: curated multi-brand luxury, spanning three product worlds that most retailers keep separate. Fine jewelry and diamonds. The foundational category, and the one carrying the deepest family expertise. This is a business where a single bad sourcing decision is fatal to a reputation — and where decades of relationships with cutters, dealers, and designers are an asset no amount of capital can shortcut. Designer fashion. Curated, not warehoused. RIJOUX carries pieces sourced directly from designers and fashion-week showrooms rather than from generic wholesale channels — which is why the assortment reads as a point of view rather than an inventory list.

Lifestyle curation. Accessories, statement pieces, and the surrounding objects that turn a purchase into a personal signature.

The clientele reflects the founder's own map of the world. RIJOUX serves Jewish communities globally — a genuinely international, high-trust, referral-driven customer base — alongside local shoppers and international visitors passing through Tel Aviv. Different locations, different age groups, different aesthetics, one standard.

The Buying Philosophy: Sourced at the Show, Not the Catalogue

Here's where Silberberg's method separates from ordinary retail. He buys at fashion weeks — in person, on the ground, globally. Milan and Paris for luxury and high-end houses. Tbilisi for streetwear energy. Kyiv for feminine design. New Zealand Fashion Week for pieces the rest of the market simply hasn't seen. He works the trade showrooms, places orders directly, and comes home with collections that competitors can't source because they never went. And his criteria for taking on a brand are notably modern. He doesn't just evaluate the product. He evaluates the whole gravitational field around it — press coverage, social presence, follower base, the runway show itself, the bloggers and models who've attached themselves to it. In other words: he underwrites cultural momentum, not just margin.

His summary of the whole business is one of the more clear-eyed lines you'll hear from a luxury buyer:

"Consumers buy what they like; marketing influences customers' choices." No mystification. No pretending taste is magic. Buy what people will love — then do the work of making them aware of it.

That sentence, held up to the light, is also the seed of everything that follows in this story. Because if marketing is what moves the needle, then who controls your marketing is the single most important strategic question a brand can ask.

The American Expansion: Meeting the Customer Where She Already Is

RIJOUX's U.S. growth strategy is a masterclass in pragmatism. Rather than burning capital trying to force cold traffic to a standalone site, Silberberg leads a multi-marketplace distribution strategy — placing RIJOUX inventory across the platforms where American buyers of designer fashion and fine jewelry are already searching, browsing, and transacting:

• Poshmark — the community-driven resale engine, with a customer who follows sellers as personalities. • Depop — the Gen Z and young-millennial style market, where curation and aesthetic identity drive the sale. • Grailed — menswear and designer credibility, an audience that knows exactly what it's looking at. • eBay — global reach, auction dynamics, and the deepest pool of serious collectors in the world. • Amazon — scale, search intent, and logistics infrastructure.

Each channel reaches a different buyer with a different reason to buy — and RIJOUX serves all of them from its own warehouse, with hands-on logistics rather than outsourced fulfillment. That last detail matters more than it sounds. Owning the warehouse means owning the condition of the goods, the accuracy of the listing, the speed of the ship, and the quality of the packaging — which, in luxury resale, is the brand experience.

It's a strategy that has given RIJOUX something rare: real, diversified, multi-platform U.S. revenue built without a nine-figure marketing budget.

The Realization: You Can Rent Reach, But You Can't Rent a Relationship

And yet — this is where the story gets interesting.

Silberberg has now spent years operating at a high level on other people's platforms. Which means he's also spent years learning their limits, from the inside:

You don't own the customer. A buyer who loves your work on a marketplace belongs to the marketplace. You cannot email her. You cannot retarget her. You cannot tell her the new collection landed.

You don't own the data. Every transaction generates enormously valuable information — who buys, what they pay, what they browse first, what they come back for. On a marketplace, that data enriches the platform's model, not yours. You don't own the algorithm. You rent placement. The rules change without notice, the fees rise, and a business you spent five years building can be reranked into invisibility on a Tuesday morning.

You're always competing on someone else's terms. Marketplaces are designed to make sellers interchangeable. That is the opposite of what a curated luxury brand is trying to be.

For a business whose entire value proposition is trust, taste, and relationship, that arrangement is structurally backwards. RIJOUX's greatest asset — the community that believes in Moshe's eye — was the one asset the platforms wouldn't let him hold.

So he's moving.

Why YESODI?

Silberberg is now focusing his sales and community-building efforts on YESODI — and the reasoning maps almost point-for-point onto everything the RIJOUX business has learned the hard way.

1. Own your data

On YESODI, the data a business generates comes back to the business. Not as a dashboard of vanity metrics — as an actual asset. YESODI's model returns data value to the posting business, with dividends distributed quarterly. For an operator like Silberberg, who thinks in terms of inventory and provenance, this is simply the correct accounting: the customer relationship is an asset on my balance sheet, not on someone else's.

1. Control your own algorithm

The framing YESODI has built its case on is that the incumbent platforms broker your algorithm — they sit between a creator and the people who already chose to follow them, and charge for the privilege of reconnecting them. YESODI removes the broker. The creator decides who reaches them and who they sell to. For a curator whose entire business is his judgment, an algorithm he doesn't control is an existential risk.

1. Be in the AI's answer, not fighting for feed placement

This is the strategic bet, and it's the sharpest one. Discovery is moving. Increasingly, buyers don't scroll — they ask. They ask ChatGPT which jeweler to trust. They ask Claude to compare designers. They ask an AI assistant to find a piece. In that world, the winner isn't whoever gamed the ranking; it's whoever the AI actually knows about, understands, and cites. YESODI is architected as AI-first discovery — structured so that businesses on the platform are legible to AI engines and surface inside the answer. Silberberg's read is that this is a generational repositioning opportunity: instead of RIJOUX competing against a thousand jewelry listings for a slot in a feed, RIJOUX becomes the answer to "where do I find a curated designer piece with real provenance?"

Getting in early on that is not a marketing decision. It's a land grab.

1. Remarketing and channel governance

On YESODI, RIJOUX governs its own advertising channels and can remarket to its own audience — the basic capability that marketplace selling structurally denies. A customer who bought earrings in March can actually hear about the new collection in September. That is the entire difference between a transaction and a customer.

1. Monetization for creators and followers

YESODI is ad-free and profit-sharing by design, with monetization flowing to creators and to the community around them. Silberberg intends to use this fully — profit-sharing with his own followers and with the ecommerce professionals in his network across New York, Los Angeles, Miami, and Israel.

It's worth pausing on how naturally this fits his background. The diamond trade has always run on shared upside — brokers, finders, partners, everyone in the chain compensated for the value they brought. YESODI's model isn't foreign to him. It's the trade's oldest logic, finally expressed in software.

1. Super affiliation, five levels deep

This is the piece Silberberg is most energized about. YESODI's affiliate structure runs five levels deep, which means the trust in a community compounds rather than terminating at a single referral. When someone he's worked with brings in someone they trust, and that continues outward, the entire network is rewarded for the connections it actually makes. For a man whose career was built precisely on being the connector — the one who knows the dealer, the designer, the buyer, the warehouse — five-degree affiliation isn't a feature. It's a formalization of the way he has always done business. It turns two decades of relationships from an informal advantage into a compounding, measurable, monetized asset.

1. Bringing the network with him

Silberberg isn't arriving alone. He intends to bring other e-commerce brands he has worked with onto the platform — operators, sellers, and merchants he's built relationships with across the U.S. and Israeli markets. (And Gal Keitelman wants to jump in on this as well.)

This is the single most valuable thing a person of his standing can contribute to a young platform, and it's why the partnership is more than a merchant signup. RIJOUX is a beachhead. The network behind it is the actual prize.

The Full Playbook: Products, Events, Services

What makes the RIJOUX–YESODI fit unusually complete is that Silberberg wants to use the whole platform, not one corner of it.

Products. The core commerce — jewelry, diamonds, curated designer fashion — sold direct to a community that follows him rather than a feed that ranks him. Events. Trunk shows, private viewings, collection launches, community gatherings across New York, LA, Miami, and Tel Aviv. Luxury has always been sold in rooms. YESODI's event infrastructure lets the digital community and the physical room finally be the same audience — and lets the people who help make an event happen share in what it earns.

Services. This is the underrated frontier. Silberberg's expertise — sourcing, authentication, diamond and stone knowledge, buying, curation, e-commerce operations — is itself a product. A service line built on that expertise turns accumulated judgment into recurring revenue, and gives the community access to the thing they actually value most: his eye.

The Man Behind the Model

Business models are easy to write down. What makes them work is character, and Silberberg's reputation is the quiet engine under all of this.

He is, by any measure, extraordinarily well connected — across the diamond trade, the designer fashion world, the Israeli business community, and the American e-commerce sector. Those are four distinct networks that rarely overlap in one person.

But connections without integrity decay fast, and in the diamond business they decay fastest of all. What sustains a career like his is the thing his family's trade demanded from the beginning: you are only as good as your word. Honest representation of a stone. Straight dealing on a price. Customer service that treats a buyer as a relationship rather than a transaction. Real value delivered, every time, so the client comes back and brings someone with them.

And running through all of it, a genuine respect for individuality — the belief that the point of a beautiful object is not to signal conformity but to let a person say something specific about themselves. It's the through-line from the boutique to the marketplace to YESODI. RIJOUX has never been in the business of selling people what everyone else has.

Why This Partnership Makes Sense

Strip away the platform language and the alignment is almost elegant in its simplicity.

RIJOUX is a business built on trust, curation, provenance, and relationships.

YESODI is a platform built to give trust, curation, provenance, and relationships back to the people who create them — instead of renting them out by the impression.

Moshe Silberberg spent his life learning that the value in luxury doesn't live in the object. It lives in the chain of people who vouched for it.

YESODI is the first platform built to pay that chain.

Follow the money.
