On building a JCard.

Shidduchim are sacred work. The vessels we use to do them — the resume, the phone call, the photo passed around — were built for a smaller world. This is what we built, and the boundaries we drew, and the promises we are making in writing.

Why we built this.

A shidduch resume reinvents itself every time. One has photos at the top, another puts family at the bottom. The fields shift, the order shifts, the labels shift — and a shadchan reading thirty of them in a week has to translate every single one before she can compare a thing¹. The work of redting becomes the work of cleanup. The story that should reach a family arrives blurred.

We watched this happen, asked enough shadchanim to fill a room, and concluded something obvious: the document should be standard, but the voice should not. The schema fixed, the words your own.

That is the entire premise of JCard. Same nine sections, in the same order, every time. The fields are honest scaffolding; the writing inside them is yours. Comparison stops being a chore and becomes literal — two cards lay down on one spine.

"The card is standard so that comparison can be honest. The voice is yours so that the comparison can be of people." — a shadchan in Lakewood, conversation in Adar

The schema, in plain language.

Nine sections, in this order: identity, hashkafa, education, profession, family, about, looking for, references, logistics. They cover what a shidduch needs to start a conversation: who, how observant, where you learned, what you do, where you come from, who you are in your own words, what you'd want, who can vouch, where you'll go.

We chose nine deliberately. Six would have hidden too much; twelve would have started inviting the wrong fields. A hashkafa spectrum sits in section two² — one axis from traditional to modern — because a label like "Chabad" or "Modern Orthodox" is the start of a conversation, not the end.

What is not on a JCard, deliberately: no height-weight grid, no shoe size, no parnassah numbers, no measurement of a person against an averaged ideal. The card is for a human being, not a search filter.

Your card, your locks.

Every field on a JCard can be set to one of four levels. They are the same four levels, in the same order, on every card — another scaffold, like the schema. A single chooses where each field sits; we just enforce it.

1. ○ Public Visible to anyone holding the link. Default for the parts of your story that aren't intimate — your name, your age, your hashkafa, your about.
2. ◐ Shadchan only Visible to vetted shadchanim. Default for family details and references — the parts that should travel through a trusted intermediary, not in the open.
3. ◑ On interest Hidden until both sides express interest. A natural unlock when things get serious. Default for the portrait photo³.
4. ● Locked Hidden until you grant access by name. The field exists, but only you decide when it shows.

Defaults matter and we have spent more time on them than on any other choice in the product. Photo at on interest, family at shadchan only, references at shadchan only. A single who never touches a setting still has a tznius card.

The Chevra, in plain language.

Shadchanim do their best work in conversation with other shadchanim. The Chevra is the room where that conversation happens — a private, by-referral network. No member joined by asking; every one was vouched for by another. One vouch is enough; two seconds is the quiet ideal.

Inside the Chevra, shadchanim share open singles, ask the room for a name, post a mazel, gather for kinus, and access a small beis medrash of hadracha written by the chevra itself. JCards in the room are anonymized when posted publicly — initials, age, region, blurb — until a shadchan messages the poster directly.

We did not build a profile-and-rating system. The Chevra has no "top shadchan" leaderboard, no public statistics, no review system. Trust is interpersonal; the product just gives it a room.

How we earn (and how we don't).

JCard is free for everyone who uses it — singles, families, shadchanim — until a shidduch closes. When a couple gets engaged, the customary shadchanus is collected through the platform, and we take ten percent. The rest goes to the shadchan.

That is the entire business model. We do not charge subscriptions. We do not charge to share. We do not charge to receive. The platform fee is taken out of the gelt the family was already going to pay — families never pay JCard a penny they wouldn't have paid the shadchan directly.

We earn when the shadchan earns. We earn nothing when she earns nothing. The incentive is honest in one direction only: more shidduchim.

And there is no other revenue line. No advertising, ever. No selling of data, ever. No "anonymized" data products, ever. No third-party partners reading your card. The covenant at the end of this essay puts these in writing.

What JCard is not.

The shidduch world has watched a generation of dating apps appear and quietly do harm. We are not building one of those. To be explicit:

• JCard is not a swipe app. There is no carousel, no algorithm matching singles to other singles, no "you might like" surface anywhere.
• JCard is not a profile app. Your card is not browsable. A single cannot search for another single. The only way a JCard reaches a person is through a shadchan choosing to share it.
• JCard is not a public marketplace. Family details, references, and contact stay behind locks the single sets. Even names are not searchable.
• JCard is not an algorithm. We do not score compatibility, predict matches, or rank shadchanim. A computer is bad at shidduchim. A shadchan is good at them.
• JCard is not a replacement for the shadchan. Every shidduch on the platform passes through a human shadchan. We sometimes describe ourselves as infrastructure for the shadchan: a clean card, a quiet room, a respectful fee.

With rachmonus.

We have consulted with shadchanim across Chabad, Yeshivish, Modern Orthodox, Chassidish, and Sephardi communities. We have spoken with rabbanim. We have shown the product to singles, to mothers of singles, and to fathers who think the whole project is unnecessary — and we have changed it after every conversation.

The product is designed to feel quiet. There is no celebration of finding a match in the user interface, only the moment of the engagement — which gets the warmest page in the product, because the celebration belongs to the families⁴. There are no streaks, no points, no nudges to be more "active." A single who logs in once a month is a healthy user.

We are aware of the cost of getting this wrong. We will get individual things wrong; we will not get the foundation wrong. The covenant below is the part we are putting our names to.

Our covenant.

The following commitments are not aspirational. They are written into our terms of service, signed by the founders, and reviewable by any rav consulted by a member or a family.
