What gets built, in order

Five things, in the order they get done, and together they are the definition of done for Zwaptz version one. One is already in the prototype — group trades, built without waiting for the money. Each of the rest is a specific gap with a specific consequence, and the order is argued rather than assumed.

When version one is finished

Five things have to be true. When all five are, version one is done and this campaign is finished.

  1. Every valuation is backed by what similar things actually sold for, so the number is more than an educated guess.

  2. Meeting places are suggested from real facts about real places, instead of four fixed descriptions.

  3. Zwaptz can email you. A forgotten password can be reset, and reporting something gets a reply.

  4. There is a spare copy of everything somewhere else, and we have proved it works by putting everything back from it.

  5. It runs on a computer sized for people rather than a demonstration, and anybody can use it.

  1. 01

    Comparable sales

    built, not connected

    Because it makes every valuation on the site better at once.

    The valuation runs in three stages: work out what the thing is, look up what comparable ones sold for, turn that into a range. The middle stage has no feed connected, so today a range comes from what the model already knows about a market — and because nothing was verified, every appraisal on the site is capped at low confidence. Connecting it narrows every band and is the only thing that lets confidence rise at all. Nothing else on this list changes as many screens.

  2. 02

    Group trades

    in the prototype

    Because it removes the last reason a swap fails to happen.

    Six people in one place have far more ways of matching up than two people do. Built on 8 September 2026: anybody can open a group around one of their things, anybody whose item lands in the same range can join, and the group settles the place, the time and who ends up with what. Zwaptz opens the conversation and does none of the arranging.

  3. 03

    Meeting places, built from facts

    not built yet

    Because arranging where to meet is where two people give up and move to another app.

    What exists is four fixed kinds of place with a sentence written for each. What this builds is a places feed — open now, staffed, busy at this hour, near transit — charged per lookup. It never calls a place safe; it states what is true and lets people judge.

  4. 04

    Being able to reach you

    built, not connected

    Because there is no way to email anybody today, and that shows.

    No mail server means no self-service password reset and no reply when you report something. An administrator can reset a password by hand and that is the whole of it. Since 9 September 2026 a browser can tell you an offer arrived, if you turn that on in your account — which covers the notifications and none of the rest.

  5. 05

    Backups that leave the building

    built, not connected

    Because fourteen days of backups currently sit on the machine they protect.

    Nightly backups run, are integrity-checked, and have been restored from — a real file was deleted and came back byte-identical. The copies are all in one place. Losing the machine would lose the accounts, the items, the photographs and every backup of them at the same moment.

The band is what everything runs on.

That is the whole argument for the order. Every other item on the list is a good thing to have. Comparable sales is the one that makes the number underneath all of them more trustworthy, and a swap people trust is the product.

Group trades was second on this list, for the same kind of reason: it is the feature most likely to turn somebody’s first attempt into an actual swap rather than a stalled one. It is already in the prototype, built without waiting for the money, so it goes into version one as it stands and no line of the budget pays for it twice.
