CapSeal - Vehicle marketplace scenario

This is an illustrative scenario, not a customer. CapSeal is pre-launch. Every figure below is modelled from published industry data and stated assumptions, which are set out in full further down so you can disagree with them. We will replace these with named, measured references when we have them, and not before.

The situation

Where the organisation starts

A marketplace carries roughly 180,000 vehicle listings a year across private and dealer sellers.
Listing photographs are uploaded from the camera roll. Stock images and photographs reused from other listings are common and are found only when a buyer complains.
Condition disputes after sale are absorbed by the platform, in refunds, in mediation time, and in the trust that leaks away each time.

The assumptions behind those numbers

180,000 listings a year; 34% converting to a completed sale.
Reused and stock photograph rate measured by perceptual duplicate detection across a sample, not by seller admission.
Enquiry uplift assumes the verified badge is displayed in search results, not only on the listing page. It is drawn from comparable trust-signal experiments in other marketplaces, and is the least certain figure here.
Dispute reduction applies only to condition disputes, which are roughly 60% of the platform's dispute volume.
Seller adoption at 45% in the first year, concentrated among dealers.

What changes

How the process differs

The seller captures in the app

Photographs are taken through the marketplace's own flow and sealed on the device, so a listing photograph is provably of that vehicle, taken by that seller, at that time.

Buyers can see the difference

A verified capture badge in search results. Honest sellers get something for the extra two minutes, which is what makes adoption spread without a mandate.

Reuse becomes detectable

Sealed evidence carries an identity. The same photograph appearing on a second listing is visible rather than invisible.

Disputes have an evidentiary basis

Sealed condition photographs at listing and at handover give mediation something better than two conflicting accounts.

Honest limits

What this model does not claim

A model is an argument, not evidence. These figures show what follows if the assumptions hold for your organisation, and the point of publishing them in full is so you can check whether they do.

Sealing evidence at capture does not detect every fabrication, does not establish that a truthful-looking document is true, and does not determine intent. The Product Disclosure sets out the boundary precisely.

Start with one category.

Dealers first, a verified badge in search, and a measured lift against your own baseline.
