Each seat sees exactly what its work requires, and everything a seat does is written to the record. HICONIUM ## Collector For private collectors who want to manage their vehicles as assets, track market values, and sell discreetly when needed. - Escrow handling via HICONIUM - Commercial terms agreed at admission [Request membership](https://hiconium.dev/sign-up) HICONIUM ## Dealer For certified partner dealers who handle the operational part of the sale — viewings, logistics, documents — under the HICONIUM triangle model. - Success and platform fees agreed at certification - Escrow handling via HICONIUM [Register your dealership](https://hiconium.dev/partners#dealers) HICONIUM ## External Manager For a family office, assistant or advisor operating inside a Collector’s account — invitation and permissions only, no garage of its own. - No subscription — invited by a Collector - Permissions set and revoked by the Collector - Every action recorded on the account [Request an invitation](https://hiconium.dev/membership#external-manager) Feature comparison ## What each seat can do Swipe sideways for every seat → | Capability | Collector | Dealer | External Manager | | --- | --- | --- | --- | | Account, login and KYC verification | | | | | Own garage — manage vehicles, photos and documents | | | | | Visibility per car: private, shared or public web | | | If enabled | | HICON-PRICE and sealed-bid count per vehicle | | | If enabled | | Market indices and model trends | | | If enabled | | Favourites and watchlists | | | If enabled | | Place HICON-BIDs | | | If enabled | | Trigger "Sell my car" | | | | | Assign or change the dealer per vehicle | | | If enabled | | Run viewings, logistics and contract upload | | | | | Messaging within defined relationships | | | If enabled | | Digital ownership transfer after a deal | | | | | Invite an External Manager | | | | "If enabled" is the External Manager in one line: every capability is a checkbox the Collector grants — viewing prices and bid counts, editing vehicle data, bidding on the Collector's behalf, talking to the assigned dealers — and every grant is revocable and recorded. An External Manager is invited by a Collector; there is no application. While the founding cohort fills, invitations run through the concierge — write to welcome@hiconium.com from the inviting Collector's account. Selling logic ## A sale with no stage fright Discretion is the product: the market never sees a listing, and the strongest buyers never see each other. 01 · The trigger The Collector triggers the sale on a car. Nothing is public: the platform notifies the top six sealed bidders, and only them. 02 · The window A thirty-day viewing window, run by the assigned dealer as the operational hub — viewings, logistics, documents, all recorded on the chassis. 03 · The offers Final offers are collected through the platform, sealed. The number stays a number; the identities stay private. 04 · The transfer The buyer funds escrow, the contract is uploaded, and ownership transfers digitally — the sale becomes part of the car’s permanent record. Benefits ## Financial sense first. Then the fun Membership unlocks the platform’s pricing instruments and the private network around them — exact prices per chassis, and rooms where cars, art, fashion and architecture meet on equal terms. ### Collection valuation One exact HICON-PRICE per chassis, held current, with the evidence behind it. ### Market instruments The indices and model trends that carry your cars, with historical pricing depth where the record allows it. ### Privacy controls Share per car, per field, per audience — nothing leaves the vault without your say. ### The HICON-SCORE The more of your collection’s history you document, the higher your score — and the more the platform can prove on your behalf. ### Member events Occasions where cars, art and design intersect — access follows standing, not spend. ### One portal, many collections External Managers run several collections through a single account, with permissions their Collectors control. Access is by application while the founding cohort fills. Companies looking to build on the layer belong in [the partner universe](https://hiconium.dev/partners).
