    Example of the dashboard with demo data. None of these requests are real.
    For space owners

    Your car. Your wall. Your next source of income.

    List a vehicle, storefront, building or other advertising space and receive requests from advertisers.

    • Private cars
    • Taxis and rideshare
    • Vans and fleets
    • Cargo bikes
    • Facades and side walls
    • Shop windows
    • Bars, cafés and gyms
    • Events and venues

    You set the price, the dates and the surfaces you allow. Requests depend on demand, and local rules or permits may apply.

    For advertisers

    Find, compare, request and manage in one place.

    No media kits by email. Every space uses the same fields for audience, price unit, dates and terms, so a taxi and a newsletter can sit side by side.

    Use the arrow keys or swipe to move between views.
    Seller dashboard

    Publish once. Decide on every request.

    No subscription and no listing fee. Price per week, per month or per campaign, whichever fits the space. Slotwise takes 5% from each side only when a booking goes through.

    Categories

    From a newsletter slot to a bus shelter.

    Each category counts its audience and prices its time differently. Listings keep the unit and the source, so a newsletter subscriber is never mixed up with a passerby.

    How it works

    Three steps on each side.

      What you can check

      The same facts on every listing, before you ask.

      1. Audience and its source
      Owner-reported, platform analytics, third-party measured or publisher circulation.
      2. Availability by month
      Open, limited and booked months, and the earliest start date.
      3. Terms set by the owner
      Artwork lead time, installation rules and the free cancellation window.
      4. Total cost
      Base price for your dates plus the 5% Slotwise service, added up before you send a request.

      Slotwise does not verify audience figures yet. How listings will be reviewed is still being decided.

      Questions

      Frequently asked questions

      Answers marked Pending decision are not settled yet. We say so rather than guess.

      Fees

      5% from each side, only when a booking happens.

      No subscription, no listing fee, and nothing to pay for searching, saving, comparing or asking. Both fees are worked out from the base price, never one on top of the other.

      Example amounts in euros. Demo figures, before taxes and payment processing costs. Payments are not live in this prototype.
