Programmatic advertising, without the surveillance.
Buy and sell display inventory with contextual targeting, a second-price auction you can audit, and a single published fee. The parts of ad tech people distrust are the parts we left out.
Contextual, not personal
Page keywords, category, country, device. There is nowhere in the system to store a user id, because we never wanted one.
15%, written on every impression
Publishers keep 85%, recorded per impression at serve time. No undisclosed spread between what the buyer pays and the seller earns.
Nobody serves on credit
Advertisers fund before they run, and billing checks that balance inside the transaction. Publishers are never owed money that does not exist.
For publishers.
Set your own floor
Your reserve price per placement. No bid below it ever clears, and unfilled requests tell you why — including when your floor is the reason.
Block who you like
Advertiser domains and categories you will not carry. A block is absolute — no bid is large enough to buy past it.
One tag, no layout shift
Reserves the slot before requesting, renders inside a sandboxed iframe, sets no cookies, and fails silently rather than breaking your page.
<div data-ss-placement="plc_…" data-ss-height="250"></div> <script src="/adx.js" async></script>
For advertisers.
Questions.
How is this different from Google Ad Manager or DoubleClick?
Three ways that matter. There is no cross-site identity anywhere in the system — targeting is contextual, coarse geographic and device class, and there is nowhere in the schema to put a user id. The fee is a single published 15%, written onto every impression row so publishers can audit it rather than reconcile a monthly summary. And advertisers prepay, so an impression is never served that the platform cannot pay a publisher for.
What targeting is available without cookies?
Page keywords and site category, country, device class, and specific sites or placements. Frequency capping works through a salted hash that is scoped to one campaign and one day, so it cannot be joined across campaigns or across days and resolves to no person.
How does the auction price impressions?
Second price with a publisher floor. The winner pays one cent above the runner-up, or the floor if there is no runner-up, and never more than their own bid. That means bidding your true value is always the right move — there is no shading game to play.
When do advertisers actually pay?
When a creative renders, not when an auction is won. The impression pixel fires from inside the rendered ad frame and carries a signed token, so an auction that never rendered costs nothing and nobody can bill an advertiser by guessing an id.
How do publishers get paid?
Your 85% share is recorded on each impression as it serves. When you settle, we transfer to your own Stripe account. The money is already on the platform — advertisers funded it before their campaign could go live — so a payout only has to be sent, never collected.
How do you stop someone monetising a site they do not own?
A site earns nothing until its domain is verified by an ads.txt line, which also serves as the public supply-chain declaration buyers check. Our sellers.json lists every verified publisher, so any impression can be traced to the entity that was paid for it.
