How Mianos works
Advertising space,
paid through escrow.
A marketplace for real-world and digital advertising spots — billboards, windows, newsletters, podcasts, wrapped vans. Buyers and sellers agree on a price, then funds are held safely until the ad is live.
For buyers
From finding a spot to seeing your ad live — four steps.
- 01
Browse or search
Filter by city, audience, format, or budget. Every listing has transparent packages and shows the typical setup time.
- 02
Make an offer
Pick a package, pick a start date, send an offer. The seller can accept, counter, or reject. You negotiate until you close.
- 03
Pay securely into escrow
Card or Apple Pay via Stripe. Mianos holds the funds until the seller delivers proof of placement. Your money is safe.
- 04
Approve or dispute
Once the ad is live, approve the order to release payment — or open a dispute within 7 days if something's off. Reviews close the loop.

List in minutes
Name your space, add photos, define 1–3 packages with durations. You can draft as a guest — we'll only ask for your email at the publish step.

Respond to offers
Counter-offers keep buyers engaged. Typical close rates are highest when bargaining is on.

Deliver proof, get paid
Post proof photos or screenshots when the ad is up. The buyer approves; funds land in your Stripe account. Auto-release after 7 days if the buyer doesn't respond.
