What counts as an ad space?

A shirt, a website, a car, a wall, a storefront, even a gadget. Anything people can see.

A forehead
example
Andrew Fischer sold his for $37k in 2005. Yes, really.
A house wall
example
Your brand, painted on the side of a building.
A car
example
Parked, driving, stuck in traffic. It is seen all day.

If people see it, someone can rent it.

Got space people can see?

Put it up for rent. Set what you are offering and what it costs, send the link to the sponsor already in your DMs, and get paid when the placement actually runs. About a minute, no wallet until someone pays.

Sell your space
Promise it · Run it · Prove it · Get paid

A booking is only complete when the ad runs.

Rentl holds the money until there's proof the placement happened. No wondering whether the ad ran or where the money went: you keep a clear record of what was promised, what was delivered and what was paid.

  1. Find a space

    Browse advertising space listed by people who have something worth showing.

  2. Book it

    Pick the placement you want and pay the price the seller set. No haggling in DMs.

  3. The money is held

    It leaves the sponsor and goes nowhere. Neither side can touch it yet.

  4. Run the ad

    The seller puts the agreed placement live, exactly as promised.

  5. Prove it ran

    The seller uploads proof by the deadline. The sponsor sees exactly what was delivered.

  6. Get paid

    The sponsor confirms, or after 48 hours it is released on its own. No proof in time and the money goes back.

It worked.

Toni on stage at Superteam Balkan Demo Day in Belgrade, wearing the auctioned Jurassic Finance t-shirt in front of the audience, with the Rentl pitch slide on the screen beside him.
Superteam Balkan Demo Day · Startit Centar, Belgrade

22 hours on a bus. No sleep. Ten hours in Belgrade.

I auctioned the front of my shirt, the back of my shirt, and a slide in my own pitch deck. Then I walked on stage at Superteam Balkan's Demo Day wearing the product, in front of 100 people in the room and 2,300 watching live.

30 teams. Judge's Honorable Mention.

The shirt was never the point. The point was finding out whether people will actually pay for a surface. They will.

Advertising doesn't have to be on a billboard.

It can be on a shirt.

What is Rentl?

Rentl is a marketplace for advertising space.

People with space list it, and sponsors book it and get their ad in front of real people.

What can I sell on Rentl?

Anything that can legitimately carry an ad.

A shirt, website, car, storefront, wall, event, screen or any other surface people can see.

I have a space I want to sell. How does it work?

List it: say what it is, mark the places an ad can go, price each one and say what you will do.

When someone books a place, run their ad as agreed and upload proof that it ran.

How do I buy advertising space?

Browse the listings, find one that fits what you want to promote, pick the places you want and upload your logo.

You pay the listed price, and the money is held until the seller proves the ad ran.

How are spaces priced?

The seller picks for each place: a fixed price, or an auction.

At a fixed price, you see the price before you book and that is what you pay. In an auction, the place goes to the highest bid when it ends.
