Why are all indie hackers selling ad spaces now?

Are indie hackers really all selling ad space now?

A lot more indie hackers are selling ad space right now, but the boom is concentrated in directories, launch sites, leaderboards and other products built around getting attention.

TrustMRR currently tracks 205 websites in its advertising-platform category, with about $114,000 in verified revenue over the previous 30 days. The more revealing number is buried inside the ranking. Among the first 30 businesses shown when we reviewed it, 14 had been created within the previous ten days. Those 14 had already generated about $26,400 combined, around 23% of the revenue of the entire 205-site category.

Look at the products and the pattern gets even clearer. BrandMyMac sells space next to the Apple logo on a founder's laptop. Warmap.lol sells countries to brands. SiliconCity sells branded plots in a virtual city. ECOMBID lets ecommerce companies bid for leaderboard positions. XME.lol does something similar for X profiles.

So yes, something unusual is happening these days. But we are mostly seeing founders turn attention-heavy websites into places where other founders can buy visibility. Conventional SaaS products are not suddenly filling their dashboards with banner ads.

Recently launched project	Age when reviewed	Verified 30-day revenue
BrandMyMac	4 days	~$7,900
Warmap.lol	9 days	~$7,500
SiliconCity	7 days	~$2,200
BrandMyLaptop	3 days	~$2,000
ECOMBID.IO	6 days	~$1,400
WorldMap.lol	8 days	~$1,200

Why did indie hacker ad businesses explode so suddenly?

The current rush started because several founders showed, almost back to back, that a small free product with a lot of attention could make serious money from advertisers.

TrustMRR was an early example. Marc Lou launched the revenue database for founders and quickly started selling a limited number of sponsor positions. The initial slots went for $299 per month, then the price climbed as demand increased. Marc later reported roughly $18,000 in sponsor MRR after filling the available inventory.

Pieter Levels pushed the idea much further with his browser flight simulator. Instead of relying mainly on players buying virtual items, he sold branded objects inside the game for thousands of dollars. The game reached about $87,000 MRR within 17 days according to Levels' public updates, with in-game advertising doing much of the work.

Then Outbid.lol arrived and made the advertising mechanic itself entertaining. Brands paid to rank above each other publicly. The higher the bid, the higher the position.

Those three examples landed in a founder community already obsessed with distribution. Suddenly there was a visible alternative to the usual equation of “build SaaS, find subscribers, collect $19 a month.” If a free site attracted the right crowd, a handful of advertisers could sometimes be worth hundreds of paying users.

Did TrustMRR prove indie advertising could work before the Outbid craze?

TrustMRR gave indie hackers one of the clearest recent examples of a free founder product turning a small amount of ad inventory into meaningful recurring revenue.

Marc Lou initially opened sponsor positions at $299 per month. Demand came quickly enough for him to raise the price several times, eventually reaching $1,499 for some monthly placements. In his launch retrospective, he reported $20,378 in revenue within three days and later said all 20 advertising positions had been filled, representing roughly $18,380 in monthly recurring revenue.

TrustMRR is much bigger today. Its own verified profile currently shows about $39,500 in revenue over the previous 30 days, more than $300,000 in lifetime revenue and around $20,500 in MRR. We should not call all of that advertising revenue, because TrustMRR now makes money from several products including marketplace services and paid visibility.

That evolution is actually more interesting than the original sponsor launch. Advertising gave Marc a way to monetize the audience quickly without putting the database behind a subscription. Once enough founders were visiting the site, he could sell them other things too.

For indie hackers watching from the outside, the lesson was easy to understand: you do not necessarily need thousands of paying users when a much smaller number of companies will pay hundreds or thousands of dollars to reach the people already using your product.

Why did Outbid.lol make paid visibility go viral?

Outbid.lol made advertising feel like a game, and that simple change turned a boring business transaction into something founders wanted to watch, share and copy.

Outbid was built in a few hours and launched less than two weeks ago. The rule could hardly be simpler: pay more than the company above you and you move higher on the public leaderboard.

The site currently shows more than 1.38 million visitors. Its top position has reached $17,000, while the second position sits at $16,000. Outbid's founder says at least ten copycats appeared during the first 24 hours.

The copying has accelerated since then. Outbid.fyi, an independent tracker dedicated to the trend, currently follows about 350 similar boards and puts their combined tracked earnings around $331,000.

The public bidding changes the psychology completely. A normal sponsor pays $500 and receives a banner. On Outbid, paying $500 changes the ranking that everyone else can see. Another company can then pay more, which gives the first company a reason to bid again.

Each payment becomes part of the website. Big bids create screenshots. Screenshots bring visitors. Visitors bring more bidders. That feedback loop explains why this particular form of advertising spread much faster than another founder quietly adding a “Sponsor us” page.

Did Pieter Levels show that almost anything can become ad space?

Pieter Levels showed that these days even a tiny browser game can become valuable advertising inventory if enough people are paying attention to it.

Levels' multiplayer flight simulator started as another fast AI-coded experiment. Once the game took off on X, he began putting companies inside the virtual world through branded blimps, billboards, terrain and other objects.

Some placements reportedly sold for around $5,000 per month. Within 17 days, Levels said the game had reached roughly $87,000 in MRR and a $1 million annualized run rate.

The interesting part was the gap between what players were willing to spend and what companies were willing to spend. Early public revenue updates showed advertising bringing in many times more than purchases of virtual planes.

That changes how a founder looks at a free product. A game does not always need millions of players buying skins. A popular tool does not always need a premium plan. Sometimes the people watching are worth more to another company than the product itself is worth to each individual user.

We can see that thinking spreading now into laptop stickers, virtual maps, digital buildings, rankings and other strange formats that barely resemble traditional banner advertising.

Are these indie hacker ad businesses even selling normal ads?

Most indie hacker ad businesses today are selling paid visibility rather than conventional banner advertising.

The formats vary a lot. Uneed sells a $297 monthly site-wide ad position and $399 newsletter sponsorships. OpenAlternative sells sponsorships and featured listings. Outbid-style sites sell position directly through bids. BrandMyMac auctions physical sticker space. Warmap lets brands buy countries on an online map.

From the buyer's point of view, the distinction barely matters. The company pays money because it wants to appear in front of a specific group of people.

The trend is much bigger than a simple resurgence of banner ads. Founders have started treating almost any visible part of a product as inventory.

A directory result can be inventory. A newsletter can be inventory. The top of a leaderboard can be inventory. A virtual planet can be inventory. Even the back of someone's laptop can be inventory.

Once you use that broader definition, the current wave makes much more sense.

Why are indie hackers paying for all these ads?

Indie hackers are buying these placements because many of them can build a product now but still have almost nobody looking at it.

We found unusually clear evidence in an analysis of businesses advertising on Outbid. LinkDR reviewed 828 builder websites on the leaderboard after removing large established platforms. About 61% had a Domain Rating below 10, while 543 of the 828 had no measurable organic search traffic.

The spending was also tiny for most buyers. The median bid was only $5, and 617 businesses had spent $10 or less.

That looks much more like founders trying to get their first bit of distribution than mature companies running normal advertising campaigns.

Uneed's current advertiser pitch confirms who this market is built around. The site explicitly sells access to founders, indie hackers and early adopters. Its audience is attractive to another SaaS founder because these people actually try new software, launch products and buy tools.

There are now thousands of small products competing for the attention of roughly the same founder audience. That creates a natural market: one indie hacker has the product, another has the audience, and a few hundred dollars can connect the two.

What LinkDR found among 828 Outbid advertisers	Result
Domain Rating below 10	61%
No measurable organic search traffic	543 sites
Median bid	$5
Businesses spending $10 or less	617
Share spending $10 or less	~75%

Why do directories work so well with ads?

Directories work especially well with advertising because the visitors come to discover products and the companies being discovered are willing to pay for more visibility.

OpenAlternative is a good example. Piotr Kulpinski built the original site as a directory of open-source alternatives. It eventually reached a large search audience, and he now reports about $6,500 in monthly revenue from the project. Roughly 65% comes from ads and sponsorships, with the rest coming from featured listings.

That puts advertising-related revenue around $4,200 per month.

Uneed has reached a similar point from a startup-discovery angle. Its advertising page currently reports more than 90,000 monthly visitors and 22,000 newsletter subscribers. The $297 monthly site-wide ad position is sold out. Newsletter sponsorship costs $399 per issue, and several upcoming issues are already booked.

The economics are attractive because the reader can keep using the directory for free. Charging every visitor $10 would probably shrink the audience considerably. Charging a software company $300 to reach those visitors barely changes the experience for everyone else.

At $20 per month, a SaaS company needs around 210 active subscriptions to match OpenAlternative's estimated $4,200 monthly advertising revenue. A directory can reach the same amount with a much smaller number of advertisers.

That does not make advertising easier. OpenAlternative had to build the audience first. But once the audience exists, selling access to it can be much more efficient than asking every visitor to become a customer.

Product	Current audience signal	Current ad economics
OpenAlternative	Large search-driven tech audience	~65% of ~$6.5K monthly revenue from ads/sponsorships
Uneed	90K+ monthly visitors	$297 monthly main ad, currently sold out
Uneed Weekly	22K+ subscribers	$399 per sponsored issue
Adventory	13 publishers	$4 per 1,000 impressions for current customers

Why don't indie hackers just use Google AdSense?

Direct sponsorships can pay far more than AdSense when the publisher has a small audience that advertisers really want.

Piotr Kulpinski ran a useful real-world experiment on one of his tech sites. The site had roughly 100,000 monthly organic visitors. AdSense had once generated around $800 per month but later fell to about $200 even though traffic remained similar.

He started approaching relevant companies directly.

Six months later, he reported eight regular advertisers generating about $3,000 per month. That was 15 times the $200 AdSense level. Piotr estimated that his effective CPM had jumped from around $0.50 to more than $30, and more than 80% of the advertisers were staying month to month.

A generic ad network mostly sees pageviews. A company selling developer software may see 100,000 technology visitors who are exactly the people it wants to reach.

The second audience is obviously worth much more to the right buyer.

The indie advertising trend currently leans heavily toward direct sponsorships, featured positions and fixed placements. Founders want to charge for the quality of their audience rather than let an ad network decide what every thousand views are worth.

Can indie hacker ad revenue actually become recurring revenue?

Yes, direct sponsorships can become surprisingly recurring, although the newest pay-to-rank sites still have a lot to prove.

Piotr Kulpinski's experience is useful here because he reported more than 80% month-to-month retention among his direct advertisers. Uneed is also selling repeated monthly and weekly inventory, with its main monthly slot sold out and multiple newsletter issues booked ahead.

Those businesses have something close to recurring ad revenue even if the contracts are technically renewed one placement at a time.

Pay-to-rank businesses have weaker visibility into future revenue. A site can collect $20,000 during a viral launch week because companies are competing for position, then struggle to produce another $20,000 once people stop talking about the leaderboard.

This distinction gets blurred very easily on X. $10,000 of sponsorships that advertisers renew every month and $10,000 of one-time competitive bids produce the same revenue screenshot. They do not create equally durable businesses.

For now, the recurring side of indie advertising looks much more convincing on established directories, newsletters and communities than on the newest leaderboard clones.

Did AI coding make Outbid clones too easy to launch?

AI coding has compressed the Outbid copy cycle so much that the market is already crowded only days after the original went viral.

Outbid itself was built in a few hours. Its founder reported at least ten copies on day one. The independent Outbid.fyi tracker now follows around 350 boards.

That speed would have been much harder to imagine during earlier indie hacker cycles. A founder once had time to notice a successful business, understand it, build a competitor and launch weeks or months later. Now a visible mechanic can have dozens of working copies before the original founder has finished posting the launch results.

OpenAlternative experienced a slower version of the same problem. Piotr Kulpinski has talked publicly about seeing repeated copies of his directory once AI coding made it easier to reproduce. He eventually responded by selling Dirstarter, a boilerplate for building similar directories, which itself grew into another meaningful source of income.

There is an obvious consequence for today's ad-site boom. The code behind a leaderboard, directory or map is becoming cheaper every day, while the amount of attention available to all those sites does not increase nearly as fast.

That is already making distribution the harder part of the business.

Are Outbid-style ad sites already getting saturated?

Yes, the Outbid-style market already looks heavily saturated even though the trend is extremely young.

Hundreds of boards are now chasing the same basic pool of startup advertisers. The revenue gap between the winners and the long tail is huge.

TrustMRR currently shows several fresh advertising projects making thousands of dollars, including BrandMyMac and Warmap. Further down the same ranking, recent projects are sitting around $395, $377, $302, $231 or $216 in verified 30-day revenue. Others have barely made anything.

We see a similar gap across the broader copywave. The original Outbid has attracted more than a million visitors and five-figure bids for its highest positions. Many clones have only a few bids.

That is exactly what we would expect when the feature itself is easy to copy. Every new clone adds another place where a startup can advertise, but it does not create another startup with an advertising budget.

Supply can therefore explode much faster than demand.

The best chance for a newer entrant is probably to own a specific audience or come up with a genuinely different distribution loop. Launching the 351st generic pay-to-rank board gives advertisers very little reason to care.

Does selling ads mean indie hackers are giving up on SaaS?

No, indie hackers are mostly adding advertising where charging every user would make less sense.

Several of the strongest examples mix revenue models. Uneed sells launches, directory submissions, reviews, premium placements and sponsorships. OpenAlternative combines sponsorships with featured listings while its founder also sells Dirstarter separately. TrustMRR now earns money from several products beyond its original sponsor slots.

That behaviour looks pretty rational. Founders are matching the way they charge to the type of product they built.

A private analytics SaaS used by 200 companies has obvious customers: the 200 companies using the software. A free startup directory with 90,000 visitors has a different asset. The visitors want free discovery, while companies want better access to those visitors.

Forcing both businesses into the same $19-per-month subscription model would make little sense.

The recent ad rush therefore tells us more about the types of projects indie hackers are building lately. Free directories, databases, launch platforms, little games and viral experiments are easier to monetize through businesses seeking attention than through casual users seeking content.

Has distribution become more valuable than software for indie hackers?

For many small internet products today, distribution is becoming scarcer than the software itself.

OpenAlternative was built in 48 hours. AI coding tools now let one founder build a usable directory, leaderboard, browser game or small SaaS in an afternoon or a weekend.

Getting 100,000 relevant people to care remains much harder.

That gap changes where the economic value sits. If 50 founders can build roughly the same directory, the code has limited scarcity. The directory with the search rankings, newsletter list, reputation, backlinks and returning visitors owns something the other 49 cannot reproduce with another Claude Code session.

Advertisers pay for that difference.

The same logic explains why a free site can occasionally earn more from ten sponsors than another product earns from hundreds of subscribers. The sponsor is buying access to an asset that remains genuinely hard to manufacture: attention from the right people.

This also explains why most fresh ad businesses will probably fail. Adding a checkout button and an ad slot takes almost no time now. Building an audience that makes somebody want to click that button is still difficult.

Why are all indie hackers selling ad spaces now?

The claim is mostly true for the current wave of founder-facing attention products, but exaggerated for indie hacking as a whole.

Indie hackers are selling more ads these days because the economics have changed in a very specific way. Software has become dramatically easier to produce, thousands of tiny startups now need distribution, and a relatively small number of founders control audiences that those startups desperately want to reach.

That creates a marketplace almost by accident.

The founder with no audience pays for attention. The founder with the audience sells it. A directory, game, newsletter, leaderboard or free tool becomes the place where they meet.

The freshest numbers suggest this is more than an X fad. TrustMRR currently tracks 205 advertising platforms doing roughly $114,000 in verified 30-day revenue, and a large chunk of the visible new revenue comes from projects created only days ago. At the same time, hundreds of Outbid-inspired sites have appeared almost immediately.

The second number is also the warning.

Making an ad product is now so easy that the market can become crowded before most founders have made their first dollar. There are already far more websites trying to sell visibility than there are websites with genuinely valuable attention.

So the founders likely to keep making money from ads are the ones who would still have something valuable if the ad slot disappeared tomorrow: an audience, search traffic, a newsletter people read, a community people return to or a product that keeps going viral.

The current gold rush is about ad space. The durable business is still about owning attention.
