Built on proof, not guesses. Founders who checked the market before they built.
“I'd been stuck on 'what should I build' for months. Sorted a niche by MRR, saw three small apps all scaling ads at once, and had my version live in five weeks.”
Priya Raman
Indie maker
“We pick two or three products a year for the studio. This replaced a week of spreadsheet research with an afternoon, and the ad library alone is worth it.”
Martin Keller
Founder, product studio
“Seeing real reach by country changed where I launched. Everyone in my category was spending in Spain and Italy, so I started there instead of the US.”
Kwame Mensah
Solo SaaS founder
“I use it to study creatives. Filter to ads that have been running for months and you know which ones actually make money, not just which ones look good.”
Mei Lin
Performance marketer
“I browse it like a menu of ideas. Every evening I save a few startups that are quietly making money, and one of them became the app I'm building now.”
Diego Alvarez
Growth lead
“Proof before code. I killed two ideas in a day because nobody was paying to advertise them, and doubled down on the one where five startups were.”
Sanna Lindqvist
First-time founder
Frequently asked questions.
Why look at ads?
A startup that keeps paying for ads month after month is making that money back. It's the clearest public sign an idea sells.
Why not Meta's Ad Library?
Meta shows one advertiser at a time, with no revenue or trend. We find the startups, estimate their MRR and rank their best ads.
What can I see for free?
Every startup's MRR, ad spend, reach, trend and category, plus its ad copy. Members see which startup is behind the numbers.
What do members get?
Every startup's name, website and logo, every ad's image or video, and a saved list for the startups and ads you care about.
Who is this for?
Founders hunting for their next idea, makers who want proof before they build, studios picking what to launch, and ad marketers.
Where's the data from?
Public advertising data. We find startups running paid ads, collect their ads and reach, and estimate their spend and revenue.
How fresh is the data?
Every startup is refreshed monthly, and new advertisers are added as they show up. Each one shows when it was last synced.
How is MRR estimated?
From ad reach and spend, with the same conservative assumptions for everyone. The numbers compare fairly rather than being exact.
Can I cancel anytime?
Yes, from the account menu. Membership is monthly with no contract, and you keep access until the period you paid for ends.
