Why ads tell you where the money is
Nobody keeps paying for ads that do not bring customers. So when several companies in a niche advertise for months, buyers are there and they pay. That is proof of demand you cannot get from a survey.
SaaSpy counts the live ads of every SaaS company on Meta, Google and LinkedIn every week. A company is scaling when it runs more ads than a month ago, and pulling back when it runs fewer.
How to read the verdict
Open, heating up: few companies advertise and more of them are scaling than pulling back. Demand is proven and the room is still there. The best place to look first.
Competitive: a real market with a fair number of players. You win here with a sharper angle or a smaller segment.
Crowded: 40 or more companies advertise. Customers buy, but ads cost more. Go narrower: one job, one type of customer.
Open, quiet: few companies and no growth. Either the niche is early, or the ads do not pay. Look at how long their ads run before you decide.
From a niche to an idea
Pick an open niche, then type your idea into the Competitor Ads Checker with the website of the strongest company there. Their longest-running ad tells you what customers answer to; the gap is what nobody says yet.
Questions
What is a good SaaS niche?
One where companies already pay to advertise (so customers buy), with few enough players that you can stand out, and with more companies scaling their ads than pulling back.
How does SaaSpy find these niches?
It tracks the live ads of every SaaS company on Meta, Google and LinkedIn every week and groups the companies by what they sell. The counts on this page are updated daily.
What does 'scaling' mean here?
The company runs more ads now than a month ago. Companies scale ads that bring customers, so scaling is a sign the niche pays.
Does a crowded niche mean I should not build there?
No. It means demand is proven and competition is high. You need a narrower angle: one customer type or one job the big players do badly.
Can I see the companies in each niche?
Their names, ads, spend and revenue estimates are on SaaSpy Pro. You can also check any single company for free with the Competitor Ads Checker.
