Questions

Something else? Write to us, a person answers.

Where does the data come from?

From the public ad libraries of Meta, Google and LinkedIn. We match each ad to a real company with its own website, and we count its ads every week.

Is the revenue real?

Nobody outside a company knows its real revenue. Ours is an estimate built from ad activity, shown as a range so you can see how sure it is.

How is this different from the Meta Ad Library?

The Meta Ad Library shows one advertiser at a time. SaaSpy shows every SaaS together, sorted by who is growing, with spend and revenue estimates next to each ad.

Do you cover mobile apps?

Yes. Web SaaS and mobile apps are both in the library, and you can filter by either.

How often is it updated?

About 1,400 companies a day, so 96% of the catalogue has been read again inside the last month. Every number carries the date we counted it, and a company we have not been back to says that instead of pretending.

Can I try SaaSpy before paying?

Yes. The free tools and a free account show real ads and real numbers, no card. When you take Pro you pay right away, and if it does not help you, you get your money back within 7 days, no questions.
