Competitor research for people who do not have a research team
StoreLenz tells people who run online shops what the shops they compete with are doing. This page is about why it exists and how it works — including the parts we cannot do, which we think matter just as much.
Why it exists
A large retailer can pay people to watch the competition. Somebody running one or two shops usually cannot, so they do it by hand: opening a rival's website on a Sunday evening, trying to remember what the price was last month, and finding out about a sale from a customer who mentions it.
None of that is a skill problem. The information is public — it is sitting on the shop's own website, where anyone can read it. It is just spread across hundreds of pages and it changes while you are not looking. A computer is good at exactly that and a person is not.
StoreLenz exists because of a gap its founder kept running into: doing real, deep research on a competitor's store was slow and difficult, and in business the quality of your decisions comes down to the quality of your information. Wise decisions need real research behind them, not guesswork.
How it gets its information
We read what a shop publishes to everybody. Its pages, the product list it makes available to any browser, and the files it serves to help search engines find it. Everything StoreLenz shows you, you could have looked up yourself with enough evenings.
We never sign in to anyone's shop. We do not ask you for a shop's password, we do not install anything in anybody's shop, and we have no way of seeing orders, customers or payments. There is no private door, and we are not looking for one.
We read politely: at a normal pace, and following the instructions a website publishes about what automated visitors may look at. A shop owner who would rather we left them alone can write to us and we will deal with it.
Why we say what we cannot do
Nobody can read a shop's accounts from the outside. Anyone who shows you one exact revenue figure for a business they do not own is guessing, and hiding that they are guessing.
So when StoreLenz estimates something, it gives you a range, a label saying how confident it is, and a sentence explaining what the estimate was built from. When the information is not there, it says so instead of filling the gap with something plausible.
That costs us the occasional sale to somebody who wanted a confident number. We would rather lose it there than have you find out later that the number was never real. The page about what it does lists the limits in full, next to the things it does well.
Who is behind it
StoreLenz is run by a small team, based in Portugal.
The product has been running on real shop data since September 2026, and parts of it are still being finished. Where something is not ready, the site says so rather than leaving it out and hoping nobody notices.

Try it on a shop you already wonder about
The trial lasts 7 days and asks for no card. If it tells you nothing you did not already know, that is a useful answer too — and we would like to hear it.
