FrançaisWhere demand outweighs supply
How many competitors within a 5-minute walk, and how many potential customers each: residents and daytime workers.
For opening a shop in Paris
The right spot, with the proof.
Found a storefront? Check it before you sign. Pignon scores the address for your type of shop, explains every number and gives you a report your banker can read.
Official public data only · 23 types of shop · all of Paris
Chains have site-scouting teams. You have your shoes.
The data already exists: INSEE, the business register, property sales, transport. It is just scattered and unreadable. Pignon brings it together and explains it.
Chain pressure
A Paul or a Monoprix does not weigh like an independent shop. Pignon tells them apart, on the map and in the score.
The street’s history
How many shops of the same trade opened here, how many lasted three years, and why the others closed.
Paris is changing. So is your street.
A few census and civil-registry figures that Pignon follows neighbourhood by neighbourhood, and puts in every report.
68%
of Paris households have no car: a strong sign for neighbourhood shops.
22%
of employed Parisians walk or cycle to work, up from 15% in 2017.
−25%
fewer births in Paris between 2015 and 2025: family demand is moving.
−3%
fewer residents between 2017 and 2022, with big differences from one neighbourhood to the next.
Sources: INSEE, 2017, 2022 and 2023 censuses; civil registry 2015 and 2025. Pignon calculations.

Our principles
Every number explained
No score without its reasons. If a number cannot be explained, it is not shown.
Signals, not advice
Pignon informs your decision. It never tells you to sign.
Data at its true resolution
Crime is published per arrondissement, so it is shown per arrondissement. Estimates are flagged.
Hosted in France: the app and its data run on servers in Paris. Pignon does not keep the addresses you check.

Questions
Is this investment advice?
No. Pignon is a decision-support tool: it shows indicators from public data and the method that combines them. The decision stays yours, with your banker, your advisor and the landlord.
Do you know commercial rents?
No, and we say so: no open source publishes commercial rents. Pignon shows property sale prices (DVF), clearly labelled as sale prices.
Which cities are covered?
All of Paris: 20 arrondissements and about 990 neighbourhoods. The main sources are national, so other cities will follow.
Is the data up to date?
Each source has its own rhythm: the business register is refreshed weekly, the census yearly. Each source’s date is shown in the app and in the report.
Who is it for?
For founders of independent shops: a first or second shop, often after a career change. CCI and CMA advisors and banks are welcome too.
Where is the data hosted?
In France. The app and its database run on servers in Paris, and the address search goes through IGN’s Géoplateforme, the French public service. Pignon does not keep the addresses you check, and no account is needed to explore the map.
