Our visit at Ledger



Ledger has several buildings to organize the different tasks

At the « pôle innovation », we listened to a conference about Ledger and its history.

We visited the production line and the rooms for relaxing, having coffee, playing babyfoot…

The visit of the company was in English.

Thank you to Yamileth and David Balland for your welcome!

« The visit was good. It was very interesting for people who are interested in new technologies. »

Ledger is a start-up that makes hardware wallets (a flashdrive that allows to store and secure cryptos like bitcoins)

They make products that are both for people and companies.

Ledger has lots of partners and many companies invest in their products.

Ledger has evolved very quickly and the income has increased a lot. In the future, the production site of Vierzon will be bigger. They will move to another building this summer.

At Ledger, the different parts of the hardware wallet are handmade. There are between 10 and 12 employees on the production line.


Thanks to the « workplace » facility, Ledger takes care of the employees’ well-being.  They want them to feel well at work to be more productive. They can relax and play babyfoot in some spaces. They will soon have a swimming pool as well.


Employees have different profiles but they all need to be creative and have a good level of English as well as being interested in new technologies.
