Who are they?

Did you know that 54 million workers around the world spend more than 20% of their time manipulating data in spreadsheets ?
This is the major problem that YZR, a French start-up co-founded by two experienced professionals, is solving by offering companies an intelligent data standardization solution (via artificial intelligence), to say goodbye to this process that is rotting people’s lives and finally to take full advantage of the data of companies.
YZR has a very strong traction on the market, and a rapid development in France and internationally. Development which is still accelerating thanks to a recent “Seed” raising of 12 million from Orange Ventures!

Our values :
• No bullshit jobs : we solve a real problem.
• Immediate take off : YZR goes very fast, and careers too.
• No baby-foot, no harassment : There is no foosball at YZR, and everyone is happy to work there.
• Safe place to work : inclusion, equality and justice are not empty words at YZR
• Healthy workplace : we have better things to do than micromanager.
