About
Who is behind beltup
beltup is published by Kernel Ops SASU, a French company I founded and of which I am the sole shareholder.
My name is Clément Rat. I am a Lean Six Sigma Black Belt and I build beltup myself. There is no team behind it: when you write to beltup, I am the one who replies.
I built this tool because I prepared for these certifications and did not find what I was looking for: questions close to the exam, marking that explains, and a publisher you can reach.

What I commit to
A reply within 48 working hours. Write to contact@beltup.fr and you will get a reply from a person, not a form.
A reported mistake is dealt with. If a question looks wrong or ambiguous to you, report it: I correct it or I explain why it is right. Either way, you get a reasoned reply.
No made-up figures. You will not see a pass rate on this site until I have the means to measure it honestly. The day I publish one, the method will be published with it.
What beltup is not
beltup is not a certification body. It trains, it awards no Lean Six Sigma certification and is not affiliated with any certification body.
I do not promise you will pass your exam. A practice tool improves your chances, it does not guarantee them — and no one should tell you otherwise.
Nor does beltup replace field experience. A project carried out, coached by someone experienced, is worth more than any quiz. The two complement each other, they do not substitute for one another.
