Jean-Sébastien Wallez
Hi! I'm Jean-Sébastien, a French entrepreneur currently living in Paris.


Boost your growth


There are two things that I can help you with:

1. Making your product addictive

I believe that addiction is the new growth and that almost every company, either B2C or B2B, will soon look for ways to add some form of addiction to their products to unlock a new powerful growth engine.

2. Bringing new users at almost no cost

In a world where communication is free, paying thousands of dollars per month in ads is not the only option. With the right incentives and UX patterns, your own users can become your best distribution channel.
