Our mission: Help you success yours

Reconcile Human Resources and Operations

Through their mutual experiences in human resources and management, our co-founders Anne-Sophie and Gautier realized how difficult it is to maintain an efficient communication on company’s strategic objectives and how to achieve them.


Moreover this communication is translated in long, complex and rigid processes… Here is how Javelo is born: reconcile HR and operations with a simple, dynamic tool facilitating continuous performance management.

Our values


We believe that kindness is the key of success. This kindness is the heart of our product, help each employee improve himself

deployment of their strategies by supporting them in their transformations

Ambition and result oriented culture

Trust each other is essential to success together. We design our product with this in top of mind, to let you reach your goals
