the COSS solution

A scientific, user-centric approach that enables you to reliably and efficiently measure soft skills.

Created in 2017 by a serial entrepreneur, an HR Director and a Dr in Human Resources, the 5Feedback app offers to both students and professionals the opportunity to measure and certify their soft skills.

As pioneers, the group was convinced, based on their research, experience and expertise, that soft skills are key to unlocking everybody's greatest potential and talents, especially when their professional or academic careers are equivalent to those of other people.

Placing people at the heart of businesses:

Recruit personalities, give value to soft skills and develop competencies, this is a win-win situation for the company, the employee and the student. After receiving various start up awards (Enedis, SAP, ....), the application is set to revolutionize the evaluation of soft skills and is now a play an important tole in this new era in Human Resources.

When algorithm and ethics work together:

Implemented in several large groups, across 25 countries and used by more than 40,000 people, the App is based on a technology that ensures the reliability of the feedback in order to guarantee the assessments. With more than 40,000 users and a powerful and ethical algorithm that checks both the quantity and the quality of feedback received, this application guarantees the reliability of its certifications.
