Olivier is the creator and inventor of ROK3 (a patented innovation) that provides endless opportunities for integrated collaborative management (SI and business applications). He is also founding President of ROK Solution. His unusual career in management in many businesses areas (Consulting, IT, marketing and communication, accounting, factories, etc.) both in France and internationally (Europe, USA, China, Israel) convinced him of the virtues of a holistic approach to organization. This vision can be seen in the solution and in the make-up of the management team.

Holder of a Masters in Management of Organizations and a Master II in Internal Audit, and after 2 years of operational experience in internal control, Nicolas joins the ROK team in its “pioneers” phase.

Today he accompanies customers in their appropriation of the incredible capacities of the ROK platform. Passionate about the early phases of co-design with customers, the ROK platform has no secrets for him!

Graduated from a master II in Management, Sophie joined the adventure in 2019 in order to support companies in their digital transformation. As guardian of customer success, she is at the core of the interactions between marketing, commercial, support and tech. Her mission is to make the client’s experience as smooth and simple as possible.  Your success is her success.



Holder of a DESS engineering degree SI from Pierre et Marie Curie University, Grégory has a solid experience with software publishers experts in the measurement of quality of service and financial consolidation; he joined ROK in 2011 and since 2014 he has been leading the development team.

Grégory has the art of knowing how to translate the vision expressed by Olivier into functionalities in the architecture of the platform. Struck to the stress of go-live, his natural phlegm combined with his decline on the technological choices allow him to lead his team calmly.

Olivier made a name for himself at age 17 by winning with Nathan and Michel Bussac the tender “IT for all” that marked the young minds of the time. He was involved in the early stages in the history of Business Object, Capsule and also Réputation VIP and joined the ownership team at ROK Solution to head R & D in 2010.
