    Tamahris team

    Tamahris team

    Tamahris was founded in 2013 by Geert Van Gucht and Vincent van Lennep, two experienced HR consultants, sharing a common vision of commitment and innovation for their clients.

    In a short time, the Tamahris team has grown and now has 19 dedicated and passion-filled professionals, with diverse backgrounds, covering 8 languages. They bring a wealth of experience in supporting transformation projects from small businesses to large international organizations.


    Tamahris founders



    Geert is a seasoned HR professional with over 30 years of experience, having had several operational and project management roles in HR and IT with a large financial organization.
    Geert is used to working in a complex organization, with multiple structures and cultures. He is hands-on and action oriented, and he is able to cover both strategic and operational issues. He loves to lead project teams to achieve incredible results, through coaching them with inspiring leadership. Geert is passionate to make HR better through technical innovation, by capturing the innovative potential of SaaS tools, which, in turn, help HR leaders to deliver their Talent and Performance management strategy.
    Over the last 10 years Geert’s focus has been on HR organizational change, tools optimization and HR technology. Most recently, he has been responsible for a major HRIS transformation program for a large financial group with over 180 000 employees in over 80 countries. Through this program the corporate ERP structure has been replaced by a modular and flexible approach, implementing the Cornerstone solution for Learning, Performance and Career management.



    In his career, Vincent’s drive has always been to adapt the latest technologies to HR requirements, starting with self service applications in the early 2000s, which opened the ERP backbone to employees and managers with the advent of web technology. He now specializes in providing unique solutions for complex and large organizations by building the appropriate technology for their HRIS strategies. As his career evolved in international consulting, Vincent had the opportunity to work for large European companies across the continent at a variety of business, enriching his knowledge of HR tools, processes and organizations.
    Before launching Tamahris with Geert, Vincent worked for a major financial institute, which gave him the opportunities to further develop his skills from the inside of an organization. From this vantage, he was able to further refine the skills needed to develop a project, launch it and validate extremely ambitious and modern HRIS architecture.
