ABOUT WITHIII
Our Mission
At Withiii (pronounced Withy), our mission is to revolutionize the way people think about human interaction, leadership, and collaboration. Designed for and focused on the changing world of technological disruption and the transformation of human work, Withiii provides solutions to organizational and societal divisions and separations.
Those who lead corporate improvement and turnaround efforts often name oneness as a key slogan or aspiration. Similarly, governmental and community leaders call for unity in order to combat the challenges of our day. But slogans and aspirations don’t make it happen. People make it happen. Organizations and societies need leaders who invite and enable people to
operate as one - a phenomenon we call Convergence.
This is Withiii’s work. We enable increased levels of Convergence by helping to overcome divisions and break down silos that isolate, separate, and divide. We empower organizations to act, adapt, and grow as one cohesive unit. We help to build thriving communities that embrace diversity of every kind and transform in the process of inclusion and togetherness. This work increases engagement, agility, belonging, resilience, and productivity.
As a natural extension of our work, we seek to enable Convergence with those around us and work together with other renowned thought leaders and practitioners in the leadership, collaboration, culture change, and conflict resolution spaces. These thought partnerships drive better scholarship around collaboration and enable Withiii to bring the best of individualized solutions in its work with clients.
We work with in order to help you work with. Together is what changes the world.

Kathrin is an internationally recognized and accomplished management consultant and coach with a long and impressive track record of leadership and executive success in one of the world’s most ambitious and hard-charging Fortune 500 companies, Robert Half. Born, raised, and educated in Germany, Kathrin’s early interests and passions for languages, philosophy, and the arts stood in sharp contrast to the corporate career she was about to embark on. She received her degree in Economics from the University of Hamburg and a postgraduate certificate in International Business from Henley Business School in the United Kingdom.
Soon after joining Robert Half, she established herself as a top 5% consultant in the company globally and was first promoted to lead the operations in northern Germany before taking over responsibility for all of Robert Half’s recruitment operations across Central Europe. Due to her unparalleled success and her fully bilingual language capabilities, she was transferred to global headquarters in the United States, first as a Director for one of their key markets in the San Francisco Bay Area, and then as a Vice President on the east coast, becoming the company’s internal turnaround specialist and leading the transformation of multiple Robert Half offices and practices around the world.
After her successful leadership career, Kathrin decided to start her own consulting and coaching practice to bring her leadership and experience to companies both inside and outside the professional recruiting industry. During this time, she also received her ICF coaching certification and became a senior consultant for the Arbinger Institute, where she led global culture change initiatives. Her success with Arbinger led them to hire Kathrin as the company’s Director of International Sales and Development, while she continued to serve as a group facilitator, change consultant, and public speaker on mindset change for large international organizations.
When not working, Kathrin loves visiting museums, attending concerts, playing the piano, snowboarding down the steepest mountains, and riding her road bike for miles on end. And she golfs. If she has to.
