Co-Founder | Head of Executive Coaching, Business Development, and Operations

Prior to founding Withiii, Jim was a longtime managing partner of the Arbinger Institute, which grew into one of the leading leadership consultancies in the world under his direction. He is the (principal) author of one of the bestselling leadership books of all time, Leadership and Self-Deception, as well as the bestselling book on conflict resolution over the last decade, The Anatomy of Peace. Other bestsellers include The Outward Mindset and many other books. Along with Brené Brown, Patrick Lencioni, Simon Sinek, and John Maxwell, he is a contributing author to Ken Blanchard’s bestselling book, Servant Leadership in Action. Jim’s publications have sold many millions of copies around the world.


Over his nearly three decades as a thought leader working with corporate and governmental leaders, Jim has developed a reputation as one of the world’s great innovators in the areas of leadership, culture change, conflict resolution, communication, and interpersonal connection. He has a unique ability to grasp complex ideas and translate them into elegantly clear models and applications. He is a regularly featured speaker at trade and corporate conferences and has mentored leaders and trained workforces of some of the most well-known organizations and brands in the world. His work has been instrumental at Apple, Microsoft, Google, IBM, Boeing, Airbus, Deutsche Telekom, T-Mobile, Harley Davidson, Nike, the NFL, Shell, Zurich Financial, McKinsey and Company, and Baine Capital, among many other companies, as well as within the White House, Treasury, and most branches of the federal government of the United States.


Jim has degrees in economics and philosophy and is a graduate of Yale Law School. After graduating from Yale, he joined the California Bar and practiced law at Latham and Watkins. He is a past member of the Yale Law School Executive Committee and serves on the Board of Advisors of the J. Reuben Clark Law School at Brigham Young University, where he also teaches as an adjunct professor on the topic of law and leadership. He is the recipient of multiple awards on peacebuilding.


In his spare time, Jim enjoys the outdoors. He is an avid cyclist and a longtime but decidedly average golfer. He is usually reading about five books at a time and is fascinated by all the goodness and wisdom in 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 Europe, 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 Socioeconomics from the University of Hamburg and a postgraduate certificate in International Business Administration 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 services 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.


Before co-founding Withiii with Jim, Kathrin led Arbinger's international business as Managing Director of the Germany-based international entity and as the company's head of international expansion, while she continued to serve as a group facilitator, change consultant, and public speaker on mindset change for large international organizations.

When not working or training for her next triathlon, Kathrin loves visiting museums, attending classical concerts, playing the piano, and riding her road bike for miles on end. And she golfs. If she has to.

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.

The world needs 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.
