After successfully launching his career at Booz-Allen & Hamilton strategy consulting firm, Krister's father tapped him on the shoulder and asked him to move back to St. Louis to apply his knowledge and experiences to help the family business. Ungerboeck Software had just celebrated its 12th anniversary and needed some fresh ideas and new leadership techniques.

Within 3 years, Krister had helped turn around the 14 person business and grow revenue 250%. Over the course of the next 20 years, Krister and the capable team at Ungerboeck Software grew the company over 3,000%. The team added customers in over 50 countries served out of offices in St Louis, UK, Germany, France, Australia, Hong Kong and China.

During his time as CEO, the company won 5 consecutive Top Workplace awards and had employee turnover 50% lower than the industry average.

From 2001 - 2007, Krister moved to France and Germany to drive growth in Europe and the Middle East (EMEA). During that period, EMEA accounted for nearly 75% of the company's revenue growth.

In 2016, Krister executed a unique exit strategy that involved retaining 100% family ownership, while passing the torch to an exceptional non-family team that he personally recruited in 2014 and 2015. As part of the leadership transition, he formed a Board of Directors and recruited external Directors, a new CEO and VP Finance to guide the company going forward.

Ungerboeck Software continues on to great success under non-family leadership as one of a handful of large, 100% family owned software companies in the US.
