I was introduced to Gregor through an academic program at Columbia. I had my doubts over continuing with the program as the academic piece alone was not bringing much value in my opinion. This all changed when I met Gregor and I was able to benefit from his point of view in many different areas. Gregor has helped me improve my communication skills, provided me a lot of input in terms of how to be more emotionally intelligent, guided me through some potential pitfalls i might run myself into and much more. While my program at Columbia is going to end soon, i will remember and try to recall many of Gregor's teaching as they come from a deep well of knowledge and experience. Gregor champions many domains including technical skill, management skill, his vast experience in outstanding organisations and as many leaders a great intuition for what's the next big thing. I will surely miss my meetings with Gregor but will always be thankful for his time and patience in helping me improve my skill.

With Gregor's advice and mentorship, we improved our operating margin by close to 35% within a month. He helped focus our technology efforts on the exception paths that were hurting our operating margin most. This dissection of our business led to us rebuilding our projections, rapidly improving our P&L, and ultimately put Latchel in a position to breakeven much faster than expected. Working with Gregor has been like an injection of rocket fuel in Latchel's engine. He has played a key role in our success.

I have had the privilege to work, mentor and be friends with Gregor for over 15 years. First, at Amazon where he built a great technology team for the Amazon Enterprise Services business and where Gregor was an extremely well respected technology leader, in an organization where there is a high-bar for technology leader. Over the past few years, I have helped mentor Gregor and have a great perspective on his relentless thirst for growth. I would enthusiastically recommend Gregor as an advisor to anyone needing technology leadership, and I would enthusiastically work with Gregor again.

Gregor served as my mentor during my Masters of Science in Technology Management program at Columbia University in NYC. He provided invaluable insight and guidance that helped me refine my Master’s thesis and defense. Gregor is an excellent executive advisor and can absolutely help add genuine value throughout the entire business spectrum of startup entrepreneurs to seasoned Fortune 500 executives. In fact, he was so invaluable that I’ve asked him to serve as on the Board of Advisors for one of our portfolio companies.

Gregor was one of the best managers I have had the pleasure of reporting to. His technical prowess is impressive in both depth and breadth. The most notable thing about Gregor is his strong, internal commitment to "do the right thing," from technical, business, and ethical perspectives; in all three respects his integrity is beyond reproach. His ability to balance a technically superior, aesthetically pleasing solution with the more immediate needs of the business is exceptional; as is his understanding of the business, from the lowest level of the software to the big picture. He is as competent an engineer, as he is as a programmer. As a manager, Gregor took a sincere interest in my career development, and was an excellent mentor. His interpersonal and diplomatic skills are first rate; he is a strategic thinker, entering meetings and negotiations with a clear set of objectives and priorities, able to ferret out solutions that all concerned can live with. He thinks and plans effectively on all time scales concurrently, balancing objectives for the short term with those of the medium and long.. Gregor's relentless drive to further his knowledge is inspiring. To this day, I benefit greatly from exchanging book recommendations with him. His knowledge and interests are incredibly broad, which contributes to his effectiveness as a "people manager," mentor, and general problem solver. I do not hesitate to recommend Gregor, and would not hesitate to stake my own reputation on his performance and reliability. I look forward to our professional paths crossing again.

Gregor was always on the move, and always on top of the details of the strategic goals of the division (Large Account Services) and the implementation and operational details that supported those goals. During meetings with his direct reports, management chain, and clients, he was always poised and focused, showing strategic leadership and technical mastery while building trust. He also made incredible use of time available, such as clearly and succinctly syncing up with people in the moments between meetings. I would be happy to work with Gregor again.

Gregor is your guide to discovering and strengthening your next breakthrough idea. He’s the creative and objective advisor you need who will bring a fresh perspective and powerful -and intuitive - thinking to your organization. For more than two years, Gregor has coached me to think deeper, longer and better about the problems we solve and the clients we serve. Invite him to your inner circle and let him facilitate the creative, entrepreneurial thinking you need to do so that you gain the edge you need.
