John Van Siclen

Chief Executive Officer

John is a native Californian and long-time Silicon Valley exec. As a Valley entrepreneur, he made a career of building successful tech companies in highly competitive markets. In fact, CRN Magazine named John a “Top 25 Disrupter” for his relentless focus on breaking the mold and championing new business models. When he moved to the right coast in 2008, John met Bernd Greifeneder, Founder and CTO of the original dynaTrace, and the rest is history – from $4m to $400m in 7 years. A lifelong hockey player, captaining his Princeton hockey team taught John how to build strong, competitive, winning teams. At Dynatrace, he’s surrounded himself with people just as motivated, driven and passionate about innovation and customer success. The result is a market-leading company with revenues far outpacing our nearest competitor. The father of 4 boys, John is a founding member of the New England Clean Energy executive program, and US Pond Hockey Seniors Champion.
