Steve Bucuvalas
Steve Bucuvalas founded Phase Change in 2005. He is the Inventor, CEO, and a board member.

After selling his prior company eoTek, Steve founded Phase Change in 2005 with the thought: "I've been developing software for decades, there's got to be a better way."

Steve is the Chief Inventor of Phase Change's software digitization. He describes himself as a "cruise missile" aimed at realizing a quantum leap in software productivity, or sometimes, light-heartedly, as the Dr. Emmett Brown of artificial intelligence (AI) in software.

Steve brought an interdisciplinary perspective to solving the software digitization problem and describes finding the solution to software digitization as "constraint solving in theories." He often explains solutions to large issues by combining category theory, computation theory, program analysis, mathematical logic, cognitive science, neuroscience, and human evolution.

Steve is an incessant innovator, serial entrepreneur, and self-taught polymath. He is a man who loves theory and is driven to see its power generate impactful results. Starting with an undergraduate degree in evolutionary biology and a "between degree job" as a bank assembly language programmer, he turned to a life-long career in software innovation.

In his early career, he led corporate advance technology groups initially working on the development of ATM networks, specialized DBMSes, and MVS-exploit identification. Later, during the classical AI period, he ran an AI group focused on developing expert systems for financial services institutions.

In the 90's he transitioned out of large corporations into creating his own innovation-focused organizations, continuing his emphasis on creating practical results using theories from computer science and AI.
