Portrait of István Ráth

About

I am a technology executive and enterprise architecture leader. My work sits where software platforms, product strategy, governance models and digital engineering transformation meet — generally for organizations large and complex enough that those four cannot be separated.

I co-founded IncQuery Labs and led it as CEO for eight years, growing a research-origin technology idea into an enterprise engineering software company of roughly 65 people across Hungary, the United States and Austria, through to its acquisition by PTC. I now lead technical product management and solutions at PTC, and represent the company's 250-person and growing Hungarian organization.

IncQuery Labs grew out of Eclipse VIATRA, the open-source framework for scalable, reactive model queries and transformations, where I am a project lead and committer.

Alongside that I hold an honorary associate professorship at the Budapest University of Technology and Economics, where I remain involved with the Critical Systems Research Group in the Department of Artificial Intelligence and Systems Engineering.
