Industrial High-Technology Group


Previan is an industrial high-technology group that is redefining the standard of infrastructure monitoring and diagnostics.

Previan drives strategic orientations, capital allocation decisions and investor relations. At the core of each of our investments is the determination to drive innovation and deliver the world’s most advanced technology solutions to the marketplace.

Business Units

To maintain an entrepreneurial mindset and a relentless customer focus, the group is composed of several business units operating as autonomous platforms. While self-directed, these business units all share a common purpose: to push the limits of advanced technology to keep the world’s infrastructure safe and productive. Previan’s business units are grouped into two segments: Diagnostics and Remote Technologies (DRMT) and Technology as a Service (TaaS).
