CAD Exchanger CEO Roman Lygin

If data is the new oil then 3D data is the key asset of any company.

Our technologies help software developers and end-users to work, share and collaborate on 3D data, which can come in any format, from any source, on any platform.

CADEX was founded in 2014 by Roman Lygin, a veteran with 20+ years of experience in CAD data exchange, parallel computations and project management in EADS Matra Datavision, Open CASCADE and Intel. However, the roots go five years back when CAD Exchanger started as Roman’s hobby project and gained great traction by users who were still facing CAD data conversion challenges.

Today CAD Exchanger solutions empower hundreds of thousands of end-user seats through software vendors.

With the help of our solutions, large businesses improve their returns on investments and can focus on their core R&D. Start-ups and medium businesses now have access to CAD technologies they previously could not even afford. We challenge the status quo established 20 years ago and help businesses around the world to work with 3D data.
