How to get in touch with anyone from UrBackup for commercial reasons?

I am not able to find any way to contact UrBackup directly. Apart from the Windows Block changes is there no other way to purchase a license or support package?

I would like to implement UrBackup in one our projects but due to the high security and reliability requirements of our client we need to have a support license for all of the software we deploy. I would like to know if this is possible.
There are other solution like Veam or acronis which I dislike because of their proprietary formats. Having used UrBackup at my home lab and office I would like to continue to use them in our projects as it is much more easily manageable than other options.
