People behind

It all started back in 2012 with the acquaintance of two guys, Rajko Machold and Alexey Romankov. The timing was perfect, as Rajko was looking to digitalize the services his newly founded company APEGG offered to glass container manufacturers. By that time, Alexey decided to leave the oil and gas sector, and was looking to create industrial solutions using digital technologies. The collaboration and their creativity gave rise to well-known digital products for glass container manufacturers such as GCFDA, DES and GOB Forming Simulator. Whilst working on the different applications the team became bigger and an opportunity arose to create a digital platform for the glass industry, which Rajko and Alexey discussed and dreamed about all this time.


In 2016, the Glass Open Book digital platform was officially launched by HOLDRA Limited, which was founded by Rajko and Alexey specifically for the development and maintenance of the platform.


Under the Glass Open Book (GOB) brand, HOLDRA provides various digital and media services for the glass industry, promoting the excellence of glass as an environmentally friendly material, and creates socially significant and commercial multimedia content.
