Our clients

The success of our clients is a success for Delta! See all

Our website was down often, mainly because of reaching the limit of our resources. In such moments we lose done deals just in the months busiest in marketing activities. After we moved to Delta Cloud the site is loading several times faster on a normal day and the cloud is giving us the possibility to scale easily our resources, whenever we need it.

Tatyana Atanasova

Website Manager, Sanita.bg

While being in our previous provider, our website was down too often. Delta team took the issue professionally, analyzing the load and the software used, so to make up a plan how to remove and avoid the causes of failure, as well as speed up the loading of the site. 

The Support guys helped us on our questions and issues right on time. 

Konrad Raisemund

Owner, IVET.bg

After we moved our online store in Delta.bg, it started to load pretty quickly. On the first Black Friday since we moved, we made three times as much sales as the previous year. In case of any issue, the support was quick and adequate even in 3 AM.
