Mainstream joins forces with HC Center in Slovenia 

It’s been in the works since September 2024, and now, we are excited to share: Mainstream has officially joined forces with HC Center, a Slovenian company specialising in cloud, infrastructure, and digital transformation solutions. 

Joining forces with HC Center allows us to reach even more businesses in the region and strengthen our existing presence in Southeast Europe, while keeping our focus firmly on what we do best: delivering high-quality, innovative cloud solutions. 

“This is more than just a partnership; it is a synergy of engineering expertise and cloud vision. Combining our capabilities will provide a full-service offering for our clients, wherever they are in their digital journey. We are excited about taking on new projects together with HC Center and wish to extend a warm welcome to our new team members,” said Ljubiša Radivojević, CEO of Mainstream. 

What makes Mainstream and HC Center better together?

We’d like to take this opportunity to introduce HC Center and explain why this partnership is so important to us. Born in 2001, HC Center is on a mission to deliver innovative IT solutions tailored to the needs of Slovenian businesses. Over the years, they have grown steadily and expanded their services to include cloud computing, data management, and digital transformation. In 2009, HC Center launched its own cloud platform—HC Cloud—in response to the growing need for powerful, flexible, and reliable cloud solutions. 

Besides expanding our team with talented professionals, this partnership strengthens our infrastructure ecosystem, which now includes two data centers with synchronous data replication in Slovenia. With the addition of new data centers, we now operate a network of 11 DC locations across Southeast Europe, making us the largest cloud provider in this part of Europe. 

What this partnership means for our customers 

For our existing and future customers, Mainstream’s collaboration with HC Center brings even more capabilities that accelerate digital transformation and enable IT modernisation with customised solutions. Here’s what Aleksej Kranjec, CEO of HC Center, had to say about this new chapter for our companies: 

“By partnering, we can offer a more extensive range of services. Mainstream’s cloud expertise perfectly aligns with our broader IT infrastructure, digital transformation, cybersecurity, and MSP solutions, creating a complete offering for our clients.” 

 
This view was echoed by Robert Puh, HC Center CTO, who said:

“Mainstream has deep experience with cloud platforms and managed services, which enhances our already strong portfolio. Together, we can offer businesses in Slovenia the full range of cloud options—from private to public clouds—while also providing the necessary infrastructure and security to support their digital transformation.” 

Interested in learning more? 

We see this partnership as the best of both worlds: combining a well-established Slovenian IT company, whose main commitment is to building strong client relationships, with a multi-cloud provider equally dedicated to offering high-quality services that support businesses on their growth journey. 

 
If you’re reading this, you’re familiar with who we are. We want you to know that this will never change—we are still the same provider that over 300 businesses across the region rely on. This new chapter is not about reinventing ourselves but about reinventing the future of cloud and digital transformation together with HC Center.
