Mainstream is a cloud infrastructure and managed hosting provider serving businesses across Southeast Europe. With a team of more than 100 cloud and system engineers, the company delivers end-to-end cloud services spanning every stage of a client's journey: readiness assessment, strategy development, migration, management, and ongoing optimization. Its client base spans enterprise banking, retail, and technology startups.
The company's service model is built around full-cycle cloud engagements. Rather than offering point solutions, Mainstream works with clients from initial evaluation through to active cloud management and performance optimization - a scope that demands engineers comfortable operating across multiple disciplines and project stages.
Internally, Mainstream describes its culture as flat and collaborative, with an emphasis on transparency and open communication. Engineers are expected to take initiative, and the company states that suggestions for process improvements or new approaches are actively considered and implemented. Knowledge-sharing across teams is treated as a standard practice rather than an exception.
