Brainsquare Group strengthens delivery capabilities with Delta Source

Zaventem, Belgium — November 9, 2026 — Brainsquare, the Belgian-headquartered IT service provider with global reach, announces the acquisition of Delta Source. The addition strengthens Brainsquare's expertise in software engineering while expanding the group's international delivery capabilities with a nearshore development team in Plovdiv, Bulgaria.

Founded in Belgium, Delta Source has built a strong technical team in Bulgaria and delivers software engineering services to customers through its office in Plovdiv. The city is one of Bulgaria's leading university hubs and provides access to a strong pool of technical talent, supporting future growth of the team.

The acquisition complements Brainsquare's existing international organization. Together with the group's established development teams in India, the Bulgarian office adds a European nearshore delivery capability for customers who prefer or require project execution within Europe.

"Delta Source brings valuable technical expertise and a well-established team in Bulgaria," said Mark Van Hamme, CEO of Brainsquare. "For some of our customers, having both nearshore and offshore delivery options offers valuable flexibility. The addition of Delta Source allows us to better support those needs while further strengthening the international capabilities of the Brainsquare Group."

Delta Source will become part of the Brainsquare Group, combining its technical expertise with Brainsquare's long-standing customer relationships, managed services capabilities and international delivery organization. For Delta Source, joining Brainsquare provides access to a broader organization with established commercial, operational and support services, allowing the team to focus on delivering technical excellence while becoming part of a larger international IT services group.
