Delta Source is now officially a part of Brainsquare Group. Together, we offer our clients a comprehensive and complementary range of local, nearshore, and offshore professionals, without changing what has always defined Delta Source: close-knit teams and people who are fully committed to their clients.
A step that felt right
An acquisition is more than just signing a contract. That’s why we took the time to really get to know each other. The process took quite a while, and it quickly became clear that it wasn’t just a good business fit. On a personal level, we were also on the same page.
Brainsquare says it puts the human factor first. That turned out to be more than just a slogan on a website. We noticed it in every conversation. For us, that connection was a prerequisite for taking this step.
Who is Brainsquare?
Brainsquare was founded in 1998 and is headquartered in Zaventem. The company designs, builds, and manages critical application landscapes for organizations with complex IT environments. With more than 250 employees and offices in Belgium, India, and the United States, Brainsquare offers services including application development, integration, managed services with 24/7 support, and Atlassian solutions.
The group also includes Montova, a cloud platform for B2B integration, EDI and e-invoicing, and Lab900, a digital studio spacialized in AI and digital product development. With Delta Source, nearshore software engineering is now being added to that.
What this means for our clients
Every project requires a different approach. Sometimes you need someone based at the client’s office. Sometimes a dedicated team in the same time zone is the best choice, and sometimes you need to be able to scale up quickly and cost-effectively. Within the group, we can now offer all of these models:
- Local: architects, delivery leads and consultants in Belgium, close to the client.
- Nearshore: Delta Source’s development teams in Plovdiv (Bulgaria), with short lines of communication, the same time zone, and a similar work culture.
- Offshore: Brainsquare’s delivery centers in India, offering scalable capacity and round-the-clock support.
This way, we tailor the right mix for each project, rather than using a one-size-fits-all model. And anyone who comes to us has a single point of contact, regardless of where the team is located.
What won’t change
At Delta Source, we’ve never thought in terms of “resources.” Our people aren’t just names on a capacity plan. They form teams that know each other inside and out, rely on one another, and take responsibility together. That’s what makes us strong, and that won’t change.
The same goes for the dedication of our people. They are professionals with a genuine passion for what they do. They make a project their own and aren’t satisfied until the client truly benefits from it. We bring that commitment to the group. Now, it just has even more opportunities.
For our clients, the same points of contact and the same teams will remain on board. Ongoing projects will continue as usual. For our employees, a wider range of new opportunities for growth and learning is opening up.
At Delta Source, we’ve always believed in the power of the pack: close-knit teams where people know each other, count on one another, and work together to achieve the best for the customer. What appealed to us from the very beginning is that Brainsquare views people in the same way. Our pack is growing today, but it remains just as close-knit and at least as driven.
On to a new chapter
We are proud of what we have built with Delta Source, and we look forward to continuing to grow it within the Brainsquare Group. To our customers and partners: thank you for your trust. To our team: this is also thanks to you.
