Quality work, a little slower than we planned

Jason Sullivan / Head of Digital Transformation | Sep 12, 2026

The final product works well for us, although the process could have been smoother. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We are already seeing better numbers than before the project. Documentation at handover was a bit thin and we had to ask for more detail.

Overall, a team we trust and plan to keep working with.

Project summary

Black Core SP.Zo.o.S.k was brought in to provide ongoing monitoring and support for our cloud infrastructure. They worked alongside our in-house team, which mostly handled business requirements and testing. Overall it was a 4-month engagement.

Solid Data & Analytics Work With Clear Communication Throughout

Sophie Doyle / Managing Director | May 15, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The result looks great and performs well, and our internal team found it easy to take over. We would definitely work with them again.

Project summary

Black Core SP.Zo.o.S.k was brought in to build dashboards that pull our sales, marketing and finance data into one place. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 9 months.

Professional AI & Machine Learning Team, Smooth Delivery From Start to Finish

Jessica Johnson / Chief Digital Officer | May 04, 2026

Our experience with Black Core SP.Zo.o.S.k was really positive from start to finish. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

It has made a real difference to how our team works day to day.

If you need a team that communicates well and delivers, they are a good choice.
