Reliable AI & Machine Learning Partner That Delivered What They Promised

Neha Verma / IT Director | Oct 18, 2026

The project went well overall. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They were upfront about what was realistic within our budget, which helped us prioritise the right features. When we changed our minds on a couple of features halfway through, they handled it without fuss and were clear about the impact on cost and timeline.

The result looks great and performs well, and our internal team found it easy to take over. There were some early misunderstandings on requirements that took a few rounds to sort out.

Happy to recommend them.

Project summary

Greymatters d.o.o. was brought in to add an AI chatbot to our support site that answers questions from our help docs. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 3-month engagement.

Solid AI & Machine Learning Work With Clear Communication Throughout

Tobias Becker / Chief Digital Officer | Sep 26, 2026

Greymatters d.o.o. did an excellent job for us. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

The AI & Machine Learning work has already made a noticeable difference — tasks that used to take hours now take minutes.

I would recommend Greymatters d.o.o. to anyone looking for a dependable AI & Machine Learning partner.

Project summary

Greymatters d.o.o. was brought in to automate document data extraction that our team was doing by hand. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 7 months.
