They listened, asked the right questions, and delivered

Maria Foster / CEO | Oct 02, 2026

I would rate this engagement highly on almost every front. We dealt with the same core team throughout, so we did not have to keep re-explaining things. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We launched on schedule and have not had any major issues since.

We are already discussing the next phase with them.

Project summary

We partnered with ExtreemTek to build a demand forecasting model on top of our sales data. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 6 months.

Skilled Mobile App Development Team That Understood Our Business

Overall we had a good experience working with ExtreemTek. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

Feedback from our customers has been very positive so far. We had to follow up a few times on smaller bug fixes after launch. I would recommend ExtreemTek to anyone looking for a dependable Mobile App Development partner.

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

Nicole Foster / Director | Sep 03, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline. 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 AI & Machine Learning work has already made a noticeable difference — tasks that used to take hours now take minutes. We are already discussing the next phase with them.

Project summary

ExtreemTek was brought in to build a demand forecasting model on top of our sales data. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 9 months.
