Delivered on time and stayed involved after launch

Charlotte Harding / Operations Manager | Oct 18, 2026

We were very happy with how this project went. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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.

We launched on schedule and have not had any major issues since. Overall, a team we trust and plan to keep working with.

Project summary

We engaged CoreTeam.io to build a demand forecasting model on top of our sales data. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 9-month engagement.

Strong Technical Skills and a Very Responsive Web Development Team

James Walker / Director | Sep 30, 2026

CoreTeam.io did an excellent job for us. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Since launch, everything has been stable and our team has adapted to it quickly. We would definitely work with them again.

Project summary

CoreTeam.io was brought in to rebuild a slow, outdated web app and move it to a new framework. Their team handled planning, development and QA, with our product owner signing off each milestone. The project took roughly 7 months from kickoff to launch.

Good results, communication improved as the project went on

Bec Harris / Owner | May 31, 2026

The final product works well for us, although the process could have been smoother. Communication was consistent.

They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Professional Mobile App Development Team, Smooth Delivery From Start to Finish

Lucy Ahmed / Head of Product | May 19, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They were upfront about what was realistic within our budget, which helped us prioritise the right features. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes.

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