COLTFOX PRIVATE LIMITED Reviews

Capable UI/UX Design team — happy with the end result

Sanne Jansen / Senior Product Manager | Oct 01, 2026

We got a good result in the end, but the road there had a few bumps. 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. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

Since launch, everything has been stable and our team has adapted to it quickly. A couple of milestones slipped by a week or so, mostly around testing.

Happy to recommend them.

Project summary

A reliable long-term partner for our tech needs

Ben Harding / Co-Founder | Sep 12, 2026

COLTFOX PRIVATE LIMITED did an excellent job for us. They were upfront about what was realistic within our budget, which helped us prioritise the right features. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They shared working builds regularly, so we could test early and give feedback before things were locked in.

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

We would definitely work with them again.

Quality work, a little slower than we planned

Jess Wright / Founder & CEO | Apr 23, 2026

We got a good result in the end, but the road there had a few bumps. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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.

We are already seeing better numbers than before the project. We had to follow up a few times on smaller bug fixes after launch. Overall, a team we trust and plan to keep working with.

Project summary

Our company worked with COLTFOX PRIVATE LIMITED 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. The project took roughly 9 months from kickoff to launch.
