Trente-Douze Delivered a Quality Software Development Solution on Time

Liam MacDonald / Founder | Oct 02, 2026

We were very happy with how this project went. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. 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.

Since launch, everything has been stable and our team has adapted to it quickly. We are already discussing the next phase with them.

Project summary

Our company worked with Trente-Douze to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 8 months from kickoff to launch.

A reliable long-term partner for our tech needs

Meera Bose / Owner | Oct 01, 2026

We were very happy with how this project went. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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. If you need a team that communicates well and delivers, they are a good choice.

Good results, communication improved as the project went on

Bec Murphy / Senior Product Manager | Aug 25, 2026

Overall the project was a success, though it was not without some challenges. 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. They shared working builds regularly, so we could test early and give feedback before things were locked in.

Since launch, everything has been stable and our team has adapted to it quickly. Documentation at handover was a bit thin and we had to ask for more detail. Happy to recommend them.

Capable IoT Development team — happy with the end result

Huda Al Harbi / Co-Founder & CTO | Aug 09, 2026

We got a good result in the end, but the road there had a few bumps. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Since launch, everything has been stable and our team has adapted to it quickly. Their team changed one developer midway, which slowed things down for a couple of weeks. We are already discussing the next phase with them.

Project summary

We engaged Trente-Douze to connect our equipment to a cloud dashboard so we could monitor it remotely. Their team handled planning, development and QA, with our product owner signing off each milestone. Overall it was a 8-month engagement.

Reliable Game Development Partner That Delivered What They Promised

Sophie Barker / IT Director | May 29, 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. 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.

It has made a real difference to how our team works day to day. We are already discussing the next phase with them.

Project summary
