Great Experience With TESI on Our Software Development Project

Brandon Brooks / Head of Product | Oct 08, 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

The result looks great and performs well, and our internal team found it easy to take over. I would recommend TESI to anyone looking for a dependable Software Development partner.

Project summary

We hired TESI to develop a scheduling and dispatch tool for our field team. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 2-month engagement.

Organised and transparent. Their project manager kept the project on track and flagged risks early.

Capable AI & Machine Learning team — happy with the end result

Sara Saleh / Director | Jul 17, 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 were upfront about what was realistic within our budget, which helped us prioritise the right features. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We launched on schedule and have not had any major issues since. Estimates on a few features were optimistic and those took longer than planned. Overall, a team we trust and plan to keep working with.

Project summary

TESI was brought in to build a demand forecasting model on top of our sales data. They also took care of integrations with a couple of third-party tools we already used. The project took roughly 5 months from kickoff to launch.

Good results, communication improved as the project went on

Thijs Smit / Managing Director | Apr 26, 2026

Overall the project was a success, though it was not without some challenges. They shared working builds regularly, so we could test early and give feedback before things were locked in. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

Feedback from our customers has been very positive so far. Their team changed one developer midway, which slowed things down for a couple of weeks. We would definitely work with them again.

Great team to work with — professional, responsive and reliable

I would rate this engagement highly on almost every front. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Their project manager kept things organised and was quick to flag anything that might affect the timeline.
