Good results, communication improved as the project went on

Chris Sullivan / VP of Engineering | Sep 24, 2026

The final product works well for us, although the process could have been smoother. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

Feedback from our customers has been very positive so far. Estimates on a few features were optimistic and those took longer than planned. Happy to recommend them.

Project summary

We hired Sentinel Technologies Ltd to run performance and load testing ahead of a big launch. The work covered requirements, design, development, testing and launch support. We worked together for around 9 months.

Solid CRM Development Work With Clear Communication Throughout

Johan van der Merwe / Product Manager | Aug 27, 2026

Our experience with Sentinel Technologies Ltd was really positive from start to finish. 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

We launched on schedule and have not had any major issues since. We are already discussing the next phase with them.

Project summary

We hired Sentinel Technologies Ltd to build custom CRM modules for how our sales process actually works. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 2 months.

Easy to work with and very transparent on timelines and cost

Good work overall, with a few bumps along the way

Wei Jie Goh / CEO | Jul 26, 2026

The final product works well for us, although the process could have been smoother. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

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.
