Good value and a team that genuinely cares about the result

Nicole Hayes / CEO | Jul 20, 2026

L'Effet Monstre did an excellent job for us. Their project manager kept things organised and was quick to flag anything that might affect the timeline. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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. We are already discussing the next phase with them.

Project summary

We hired L'Effet Monstre to develop a scheduling and dispatch tool for our field team. The work covered requirements, design, development, testing and launch support. The project took roughly 5 months from kickoff to launch.

They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Easy to work with and very transparent on timelines and cost

Naledi Botha / Engineering Manager | Jun 24, 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. They shared working builds regularly, so we could test early and give feedback before things were locked in. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The result looks great and performs well, and our internal team found it easy to take over. We are already discussing the next phase with them.

Project summary

Our company worked with L'Effet Monstre to develop a scheduling and dispatch tool for our field team. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 4 months.

Honest advice and solid execution

Carlos Price / Managing Director | May 14, 2026

L'Effet Monstre did an excellent job for us. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.

The Software Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We would definitely work with them again.

Project summary

L'Effet Monstre was brought in 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. Overall it was a 5-month engagement.

We were happy with the final result. 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.
