Good value and a team that genuinely cares about the result

Naledi Naidoo / Senior Product Manager | Oct 02, 2026

Evelyn CS did an excellent job for us. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.

It has made a real difference to how our team works day to day. We would definitely work with them again.

Project summary

We engaged Evelyn CS to run performance and load testing ahead of a big launch. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 5 months.

Amanda Hayes / Founder | Aug 24, 2026

I would rate this engagement highly on almost every front. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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.

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

Quality work, a little slower than we planned

Emma Tremblay / Senior Engineering Manager | May 17, 2026

The final product works well for us, although the process could have been smoother. 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.

The result looks great and performs well, and our internal team found it easy to take over. Estimates on a few features were optimistic and those took longer than planned. If you need a team that communicates well and delivers, they are a good choice.

A reliable long-term partner for our tech needs

Jack Murphy / Marketing Director | Mar 02, 2026

We were happy with the final result. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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.

The Blockchain Development work has already made a noticeable difference — tasks that used to take hours now take minutes. Documentation at handover was a bit thin and we had to ask for more detail.

We are already discussing the next phase with them.

Great Experience With Evelyn CS on Our Blockchain Development Project

Harsh Iyer / IT Director | Jan 27, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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.
