Zest Fission Reviews

Capable Software Development team — happy with the end result

Eric Miller / VP of Engineering | Oct 19, 2026

We got a good result in the end, but the road there had a few bumps. 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. 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.

Feedback from our customers has been very positive so far. We had to follow up a few times on smaller bug fixes after launch. Happy to recommend them.

Project summary

We engaged Zest Fission to develop a scheduling and dispatch tool for our field team. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 5-month engagement.

Professional team that made a complex project feel manageable

Marcus Lim / Director | Sep 20, 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. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Feedback from our customers has been very positive so far. We would definitely work with them again.

Project summary

Our company worked with Zest Fission to build a customer portal where clients can log in, track orders and download invoices. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 6-month engagement.

Great Experience With Zest Fission on Our AI & Machine Learning Project

Noah Gagnon / Director | Sep 19, 2026

Overall we had a good experience working with Zest Fission. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

Feedback from our customers has been very positive so far. A couple of milestones slipped by a week or so, mostly around testing. I would recommend Zest Fission to anyone looking for a dependable AI & Machine Learning partner.

Good results, communication improved as the project went on

Callum Evans / IT Director | Aug 24, 2026

The final product works well for us, although the process could have been smoother. 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. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

A reliable long-term partner for our tech needs

We were happy with the final result. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

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. Estimates on a few features were optimistic and those took longer than planned. We are already discussing the next phase with them.
