Quality work, a little slower than we planned

Ryan Wallace / Founder & CEO | Sep 17, 2026

The final product works well for us, although the process could have been smoother. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They shared working builds regularly, so we could test early and give feedback before things were locked in.

We are already seeing better numbers than before the project. A couple of milestones slipped by a week or so, mostly around testing.

Happy to recommend them.

Project summary

We hired Fission Monster to automate document data extraction that our team was doing by hand. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 5 months.

Solid Web Development Work With Clear Communication Throughout

Jessica Henderson / Co-Founder | Jul 31, 2026

Fission Monster did good work for us, and we would use them again. They were upfront about what was realistic within our budget, which helped us prioritise the right features. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The Web Development work has already made a noticeable difference — tasks that used to take hours now take minutes. There were some early misunderstandings on requirements that took a few rounds to sort out. We would definitely work with them again.

Project summary

We engaged Fission Monster to build a customer portal where clients can log in, track orders and download invoices. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 9 months from kickoff to launch.

Great Experience With Fission Monster on Our IoT Development Project

Ananya Mehta / Owner | May 23, 2026

We were very happy with how this project went. They were upfront about what was realistic within our budget, which helped us prioritise the right features. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

We are already seeing better numbers than before the project.

Happy to recommend them.

Project summary

We partnered with Fission Monster to set up a sensor network and alerts for our cold storage facilities. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 6 months.

Good work overall, with a few bumps along the way

Pieter Dlamini / Co-Founder & CTO | May 21, 2026

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

The result looks great and performs well, and our internal team found it easy to take over. Documentation at handover was a bit thin and we had to ask for more detail. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We engaged Fission Monster to set up a sensor network and alerts for our cold storage facilities. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 8 months.

They listened, asked the right questions, and delivered

Ravi Al Mansoori / Operations Manager | May 17, 2026

Overall we had a good experience working with Fission Monster. We dealt with the same core team throughout, so we did not have to keep re-explaining things. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. 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.

Exceeded our expectations on quality and communication

Ethan Campbell / Head of Product | Apr 12, 2026

I would rate this engagement highly on almost every front. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

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

Fission Monster was brought in to develop a field-staff app with offline mode that syncs back to our main system. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 5 months.
