Carbon Five Reviews

Professional team that made a complex project feel manageable

Jack Murphy / Founder & CEO | Oct 17, 2026

I would rate this engagement highly on almost every front. 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. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

It has made a real difference to how our team works day to day. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We hired Carbon Five to add an AI chatbot to our support site that answers questions from our help docs. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 3 months.

Carbon Five Delivered a Quality Mobile App Development Solution on Time

Sam Edwards / Founder | May 22, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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. 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. I would recommend Carbon Five to anyone looking for a dependable Mobile App Development partner.

Project summary

Good work overall, with a few bumps along the way

Kelly Johnson / Director of Technology | Apr 28, 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. 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. There were some early misunderstandings on requirements that took a few rounds to sort out.

I would recommend Carbon Five to anyone looking for a dependable AI & Machine Learning partner.

Project summary

We partnered with Carbon Five to build a demand forecasting model on top of our sales data. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 9 months.

Great team to work with — professional, responsive and reliable

Kevin Coleman / Senior Engineering Manager | Apr 28, 2026

We were happy with the final result. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

It has made a real difference to how our team works day to day. A couple of milestones slipped by a week or so, mostly around testing. I would recommend Carbon Five to anyone looking for a dependable AI & Machine Learning partner.

Great Experience With Carbon Five on Our Software Development Project

Andre Hayes / Director of Technology | Apr 11, 2026

The project went well overall. 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. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

Since launch, everything has been stable and our team has adapted to it quickly. Estimates on a few features were optimistic and those took longer than planned.

I would recommend Carbon Five to anyone looking for a dependable Software Development partner.

Solid Mobile App Development Work With Clear Communication Throughout
