Radical I/O Reviews

Easy to work with and very transparent on timelines and cost

Emma Campbell / Head of Engineering | Sep 07, 2026

Overall we had a good experience working with Radical I/O. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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. Their team changed one developer midway, which slowed things down for a couple of weeks. Overall, a team we trust and plan to keep working with.

Project summary

We hired Radical I/O to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. The work covered requirements, design, development, testing and launch support. The project took roughly 4 months from kickoff to launch.

Professional Software Development Team, Smooth Delivery From Start to Finish

Dan Sullivan / Director | Sep 05, 2026

Radical I/O did an excellent job for us. They shared working builds regularly, so we could test early and give feedback before things were locked in. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We are already seeing better numbers than before the project.

Happy to recommend them.

The project went well overall. 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.

Reliable IoT Development Partner That Delivered What They Promised

Lauren Bennett / Co-Founder & CTO | Aug 13, 2026

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

Solid delivery, though timelines needed some pushing

Brandon Wallace / Senior Engineering Manager | Apr 26, 2026

We got a good result in the end, but the road there had a few bumps. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

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. I would recommend Radical I/O to anyone looking for a dependable Web Development partner.

Project summary

Our company worked with Radical I/O to rebuild a slow, outdated web app and move it to a new framework. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 6-month engagement.
