Professional Web Development Team, Smooth Delivery From Start to Finish

Heather Hayes / CEO | Oct 09, 2026

Aionys did an excellent job for us. 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. They shared working builds regularly, so we could test early and give feedback before things were locked in.

Since launch, everything has been stable and our team has adapted to it quickly. Overall, a team we trust and plan to keep working with.

Project summary

Aionys was brought in to build a customer portal where clients can log in, track orders and download invoices. Their team handled planning, development and QA, with our product owner signing off each milestone. Overall it was a 8-month engagement.

Great Experience With Aionys on Our Mobile App Development Project

Nathan Nguyen / Director | Sep 24, 2026

Aionys did good work for us, and we would use them again. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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. We had to follow up a few times on smaller bug fixes after launch.

We are already discussing the next phase with them.

Project summary

We partnered with Aionys to build iOS and Android apps for our customers, including booking, payments and push notifications. The work covered requirements, design, development, testing and launch support. The project took roughly 4 months from kickoff to launch.

Great Experience With Aionys on Our Blockchain Development Project

Lauren Henderson / Co-Founder | Sep 13, 2026

We were happy with the final result. 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. 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.

The result looks great and performs well, and our internal team found it easy to take over. A couple of milestones slipped by a week or so, mostly around testing. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We engaged Aionys to build a supply chain traceability prototype on a permissioned blockchain. Their team handled planning, development and QA, with our product owner signing off each milestone. Overall it was a 3-month engagement.

Reliable E-commerce Development Partner That Delivered What They Promised

Chloe Wilson / Co-Founder | Jan 23, 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. 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.

We launched on schedule and have not had any major issues since. We would definitely work with them again.

Quality work, a little slower than we planned

Oliver Edwards / Managing Director | Jan 12, 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. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. Their team changed one developer midway, which slowed things down for a couple of weeks.

Happy to recommend them.

Project summary

Our company worked with Aionys to rebuild our existing mobile app, which had poor reviews and frequent crashes. The work covered requirements, design, development, testing and launch support. The project took roughly 2 months from kickoff to launch.
