Quality work, a little slower than we planned

Priya Henderson / Director | Oct 11, 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. 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. Estimates on a few features were optimistic and those took longer than planned. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with Castus Design to move our application to Azure and set up proper backups and monitoring. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 8 months.

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I work as Director at Horizon Market. We operate in Retail & E-commerce and most of our customers are in and around Portland, USA.
What specific problem or business challenge led you to hire this company?
Our team was spending too much time on manual work. The goal was to move our application to Azure and set up proper backups and monitoring so they could focus on customers.
What services did the company provide for your project?
Mainly Cloud Services. They also helped with the technical planning and a few integrations with our existing tools.
Why did you choose this company over other providers you considered?
A colleague recommended them, and our first calls confirmed they understood what we needed.
How clearly did the company understand your requirements and business goals?
They understood our goals quickly, partly because they had worked with Retail & E-commerce clients before.
How was your overall experience with their communication and project management?
Good. Weekly calls, regular updates and a shared board meant we always knew where things stood.
Did the company deliver the project on time and within your expected budget?
Yes. The only extra cost came from features we added ourselves, and they quoted those fairly.
What tangible results or business impact have you seen since the project was completed?
Our team saves several hours a week, and we have had very few issues since launch.
What did you like most about working with this company?
How easy they were to work with. They were responsive, honest and genuinely interested in our success.

Yes, I would recommend them and we plan to work with them again.

Good results, communication improved as the project went on

Oliver Lloyd / Director of Technology | Aug 28, 2026

The final product works well for us, although the process could have been smoother. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.

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. Happy to recommend them.

Project summary

We engaged Castus Design to rebuild an internal order management system that had outgrown its original design. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 5 months.

Capable CRM Development team — happy with the end result

Eric Price / Founder & CEO | Jul 10, 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. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

The result looks great and performs well, and our internal team found it easy to take over. 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 hired Castus Design to customize our CRM and connect it to our website and billing system. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 2 months.

Solid Mobile App Development Work With Clear Communication Throughout

Divya Bose / CEO | Jun 21, 2026

Castus Design did good work for us, and we would use them again. 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. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

We are already seeing better numbers than before the project. A couple of milestones slipped by a week or so, mostly around testing. I would recommend Castus Design to anyone looking for a dependable Mobile App Development partner.

Project summary

We engaged Castus Design 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. We worked together for around 5 months.

Castus Design Delivered a Quality DevOps Services Solution on Time

Lachlan O'Brien / Product Manager | May 27, 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.

The DevOps Services work has already made a noticeable difference — tasks that used to take hours now take minutes. Documentation at handover was a bit thin and we had to ask for more detail.

Happy to recommend them.

Project summary

Castus Design was brought in to set up CI/CD pipelines and automated deployments for our product. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 2 months.
