Professional team that made a complex project feel manageable

Rachel Goh / Founder | Oct 07, 2026

The project went well overall. They shared working builds regularly, so we could test early and give feedback before things were locked in. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The Software 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.

Overall, a team we trust and plan to keep working with.

Project summary

Our company worked with PreludeSys to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. They worked alongside our in-house team, which mostly handled business requirements and testing. The engagement ran for about 6 months.

Questions & Answers

Please describe your company, your role, and the industry you operate in.

I'm the Founder at Atlas Green Solutions Pte Ltd, a Environmental Services company based in Singapore. I look after our technology and work closely with outside partners on bigger projects.

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 build a custom operations platform to replace the spreadsheets and email threads we were running the business on so they could focus on customers.

What services did the company provide for your project?

Software Development, plus QA and some consulting on how to structure the project.

Why did you choose this company over other providers you considered?

Their pricing was fair and they were honest about timelines instead of just telling us what we wanted to hear.

How clearly did the company understand your requirements and business goals?

Very well. They asked a lot of questions upfront and turned our rough ideas into a clear plan.

How was your overall experience with their communication and project management?

Communication was good overall and improved further once we settled into a routine.

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.

It is still early, but the numbers are trending in the right direction and the system has been stable.

Professional UI/UX Design Team, Smooth Delivery From Start to Finish

James Barker / Director of IT | Oct 02, 2026

I would rate this engagement highly on almost every front. 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.

The result looks great and performs well, and our internal team found it easy to take over. If you need a team that communicates well and delivers, they are a good choice.

Project summary

Our company worked with PreludeSys to redesign the user experience of our SaaS product. Their team handled planning, development and QA, with our product owner signing off each milestone. The engagement ran for about 7 months.

I work as Director of IT at Lakeshore Digital Ltd. We operate in Information Technology and most of our customers are in and around Edinburgh, UK.

What specific problem or business challenge led you to hire this company?

We had tried to do this internally and it stalled. We needed specialists to redesign the user experience of our SaaS product.

What services did the company provide for your project?

End-to-end UI/UX Design — from requirements and design through to deployment and a support period afterwards.

Why did you choose this company over other providers you considered?

We compared three or four agencies. PreludeSys asked the best questions and had good reviews from past clients.

How clearly did the company understand your requirements and business goals?

Well. There were a couple of points we had to clarify early on, but after that they were spot on.

How was your overall experience with their communication and project management?

Very responsive. We usually heard back the same day, even with the time difference.

Did the company deliver the project on time and within your expected budget?

Mostly. One milestone slipped by about a week, but the final delivery was on schedule and the budget held.

What tangible results or business impact have you seen since the project was completed?

We can now handle more volume without adding staff, which was the main goal.

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.

Would you recommend this company to others, and would you work with them again?

Yes. They are a reliable UI/UX Design partner.

Would happily work with them again

Thabo Naidoo / Director of IT | Sep 28, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

The result looks great and performs well, and our internal team found it easy to take over.

I would recommend PreludeSys to anyone looking for a dependable IoT Development partner.

Project summary

Our company worked with PreludeSys to connect our equipment to a cloud dashboard so we could monitor it remotely. They worked alongside our in-house team, which mostly handled business requirements and testing. Overall it was a 2-month engagement.
