A reliable long-term partner for our tech needs

Ravi Khan / Co-Founder | Oct 15, 2026

We were very happy with how this project went. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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 Web Development work has already made a noticeable difference — tasks that used to take hours now take minutes.

If you need a team that communicates well and delivers, they are a good choice.

Project summary

We hired Korevariance 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. The project took roughly 3 months from kickoff to launch.

I work as Co-Founder at Pioneer Creative. We operate in Advertising & Marketing and most of our customers are in and around Abu Dhabi, UAE.

Great Experience With Korevariance on Our Mobile App Development Project

Nathan Murphy / Co-Founder & CTO | Sep 21, 2026

I would rate this engagement highly on almost every front. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Feedback from our customers has been very positive so far.

We would definitely work with them again.

Project summary

Our company worked with Korevariance to develop a field-staff app with offline mode that syncs back to our main system. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 8-month engagement.

How clearly did the company understand your requirements and business goals?
They understood our goals quickly, partly because they had worked with Pharmaceuticals & Biotechnology clients before.
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?
It was delivered on time, and the final invoice matched the original estimate.

Definitely. We have already started talking about the next phase.

They listened, asked the right questions, and delivered

Kevin Carter / Project Manager | Sep 09, 2026

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

It has made a real difference to how our team works day to day. Happy to recommend them.

Delivered on time and stayed involved after launch

Chris Hayes / Chief Digital Officer | May 17, 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 team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. 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.

It has made a real difference to how our team works day to day. There were some early misunderstandings on requirements that took a few rounds to sort out. We would definitely work with them again.

Project summary

Overall we had a good experience working with Korevariance. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

Good work overall, with a few bumps along the way

Tobias Fischer / Engineering Manager | Feb 03, 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 shared working builds regularly, so we could test early and give feedback before things were locked in.

Feedback from our customers has been very positive so far. Their team changed one developer midway, which slowed things down for a couple of weeks. If you need a team that communicates well and delivers, they are a good choice.
