A reliable long-term partner for our tech needs

Kavya Bose / Founder | Oct 19, 2026

Overall we had a good experience working with Deviark. We dealt with the same core team throughout, so we did not have to keep re-explaining things. 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. We had to follow up a few times on smaller bug fixes after launch. Overall, a team we trust and plan to keep working with.

Project summary

Deviark was brought in to rebuild our existing mobile app, which had poor reviews and frequent crashes. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 7 months.

Great team to work with — professional, responsive and reliable

Abdullah Al Harbi / Co-Founder | Sep 02, 2026

Deviark 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. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The Blockchain Development work has already made a noticeable difference — tasks that used to take hours now take minutes. I would recommend Deviark to anyone looking for a dependable Blockchain Development partner.

Project summary

Deviark was brought in to build a supply chain traceability prototype on a permissioned blockchain. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 6 months.

Good results, communication improved as the project went on

Neha Agarwal / Head of Digital | Aug 28, 2026

Overall the project was a success, though it was not without some challenges. 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.

We are already seeing better numbers than before the project. Their team changed one developer midway, which slowed things down for a couple of weeks.

We are already discussing the next phase with them.

Project summary

Deviark was brought in to build a demand forecasting model on top of our sales data. The project was split into milestones, with a working build shared at the end of each one. The project took roughly 4 months from kickoff to launch.

Good work overall, with a few bumps along the way

Julie Chen / Founder | Jul 16, 2026

We got a good result in the end, but the road there had a few bumps. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. 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.

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. I would recommend Deviark to anyone looking for a dependable Mobile App Development partner.

Project summary

Deviark was brought in to develop a field-staff app with offline mode that syncs back to our main system. The work covered requirements, design, development, testing and launch support. Overall it was a 5-month engagement.

Exceeded our expectations on quality and communication

Jessica Morgan / IT Director | Jun 22, 2026

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

Oliver Edwards / Founder | Apr 21, 2026

Feedback from our customers has been very positive so far. Estimates on a few features were optimistic and those took longer than planned.

Solid delivery, though timelines needed some pushing

Rachel Carter / Founder | Apr 20, 2026

The final product works well for us, although the process could have been smoother. 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. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

Feedback from our customers has been very positive so far. Documentation at handover was a bit thin and we had to ask for more detail. Overall, a team we trust and plan to keep working with.

Delivered on time and stayed involved after launch

Ravi Rahman / Program Manager | Apr 15, 2026

Our experience with Deviark was really positive from start to finish. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.
