Easy to work with and very transparent on timelines and cost

Brandon Bennett / Founder & CEO | Oct 10, 2026

Overall we had a good experience working with Sanjay Dey. 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.

The Mobile App 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. We would definitely work with them again.

Project summary

We hired Sanjay Dey to build iOS and Android apps for our customers, including booking, payments and push notifications. They worked alongside our in-house team, which mostly handled business requirements and testing. The engagement ran for about 7 months.

Good work overall, with a few bumps along the way

Daan Jansen / CEO | Aug 23, 2026

Overall the project was a success, though it was not without some challenges. 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

It has made a real difference to how our team works day to day. Documentation at handover was a bit thin and we had to ask for more detail. I would recommend Sanjay Dey to anyone looking for a dependable AR/VR Development partner.

Project summary

We engaged Sanjay Dey to build an AR product viewer so customers can preview items in their own space. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 9 months.

Priya Fisher / Chief Digital Officer | Jun 26, 2026
