Professional Blockchain Development Team, Smooth Delivery From Start to Finish

Vikram Gupta / CEO | Aug 23, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Since launch, everything has been stable and our team has adapted to it quickly. We would definitely work with them again.

Project summary

We hired DSI 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. The project took roughly 7 months from kickoff to launch.

Quality work, a little slower than we planned

Ben Walker / Co-Founder & CTO | May 15, 2026

Overall the project was a success, though it was not without some challenges. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

We launched on schedule and have not had any major issues since. 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 partnered with DSI 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. The project took roughly 4 months from kickoff to launch.

Exceeded our expectations on quality and communication

Chloe Thompson / Senior Product Manager | Apr 30, 2026

DSI 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. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

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

We would definitely work with them again.

Reliable Mobile App Development Partner That Delivered What They Promised

Sam Walker / Director of Technology | Apr 14, 2026

The project went well overall. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We are already seeing better numbers than before the project. 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.
