Good value and a team that genuinely cares about the result

Hui Min Chua / CEO | Sep 05, 2026

Cortana did an excellent job for us. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

We launched on schedule and have not had any major issues since. Overall, a team we trust and plan to keep working with.

Project summary

Cortana was brought in to build a Web3 dashboard and wallet integration for our platform. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 3-month engagement.

Great team to work with — professional, responsive and reliable

Sophie Barker / Managing Director | Aug 29, 2026

Cortana did good work for us, and we would use them again. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. 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.

We launched on schedule and have not had any major issues since. Estimates on a few features were optimistic and those took longer than planned.

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

Project summary

Cortana was brought in to build a customer portal where clients can log in, track orders and download invoices. The work covered requirements, design, development, testing and launch support. The project took roughly 6 months from kickoff to launch.

Solid Blockchain Development Work With Clear Communication Throughout

Ruben Jansen / Engineering Manager | Aug 04, 2026

The project went well overall. 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. Estimates on a few features were optimistic and those took longer than planned. I would recommend Cortana to anyone looking for a dependable Blockchain Development partner.

They listened, asked the right questions, and delivered

Conor Walsh / VP of Engineering | May 23, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

We are already seeing better numbers than before the project. We are already discussing the next phase with them.

Easy to work with and very transparent on timelines and cost

Andre Sullivan / Co-Founder | Apr 16, 2026

The project went well overall. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

Feedback from our customers has been very positive so far. A couple of milestones slipped by a week or so, mostly around testing.

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

Strong Technical Skills and a Very Responsive E-commerce Development Team

Eric Price / Operations Manager | Apr 12, 2026
