Great team to work with — professional, responsive and reliable

Isla O'Brien / Program Manager | Oct 07, 2026

Our experience with BlockchainX was really positive from start to finish. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They were upfront about what was realistic within our budget, which helped us prioritise the right features. 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.

We would definitely work with them again.

Professional CRM Development Team, Smooth Delivery From Start to Finish

Julia Weber / VP of Engineering | Aug 30, 2026

Overall we had a good experience working with BlockchainX. Their project manager kept things organised and was quick to flag anything that might affect the timeline. 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 were happy with the final result. 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.

They listened, asked the right questions, and delivered

Lucy Wright / Director | Mar 21, 2026
