Quality work, a little slower than we planned

Lotte Bakker / IT Manager | Oct 06, 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.

It has made a real difference to how our team works day to day. A couple of milestones slipped by a week or so, mostly around testing.

We are already discussing the next phase with them.

Project summary

We engaged ZENTENSE to run performance and load testing ahead of a big launch. The work covered requirements, design, development, testing and launch support. The project took roughly 2 months from kickoff to launch.

Easy to work with and very transparent on timelines and cost

Emma Thompson / Senior Engineering Manager | Oct 02, 2026

ZENTENSE did good work for us, and we would use them again. 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.

We launched on schedule and have not had any major issues since. There were some early misunderstandings on requirements that took a few rounds to sort out. I would recommend ZENTENSE to anyone looking for a dependable Blockchain Development partner.

Project summary

ZENTENSE was brought in to build a supply chain traceability prototype on a permissioned blockchain. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 5 months.

Skilled Mobile App Development Team That Understood Our Business

Saud Al Zahrani / Owner | Jun 07, 2026

Our experience with ZENTENSE was really positive from start to finish. They shared working builds regularly, so we could test early and give feedback before things were locked in. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

Since launch, everything has been stable and our team has adapted to it quickly. I would recommend ZENTENSE to anyone looking for a dependable Mobile App Development partner.

Dependable Web Development Partner for a Growing Advertising & Marketing Business

Andre Hughes / Engineering Manager | Mar 23, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. 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.

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

Project summary

We hired ZENTENSE 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 3 months from kickoff to launch.
