Quality work, a little slower than we planned

Kavya Shah / Co-Founder | Oct 03, 2026

We got a good result in the end, but the road there had a few bumps. 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. 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. We had to follow up a few times on smaller bug fixes after launch.

Happy to recommend them.

Project summary

Great Experience With DayOne s.c. on Our UI/UX Design Project

Kavya Agarwal / Co-Founder & CTO | Sep 30, 2026

Overall we had a good experience working with DayOne s.c.. 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.

The UI/UX Design work has already made a noticeable difference — tasks that used to take hours now take minutes. Documentation at handover was a bit thin and we had to ask for more detail.

We are already discussing the next phase with them.

Project summary

We engaged DayOne s.c. to build a design system so our product looked consistent across screens. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 3 months.

Good results, communication improved as the project went on

Noura Fernandes / Chief Digital Officer | Sep 07, 2026

We got a good result in the end, but the road there had a few bumps. 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 are already seeing better numbers than before the project. Their team changed one developer midway, which slowed things down for a couple of weeks. Overall, a team we trust and plan to keep working with.

Project summary

We engaged DayOne s.c. to automate document data extraction that our team was doing by hand. They worked alongside our in-house team, which mostly handled business requirements and testing. The project took roughly 6 months from kickoff to launch.

Dependable Web Development Partner for a Growing Automotive Business

Neha Reddy / Senior Product Manager | Jul 24, 2026

DayOne s.c. did an excellent job for us. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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. We are already discussing the next phase with them.

Skilled Web Development Team That Understood Our Business

Nathan Smith / Managing Director | Apr 30, 2026

DayOne s.c. did good work for us, and we would use them again. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Feedback from our customers has been very positive so far. There were some early misunderstandings on requirements that took a few rounds to sort out. We are already discussing the next phase with them.
