Good work overall, with a few bumps along the way

Priya Coleman / Founder | Sep 21, 2026

The final product works well for us, although the process could have been smoother. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They shared working builds regularly, so we could test early and give feedback before things were locked in.

We are already seeing better numbers than before the project. We had to follow up a few times on smaller bug fixes after launch.

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

Project summary

We hired Danubio to redesign and rebuild our company website on a modern stack. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 4 months.

Exceeded our expectations on quality and communication

Tyler Foster / Operations Manager | Jul 28, 2026

I would rate this engagement highly on almost every front. 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.

Feedback from our customers has been very positive so far.

I would recommend Danubio to anyone looking for a dependable Mobile App Development partner.

We hired Danubio to build iOS and Android apps for our customers, including booking, payments and push notifications. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 7 months from kickoff to launch.

Honest advice and solid execution

James Clarke / IT Director | May 29, 2026

We were happy with the final result. 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.

We are already seeing better numbers than before the project. A couple of milestones slipped by a week or so, mostly around testing. Happy to recommend them.

Project summary

We partnered with Danubio to add an AI chatbot to our support site that answers questions from our help docs. They also took care of integrations with a couple of third-party tools we already used. The project took roughly 3 months from kickoff to launch.

Professional team that made a complex project feel manageable

Harsh Reddy / Operations Manager | May 08, 2026

We were very happy with how this project went. 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.

A reliable long-term partner for our tech needs

Rachel Patel / Managing Director | Mar 03, 2026

The project went well overall. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

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. If you need a team that communicates well and delivers, they are a good choice.
