Delivered on time and stayed involved after launch

Andre Ramirez / VP of Engineering | Jul 08, 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

The Software Development work has already made a noticeable difference — tasks that used to take hours now take minutes. There were some early misunderstandings on requirements that took a few rounds to sort out.

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

Project summary

We engaged Siena Company to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. They worked alongside our in-house team, which mostly handled business requirements and testing. The engagement ran for about 8 months.

Reliable AI & Machine Learning Partner That Delivered What They Promised

Lauren Carter / IT Director | Jul 01, 2026

I would rate this engagement highly on almost every front. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The result looks great and performs well, and our internal team found it easy to take over.

Happy to recommend them.

Professional team that made a complex project feel manageable

Rachel Hughes / Director | Jun 17, 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. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They shared working builds regularly, so we could test early and give feedback before things were locked in.

Since launch, everything has been stable and our team has adapted to it quickly. We are already discussing the next phase with them.

Project summary

Siena Company was brought in to rebuild a slow, outdated web app and move it to a new framework. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 5 months.

I would rate this engagement highly on almost every front.

The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

It has made a real difference to how our team works day to day. We would definitely work with them again.

Capable Mobile App Development team — happy with the end result

Julia Koch / Director of IT | Mar 26, 2026

We got a good result in the end, but the road there had a few bumps. 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. They were upfront about what was realistic within our budget, which helped us prioritise the right features. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. A couple of milestones slipped by a week or so, mostly around testing. Overall, a team we trust and plan to keep working with.

Project summary

We hired Siena Company to develop a field-staff app with offline mode that syncs back to our main system. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 3 months.

Good work overall, with a few bumps along the way

Nikhil Reddy / Founder & CEO | Jan 22, 2026

We got a good result in the end, but the road there had a few bumps. 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. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

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. We are already discussing the next phase with them.
