Easy to work with and very transparent on timelines and cost

Mitch Taylor / Program Manager | Oct 10, 2026

Our experience with Castelan Interactive Inc 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. 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. Overall, a team we trust and plan to keep working with.

Project summary

Castelan Interactive Inc was brought in to develop a field-staff app with offline mode that syncs back to our main system. The project was split into milestones, with a working build shared at the end of each one. Overall it was a 7-month engagement.

Capable IT Managed Services team — happy with the end result

Harsh Joshi / Co-Founder & CTO | Aug 22, 2026

Overall the project was a success, though it was not without some challenges. 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 IT Managed Services work has already made a noticeable difference — tasks that used to take hours now take minutes. Estimates on a few features were optimistic and those took longer than planned. Happy to recommend them.

Reliable Mobile App Development Partner That Delivered What They Promised

Lukas Richter / VP of Engineering | Jul 04, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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.

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 engaged Castelan Interactive Inc to rebuild our existing mobile app, which had poor reviews and frequent crashes. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 7 months.
