Good value and a team that genuinely cares about the result

Amit Reddy / Director | Oct 11, 2026

Our experience with OTO DEV was really positive from start to finish. They were upfront about what was realistic within our budget, which helped us prioritise the right features. 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.

I would recommend OTO DEV to anyone looking for a dependable IoT Development partner.

Project summary

We engaged OTO DEV to connect our equipment to a cloud dashboard so we could monitor it remotely. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 4 months.

Julia Weber / Director of Technology | Sep 15, 2026

Exceeded our expectations on quality and communication

Eric Graham / Director of Technology | Aug 28, 2026

We were very happy with how this project went. 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 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. Happy to recommend them.

They listened, asked the right questions, and delivered

Lucy Lloyd / Co-Founder & CTO | Jul 16, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

It has made a real difference to how our team works day to day. We are already discussing the next phase with them.

Easy to work with and very transparent on timelines and cost

Matt Chen / CEO | Apr 20, 2026

The project went well overall. They shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Feedback from our customers has been very positive so far. 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.

Professional IT Managed Services Team, Smooth Delivery From Start to Finish

Priya Miller / Product Manager | Feb 08, 2026

OTO DEV did good work for us, and we would use them again. Their project manager kept things organised and was quick to flag anything that might affect the timeline. 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. Estimates on a few features were optimistic and those took longer than planned. If you need a team that communicates well and delivers, they are a good choice.

Capable IT Managed Services team — happy with the end result

Maya Wilson / Managing Director | Jan 29, 2026

We got a good result in the end, but the road there had a few bumps. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

It has made a real difference to how our team works day to day. 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 hired OTO DEV to take over day-to-day IT support for our offices. Their team handled planning, development and QA, with our product owner signing off each milestone. Overall it was a 5-month engagement.
