Professional team that made a complex project feel manageable

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

We are already seeing better numbers than before the project. We would definitely work with them again.

Stonebridge Logistics is a Logistics & Supply Chain business in Dublin, Ireland. As Managing Director, I was responsible for this project on our side and the main contact for 300DEVS.

What specific problem or business challenge led you to hire this company?

Our existing setup was holding us back. We wanted to build firmware and a companion app for a smart device we were launching before our busy season.

What services did the company provide for your project?

End-to-end IoT Development — from requirements and design through to deployment and a support period afterwards.

Why did you choose this company over other providers you considered?

We compared three or four agencies. 300DEVS asked the best questions and had good reviews from past clients.

How clearly did the company understand your requirements and business goals?

Better than we expected. They pointed out a few things we had not thought about.

How was your overall experience with their communication and project management?

Very responsive. We usually heard back the same day, even with the time difference.

Did the company deliver the project on time and within your expected budget?

It was delivered on time, and the final invoice matched the original estimate.

What tangible results or business impact have you seen since the project was completed?

Our team saves several hours a week, and we have had very few issues since launch.

The consistency. Same team, same standard, from the first week to the last.

Would you recommend this company to others, and would you work with them again?

Yes. They are a reliable IoT Development partner.

Exceeded our expectations on quality and communication

Chris Henderson / Engineering Manager | May 13, 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. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

The Mobile App 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.

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

Project summary

Our company worked with 300DEVS to build iOS and Android apps for our customers, including booking, payments and push notifications. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 7 months.

Why did you choose this company over other providers you considered?

How clearly did the company understand your requirements and business goals?

Good results, communication improved as the project went on

Ben Clarke / Founder | Apr 28, 2026

The final product works well for us, although the process could have been smoother. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

The IoT 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 300DEVS to set up a sensor network and alerts for our cold storage facilities. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 2 months.

Easy to work with and very transparent on timelines and cost

Mark Bennett / CEO | Apr 26, 2026

Overall we had a good experience working with 300DEVS. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. They shared working builds regularly, so we could test early and give feedback before things were locked in. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

Feedback from our customers has been very positive so far. A couple of milestones slipped by a week or so, mostly around testing. We are already discussing the next phase with them.

Project summary

We hired 300DEVS to rebuild our existing mobile app, which had poor reviews and frequent crashes. Their team handled planning, development and QA, with our product owner signing off each milestone. The engagement ran for about 4 months.

Honest advice and solid execution

Harsh Shah / Co-Founder & CTO | Mar 09, 2026

I would rate this engagement highly on almost every front. They shared working builds regularly, so we could test early and give feedback before things were locked in. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.

The result looks great and performs well, and our internal team found it easy to take over. I would recommend 300DEVS to anyone looking for a dependable IoT Development partner.

Project summary

300DEVS was brought in to connect our equipment to a cloud dashboard so we could monitor it remotely. The work covered requirements, design, development, testing and launch support. The project took roughly 5 months from kickoff to launch.
