OTTMaster Delivered a Quality IoT Development Solution on Time

Stephanie Fisher / Engineering Manager | Sep 11, 2026

OTTMaster did good work for us, and we would use them again. They were upfront about what was realistic within our budget, which helped us prioritise the right features. 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. 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 engaged OTTMaster to set up a sensor network and alerts for our cold storage facilities. They also took care of integrations with a couple of third-party tools we already used. The project took roughly 6 months from kickoff to launch.

Would happily work with them again

Chris Henderson / General Manager | Aug 25, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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

We hired OTTMaster to set up a sensor network and alerts for our cold storage facilities. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 4 months.

OTTMaster Delivered a Quality AI & Machine Learning Solution on Time

Amit Nair / Head of Digital | Jun 25, 2026

We were very happy with how this project went. They shared working builds regularly, so we could test early and give feedback before things were locked in. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. 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.

It has made a real difference to how our team works day to day.

Happy to recommend them.

Project summary

We engaged OTTMaster to automate document data extraction that our team was doing by hand. Their team handled planning, development and QA, with our product owner signing off each milestone. The engagement ran for about 2 months.

A reliable long-term partner for our tech needs

Thabo van der Merwe / Founder | May 14, 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. 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 team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

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

Project summary

We hired OTTMaster 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 engagement ran for about 5 months.

Skilled IoT Development Team That Understood Our Business

Our experience with OTTMaster was really positive from start to finish. 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.

Quality work, a little slower than we planned

Jess Ahmed / Founder | Apr 04, 2026

Overall the project was a success, though it was not without some challenges. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

The AI & Machine Learning work has already made a noticeable difference — tasks that used to take hours now take minutes. We had to follow up a few times on smaller bug fixes after launch. I would recommend OTTMaster to anyone looking for a dependable AI & Machine Learning partner.

Project summary

We hired OTTMaster 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. Overall it was a 8-month engagement.
