Exceeded our expectations on quality and communication

Sanne de Vries / Founder | Oct 02, 2026

Our experience with Codex Souls 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. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

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

Project summary

We partnered with Codex Souls to build firmware and a companion app for a smart device we were launching. Scope included discovery workshops, development in two-week sprints and a short support period after launch. We worked together for around 4 months.

Professional IoT Development Team, Smooth Delivery From Start to Finish

Arjun Iyer / Director | Sep 12, 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. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

We launched on schedule and have not had any major issues since.

We are already discussing the next phase with them.

Project summary

Quality work, a little slower than we planned

Heather Henderson / Founder & CEO | Aug 27, 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 were upfront about what was realistic within our budget, which helped us prioritise the right features.

The result looks great and performs well, and our internal team found it easy to take over. Documentation at handover was a bit thin and we had to ask for more detail.

Happy to recommend them.

Would happily work with them again

Lukas Fischer / Founder & CEO | Aug 17, 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. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

Since launch, everything has been stable and our team has adapted to it quickly. I would recommend Codex Souls to anyone looking for a dependable IoT Development partner.

Project summary

We hired Codex Souls 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. The engagement ran for about 2 months.

Easy to work with and very transparent on timelines and cost

Heather Brooks / IT Director | Aug 05, 2026

Codex Souls did good work for us, and we would use them again. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. 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 Game Development 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.

Project summary

We partnered with Codex Souls to port our game to new platforms and improve performance. They worked alongside our in-house team, which mostly handled business requirements and testing. The engagement ran for about 2 months.

What services did the company provide for your project?

Why did you choose this company over other providers you considered?
Their pricing was fair and they were honest about timelines instead of just telling us what we wanted to hear.

They understood our goals quickly, partly because they had worked with Insurance clients before.
How was your overall experience with their communication and project management?

Solid delivery, though timelines needed some pushing

Isla Smith / Managing Director | Mar 28, 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.

Feedback from our customers has been very positive so far. Estimates on a few features were optimistic and those took longer than planned. We are already discussing the next phase with them.

Project summary

Codex Souls was brought in to build the multiplayer features for our existing game. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 8 months.
