A reliable long-term partner for our tech needs

Lena Hoffmann / Operations Manager | Oct 06, 2026

Our experience with iSleak 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. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

Feedback from our customers has been very positive so far.

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

Project summary

iSleak was brought in to set up a sensor network and alerts for our cold storage facilities. The work covered requirements, design, development, testing and launch support. The project took roughly 3 months from kickoff to launch.

Good value and a team that genuinely cares about the result

Isla Harris / Senior Engineering Manager | Sep 04, 2026

We were happy with the final result. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. 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.

We launched on schedule and have not had any major issues since. We had to follow up a few times on smaller bug fixes after launch. We would definitely work with them again.

Skilled AI & Machine Learning Team That Understood Our Business

Mitch Martin / Founder | May 13, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

The AI & Machine Learning work has already made a noticeable difference — tasks that used to take hours now take minutes.

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

Project summary

iSleak was brought in to automate document data extraction that our team was doing by hand. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 9 months.

Dependable Mobile App Development Partner for a Growing Food & Beverage Business

Julia Weber / Project Manager | Feb 12, 2026

iSleak did an excellent job for us. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.
