A reliable long-term partner for our tech needs

Sam Evans / Project Manager | Sep 21, 2026

We were happy with the final result. They were upfront about what was realistic within our budget, which helped us prioritise the right features. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

Since launch, everything has been stable and our team has adapted to it quickly. Their team changed one developer midway, which slowed things down for a couple of weeks. We would definitely work with them again.

Project summary

SISOWL was brought in to redesign the user experience of our SaaS product. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 9 months.

Honest advice and solid execution

Ryan Patel / Co-Founder & CTO | Jul 17, 2026

I would rate this engagement highly on almost every front. 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. 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.

Since launch, everything has been stable and our team has adapted to it quickly. Happy to recommend them.

We partnered with SISOWL to develop a field-staff app with offline mode that syncs back to our main system. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 9-month engagement.

Easy to work with and very transparent on timelines and cost

Rachel Goh / Founder & CEO | Jun 17, 2026

The project went well overall. They were upfront about what was realistic within our budget, which helped us prioritise the right features. 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. 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. A couple of milestones slipped by a week or so, mostly around testing. If you need a team that communicates well and delivers, they are a good choice.

Capable IoT Development team — happy with the end result

Siddharth Kulkarni / Director of Technology | Jun 12, 2026

We got a good result in the end, but the road there had a few bumps. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They shared working builds regularly, so we could test early and give feedback before things were locked in.

We are already seeing better numbers than before the project. Documentation at handover was a bit thin and we had to ask for more detail.

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

Project summary

Our company worked with SISOWL 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. We worked together for around 4 months.

Professional team that made a complex project feel manageable

Pieter Naidoo / Co-Founder | Feb 13, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

The Web Development work has already made a noticeable difference — tasks that used to take hours now take minutes.

If you need a team that communicates well and delivers, they are a good choice.

Project summary

Our company worked with SISOWL to build a customer portal where clients can log in, track orders and download invoices. They worked alongside our in-house team, which mostly handled business requirements and testing. We worked together for around 8 months.

Good work overall, with a few bumps along the way

Layla Qureshi / Chief Digital Officer | Jan 05, 2026

The final product works well for us, although the process could have been smoother. 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 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. We would definitely work with them again.
