A reliable long-term partner for our tech needs

Jason Coleman / Founder & CEO | Oct 06, 2026

Simplex did an excellent job for us. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

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

We would definitely work with them again.

Project summary

Our company worked with Simplex to build a demand forecasting model on top of our sales data. The work covered requirements, design, development, testing and launch support. Overall it was a 5-month engagement.

Simplex Delivered a Quality UI/UX Design Solution on Time

Maya Tremblay / Co-Founder & CTO | Sep 22, 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. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

We launched on schedule and have not had any major issues since. We are already discussing the next phase with them.

Simplex was brought in to redesign the user experience of our SaaS product. Their team handled planning, development and QA, with our product owner signing off each milestone. We worked together for around 4 months.

Professional UI/UX Design Team, Smooth Delivery From Start to Finish

Owen Sandhu / Head of Digital | Aug 01, 2026

Overall we had a good experience working with Simplex. 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 developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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. Their team changed one developer midway, which slowed things down for a couple of weeks. We would definitely work with them again.
