Dependable Quality Assurance & Testing Partner for a Growing Healthcare Business

Andre Reed / Head of Digital | Aug 29, 2026

We were very happy with how this project went. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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.

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

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

Project summary

We hired JMB Lab to run performance and load testing ahead of a big launch. The work covered requirements, design, development, testing and launch support. We worked together for around 3 months.

Good results, communication improved as the project went on

Charlotte Ahmed / Marketing Director | Jul 26, 2026

The final product works well for us, although the process could have been smoother. They shared working builds regularly, so we could test early and give feedback before things were locked in. 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. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

It has made a real difference to how our team works day to day. Estimates on a few features were optimistic and those took longer than planned. We are already discussing the next phase with them.

Solid AI & Machine Learning Work With Clear Communication Throughout

Jason Brooks / Co-Founder | Feb 26, 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 took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

We are already seeing better numbers than before the project. Happy to recommend them.

Project summary

We engaged JMB Lab 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. We worked together for around 6 months.
