Delivered on time and stayed involved after launch

Conor O'Connor / Product Manager | Oct 16, 2026

We were very happy with how this project went. 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. They shared working builds regularly, so we could test early and give feedback before things were locked in.

The result looks great and performs well, and our internal team found it easy to take over.

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

Project summary

Gemstone was brought in to build dashboards that pull our sales, marketing and finance data into one place. They also took care of integrations with a couple of third-party tools we already used. The engagement ran for about 9 months.

Easy to work with and very transparent on timelines and cost

Emma Sandhu / Chief Digital Officer | Aug 16, 2026

Overall we had a good experience working with Gemstone. We dealt with the same core team throughout, so we did not have to keep re-explaining things. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

The UI/UX Design 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.

Project summary

Our company worked with Gemstone to redesign the user experience of our SaaS product. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 6 months from kickoff to launch.

Great Experience With Gemstone on Our Web Development Project

Thabo van der Merwe / Co-Founder & CTO | Jul 25, 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. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We launched on schedule and have not had any major issues since. We would definitely work with them again.

Project summary

Our company worked with Gemstone 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 7 months.
