A reliable long-term partner for our tech needs

Pieter Dlamini / Co-Founder & CTO | Sep 21, 2026

Stonks did good work for us, and we would use them again. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Even with the time zone difference, responses usually came the same day and we never felt left in the dark.

We launched on schedule and have not had any major issues since. Their team changed one developer midway, which slowed things down for a couple of weeks.

Happy to recommend them.

Project summary

We partnered with Stonks to build a demand forecasting model on top of our sales data. The project was split into milestones, with a working build shared at the end of each one. We worked together for around 2 months.

Stonks Delivered a Quality IoT Development Solution on Time

Jess Shaw / Managing Director | Sep 02, 2026

I would rate this engagement highly on almost every front. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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. If you need a team that communicates well and delivers, they are a good choice.

Project summary

We partnered with Stonks to set up a sensor network and alerts for our cold storage facilities. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 6-month engagement.

Dependable Mobile App Development Partner for a Growing Fashion & Apparel Business

Lauren Wallace / Co-Founder & CTO | Aug 31, 2026

Stonks did good work for us, and we would use them again. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. They shared working builds regularly, so we could test early and give feedback before things were locked in. Their project manager kept things organised and was quick to flag anything that might affect the timeline.

The Mobile App Development work has already made a noticeable difference — tasks that used to take hours now take minutes. A couple of milestones slipped by a week or so, mostly around testing.

We are already discussing the next phase with them.

Project summary

We hired Stonks to rebuild our existing mobile app, which had poor reviews and frequent crashes. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 7-month engagement.

Stonks Delivered a Quality Web Development Solution on Time

Jonas Koch / Senior Product Manager | Aug 26, 2026

Stonks did an excellent job for us. 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. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Since launch, everything has been stable and our team has adapted to it quickly. We are already discussing the next phase with them.

Project summary

Stonks was brought in to rebuild a slow, outdated web app and move it to a new framework. Their team handled planning, development and QA, with our product owner signing off each milestone. The project took roughly 6 months from kickoff to launch.

Skilled UI/UX Design Team That Understood Our Business

Siddharth Desai / VP of Engineering | Jul 05, 2026

Our experience with Stonks was really positive from start to finish. 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.

Easy to work with and very transparent on timelines and cost

Julia Weber / Managing Director | Jun 27, 2026

They listened, asked the right questions, and delivered

Jason Sullivan / CEO | Apr 29, 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. 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.

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