Great team to work with — professional, responsive and reliable

Carlos Bennett / Director | Oct 18, 2026

I would rate this engagement highly on almost every front. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They were upfront about what was realistic within our budget, which helped us prioritise the right features. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

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

Project summary

Our company worked with ResultStack to run user research and create new designs for our mobile app. The work covered requirements, design, development, testing and launch support. The engagement ran for about 9 months.

Good results, communication improved as the project went on

Jack Smith / Program Manager | Aug 02, 2026

We got a good result in the end, but the road there had a few bumps. 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.

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.

I would recommend ResultStack to anyone looking for a dependable Software Development partner.

Project summary

Good value and a team that genuinely cares about the result

Sam Thompson / Project Manager | May 25, 2026

Our experience with ResultStack was really positive from start to finish. They shared working builds regularly, so we could test early and give feedback before things were locked in. We dealt with the same core team throughout, so we did not have to keep re-explaining things. The developers were knowledgeable and made a few suggestions that ended up saving us time and money.

The result looks great and performs well, and our internal team found it easy to take over. We are already discussing the next phase with them.

Exceeded our expectations on quality and communication

Ananya Shah / Owner | May 21, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. 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 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 would definitely work with them again.

Project summary

Stephanie Coleman / Senior Product Manager | May 09, 2026
