They listened, asked the right questions, and delivered

Anna Becker / Product Manager | Sep 05, 2026

The project went well overall. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

The Software 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.

I would recommend StacK9 Technology to anyone looking for a dependable Software Development partner.

Project summary

Our company worked with StacK9 Technology to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. The work covered requirements, design, development, testing and launch support. The engagement ran for about 8 months.

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. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. They shared working builds regularly, so we could test early and give feedback before things were locked in.

Solid Software Development Work With Clear Communication Throughout

Ethan Gagnon / Founder & CEO | Apr 24, 2026

Our experience with StacK9 Technology was really positive from start to finish. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Their project manager kept things organised and was quick to flag anything that might affect the timeline. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later.

The Software Development work has already made a noticeable difference — tasks that used to take hours now take minutes. We would definitely work with them again.
