Great Experience With PieStack on Our Web Development Project

Priya Graham / Managing Director | Sep 26, 2026

We were happy with the final result. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. 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.

It has made a real difference to how our team works day to day. We had to follow up a few times on smaller bug fixes after launch. Happy to recommend them.

Project summary

We hired PieStack to rebuild a slow, outdated web app and move it to a new framework.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. We worked together for around 2 months.

PieStack Delivered a Quality Software Development Solution on Time

Ashley Patel / Founder & CEO | Sep 18, 2026

Our experience with PieStack was really positive from start to finish. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We are already seeing better numbers than before the project.

Skilled DevOps Services Team That Understood Our Business

Olivia Ryan / Product Manager | Aug 18, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Their project manager kept things organised and was quick to flag anything that might affect the timeline. They were upfront about what was realistic within our budget, which helped us prioritise the right features. We dealt with the same core team throughout, so we did not have to keep re-explaining things.

It has made a real difference to how our team works day to day. I would recommend PieStack to anyone looking for a dependable DevOps Services partner.

Project summary

We hired PieStack to improve our release process, which involved a lot of manual steps. 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.

Good value and a team that genuinely cares about the result

Lauren Reed / Product Manager | Feb 11, 2026

PieStack 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. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. 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.

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

Project summary

We hired PieStack to rebuild a slow, outdated web app and move it to a new framework. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 3-month engagement.
