Delivered on time and stayed involved after launch

Mark Coleman / Product Manager | Oct 12, 2026

Our experience with Sag system 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. We dealt with the same core team throughout, so we did not have to keep re-explaining things. They were upfront about what was realistic within our budget, which helped us prioritise the right features.

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

Our company worked with Sag system to run performance and load testing ahead of a big launch. Scope included discovery workshops, development in two-week sprints and a short support period after launch. Overall it was a 3-month engagement.

We're a mid-sized Financial Services company based in San Jose, USA. I'm the Product Manager and I oversaw the project from start to finish.

What services did the company provide for your project?

Quality Assurance & Testing, including planning, development, testing and launch support.

How clearly did the company understand your requirements and business goals?

Very well. They asked a lot of questions upfront and turned our rough ideas into a clear plan.

How was your overall experience with their communication and project management?

Very responsive. We usually heard back the same day, even with the time difference.

Their attention to detail and the quality of the final product.

Good value and a team that genuinely cares about the result

Rachel Johnson / Co-Founder & CTO | Aug 12, 2026

The project went well overall. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They shared working builds regularly, so we could test early and give feedback before things were locked in.

Feedback from our customers has been very positive so far. We had to follow up a few times on smaller bug fixes after launch.

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

Easy to work with and very transparent on timelines and cost

Amanda Graham / Founder & CEO | Jul 15, 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. 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.

Since launch, everything has been stable and our team has adapted to it quickly. Estimates on a few features were optimistic and those took longer than planned. We are already discussing the next phase with them.

Project summary

We engaged Sag system to develop and audit smart contracts for a tokenized loyalty program. They also took care of integrations with a couple of third-party tools we already used. We worked together for around 5 months.

Great Experience With Sag system on Our Blockchain Development Project

Faisal Al Zahrani / Director | Apr 23, 2026

The project went well overall. 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 were upfront about what was realistic within our budget, which helped us prioritise the right features.

We launched on schedule and have not had any major issues since. Estimates on a few features were optimistic and those took longer than planned. Overall, a team we trust and plan to keep working with.

Honest advice and solid execution

They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. They shared working builds regularly, so we could test early and give feedback before things were locked in.
