Easy to work with and very transparent on timelines and cost

Ravi Fernandes / Co-Founder | Sep 07, 2026

Gun.io did an excellent job for us. 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.

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

We engaged Gun.io to migrate our online store from an older platform to a new one. Their team handled planning, development and QA, with our product owner signing off each milestone. The project took roughly 4 months from kickoff to launch.

Gun.io did an excellent job for us. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

I would rate this engagement highly on almost every front. Their project manager kept things organised and was quick to flag anything that might affect the timeline.
