A reliable long-term partner for our tech needs

Eric Reed / CEO | Sep 20, 2026

Our experience with Stiff Upper Lip LLC was really positive from start to finish. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We launched on schedule and have not had any major issues since. We are already discussing the next phase with them.

Project summary

Stiff Upper Lip LLC was brought in to redesign and rebuild our company website on a modern stack. The work covered requirements, design, development, testing and launch support. Overall it was a 7-month engagement.

Easy to work with and very transparent on timelines and cost

Julie Roy / Founder & CEO | Sep 20, 2026

We were happy with the final result. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

It has made a real difference to how our team works day to day. Their team changed one developer midway, which slowed things down for a couple of weeks. We would definitely work with them again.

Project summary

We partnered with Stiff Upper Lip LLC to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. The project was split into milestones, with a working build shared at the end of each one. The engagement ran for about 7 months.
