Viktor Sinzig, CEO & Co-Founder at Halfy Hour
I've worked with the GRT Team for about a year now. They've built a web and mobile (iOS & Android) application for our company and the experience has been fantastic. The entire team is dedicated, hard working, and has deep technical knowledge.We have been assigned a project manager who ensures everything is completed on time and on budget -- they are all an absolute pleasure to work with. I look forward to working with them in months to come. I highly recommend their work!
Ron Herman, TeamFound
For an advertising/web business, we required mobile responsive site. We hired GRT to re-structure the front-end, so it responds well to mobile and tablets. They did a great job in that effort, retaining the design, and adjusting to our requirements. Their work included a design phase where we could see how the site would look in mobile. We have a technology director in-house. So we were working quite closely with GRT's developers.
