      Web Development Review from AJ Canty

      We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

      We needed a new website for our business and we knew it was time to update the design and make it more user friendly. Rootstrap helped us create our site with all of the latest technology and they were very flexible in terms of our requests. Award winning work! Kudos.

      Web Development Review from Ori Goldman

      When I was looking to build my MVP I spoke to about 10 shops. Little did I know that I would still be working with that same company over 5 years later. Rootstrap built our MVP and we have stuck with them ever since. Through multiple pivots, design changes, thousands of implemented features, we still feel lucky that we found them 5 years ago.

      HTML5 Review from Pete Ghiorse

      Rootstrap is the real deal. We've worked with them on our app from day one. From the first napkin sketch through V2 of our app, Rootstrap has been one of the most reliable value-producing companies I've ever worked with.

      Jennifer Sorcher's Review Sourced from Google

      I have had such an amazing experience while working with Clap Creative! DK has been helping us for a while now, and he has built our site so beautifully! Not only is he quick to answer and eager to get the job done, but he is also informative and respectful as well! You can tell that DK and his team know what they're doing, and I would recommend them to anyone and everyone! Whenever we have a small site glitch or SEO issue, they fix it within the hour! A very much needed quality in any web team! To sum it up, Clap Creative is one of the best web teams I have ever worked with!
