      John Andesilich's Review Sourced from Google

      I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

      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.

      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.

      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.
