Trusted by top companies

Team AppSierra was incredibly responsive to my needs and had a deep technical understanding of what was required. We tried 3 other performance testing companies before coming across AppSierra. We’ll definitely be using their services again and will extend their scope of work, based on the success of this project.

AppSierra team is the most conscientious, well organized and productive developer group I have ever had the pleasure to work with, and I was in web design and development for 20+ years.

We were brought together by a mutual client on a demanding project where I ended up being a project manager(ish)/tech whisperer in addition to web development, and I worked closely with AppSierra for several months, with almost daily conferences and joint work sessions. I was both very grateful and impressed by the skills, good will and talent brought to table by them.

AppSierra truly has a talent for matching the best developer for a job, an extensive pool of enthusiastic, skilled and creative people to choose from, and the “can-do” attitude and flexibility to quickly adjust to fluid project requirements.

I’ve finally found a web development/marketing company I can recommend wholeheartedly, and with which I look forward to working in the future!

I have been working together with AppSierra on a number of new releases. The AppSierra team has always provided us with prompt response, when it comes to the setup of the team, getting to know the contents of the new release package and reporting on the status. AppSierra had a fast response to our requirements and a professional approach, I would recommend working with AppSierra.

BrandAlley UK Limited has been trusting AppSierra for all its Manual Quality Assurance projects and Automation testing projects on our Magenta website. For the entire 2+ years of engagement and partnership, we have always been satisfied and impressed with the performance, dedication and quality of work shown by the 2 QA’s assigned to our account.

AppSierra really integrated well with our team of expert developers, business analysts and management team. They performed case management testing, regression and smoke testing through the development and deployment pipeline. BrandAlley would always be happy to recommend AppSierra’s services.
