Mystic Media has been excellent to work with, offered great value, and their expertise and project management has been evident throughout the development process. We hired Mystic to take an idea and concept drawings through UI/UX and graphic design, programming and development, all the way to the market. They have met or exceeded all milestones, even with significant additions to scope along the way. We're currently in beta testing before release, and we are very satisfied with the entire experience. Mystic has earned my unqualified endorsement for anyone looking to develop their first app with them, as we have done.

The Development Factory Reviews & Testimonials

Tony Greco's Review Sourced from Google
TDF provided us with product management, development, and strategic consultation. We started to build the product with an individual and had initial wireframes and mock-ups, but the project quickly grew larger than an individual person could handle. TDF evaluated what we had and gave us feedback, then created a plan to replace and fix what had already been done. They started with extensive customer development-- something we missed the first time around-- so their new wireframes and plans were based on what our customers actually wanted. Then, they executed the plan.
In addition to the development work, they also took care of logo and design work. They used Amazon Web Services for our platform. We have multiple features such as an API, database, and an administration tool for our own interface. We have a provider tool for facilities to update their data within the database. People can find resources on our web page, web application, and an iOS and Android app. We continue to work with them and have found it more effective and efficient to use them as a virtual outsourced department.

Tom Goddard's Review Sourced from Google
We are a consulting firm that specializes in working with healthcare organizations who are seeking to become accredited, stay accredited, or are working with particular healthcare legal compliance issues that we specialize in. The management of a typical accreditation process is complex for both the applicants and consultants providing them with help, so we wanted technology to help simplify and clarify that process.
The Development Factory developed and designed two important pieces of software for us that have gone through multiple iterations over the years. The most important is an online project management platform that has all of our resources in one place and allows us to have secure communications with our clients and exchange documents and feedback important to the accreditation process. The platform also provides dashboards for our clients that allow clients to track their process and see how they're doing based on our scoring system that scores any documentation that will be sent to accreditation organizations.
The second piece of software TDF built is a training program called AccrediTrain. We had a training software before, but they built a new self-service version that is completely automated, allowing a client to schedule a training for their employees without having to involve any of my staff.
As a result of the work TDF did for our firm, we are now able to handle a larger number of clients with the same number of staff, helping us to increase our revenues by a factor of four.
Beyond that, the reactions to our platforms have been outstanding. Just recently a new client was having her first experience with Goldfinch and she said it was just amazing. Another client of ours is a competitor and asked us for help on a project. This is an organization that has a particularly sophisticated knowledge about the accreditation process, and their CEO and president was very impressed by our software platforms.
They really listened to our description of what we do and how we do it and then turned that into software that quite beautifully captures what we do and how we do it. They clearly care about us and our satisfaction.

I worked at Sileria for an year when it was just an start up and that was one of the best learning experience I ever had. The company has top notch programmers and analyst that can solve any complex business problem. From building enterprise applications, to building 3D games, from building top quality search engine optimized websites to building Internet of Things applications, from top rated mobile apps to robotics, they do it all and they do it with top quality. They have excellent work ethics and a no-compromise policy on quality of the deliverables.

I've worked with Sileria as far back as 1994 - in the very early days of Virtual Reality systems development. They were extremely adept at integrating data glove, trackers and head mounted displays with the VR systems development package. They worked with me on a number of VR projects over the years, along with doing database systems work.

We partnered with &above on a joint client project, where they led design and development while we handled content strategy and SEO. The experience was smooth throughout. Their design work was sharp, their dev execution was clean, and they were easy to work with as a cross-functional partner. Would happily collaborate again and recommend them to any brand looking for a strong creative and technical team.
