After the UI prototype is approved, our development team selects the technical stack and starts building the software. We implement all design decisions and ensure the application is quick, secure, performant, and meets requirements.

After thorough testing, we release the software. Additionally, we provide ongoing support and maintenance to address any issues or updates.

Ryan Wynch

Program Lead

Design Key did an excellent job by turning a concept into a working MVP that I could provide to my users. They know how to make the development process look easy, highlight underground stones, and suggest features and enhancements. Though I had a complex product, it was delivered on time and to spec. Highly recommended.

Lori Barao

Manager of Operations at MMI Direct

Design Key has worked on several development projects for me over the past two years. They are excellent experts with exceptional client service and communication skills. They are able to dig through complex project requirements and produce an end product that exceeds expectations.

Design Key is spectacular, and they do consistently exceptional work. There hasn't been anything they've told me they can't do… And I've asked for a lot over the years! I could not recommend them more highly.
