Building apps is hard... when you're distracted.

When hiring an app or web development team to build custom software, one variable matters most: are the developers fully dedicated to your success, or are you one client of many? Designli brings together designers, engineers, and business minds into on-demand, dedicated product teams that pour themselves, full-time, into the success of your app or web-app initiative. Existing as your dedicated software engineering department, we'll work together to solve your most pressing business problems with custom software. How it Works, and What We Can Build: --> Designli designs, develops, and launches beautiful apps and web-apps that you'll be proud to own, with a process that makes sense. --> Most importantly, we'll do this with a team that is assigned full-time to your project. --> With a step-by-step process, we'll begin by creating a clickable simulation of the User Interface of your app or website, and a development-ready backlog with each feature defined, estimated, and ready to code. --> Entrepreneurs use this output for fundraising. Business leaders use it for internal buy-in and market validation. --> When you choose to move into Development, our staff will be assigned full-time to you, and this team will be composed of the disciplines you need. --> Left alone, designers will create art projects. Engineers will create science fair gizmos. Business minds will create spreadsheets. Your development team will include all three, singularly focused on your success.
