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

    Top awarded
    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.
