Designli Reviews & Testimonials

Mobile App Development Review from John Laporte
Designli helped us define the requirements, features, and user experience for an app for our motorcycle organization. They produced technical documentation and a clickable prototype covering navigation, member tools, and safety features. They were responsive, delivered on time every time, and turned our broad concepts into something people could actually click through. The prototype got our stakeholders aligned, earned internal approval, and set us up for engineering, and working out design questions early should save us rework later.

Mobile App Development Review from Brandi Heffner
Designli built our SaaS product from scratch, using AI to speed up development, with AWS and Cloudflare in the stack, and they also handle our hosting and maintenance. We had a working MVP in just 30 days and have kept adding features since. In the first 60 days they went beyond what we expected, largely because they took the time to really learn our business and our market. Coordination through Basecamp and Google Meet has kept everything organized.

Mobile App Development Review from Thomas Simmons
Designli took over app development and marketing for our driving school, with the goal of building a product we could eventually offer to other schools. Within two and a half months, the app was up and running in our own school. Their project management is excellent, and they push back constructively, thinking through what we actually need instead of building every request as-is.
