DeDi Collective LLC is a multi-venture company based in Corona, CA — spanning software, hardware, and beyond.
DeDi Collective is a small, independent LLC founded by Matt DeWitt and Yajayra Diaz. We operate across multiple disciplines — beginning with iOS app development and expanding into crafts, fabrication, and sustainable living. Our work is hands-on, thoughtfully built, and designed to last.
DeDi Collective develops native iOS applications for the App Store. Our development practice is led by Matt DeWitt, a Senior Staff iOS Engineer with over 16 years of professional iOS experience dating back to 2010.
Matt has shipped production applications used by millions — including enterprise platforms at ServiceTitan (3.9M+ sessions) and HomeAdvisor (800K monthly active users). He has built and led iOS teams of 20+ engineers, architected large-scale modular codebases, and has deep expertise in Swift, SwiftUI, UIKit, and modern Apple development frameworks.
DeDi Collective brings that same level of craft and engineering rigor to independent app development.
