4.8(8 reviews)App and software development for US startups and enterprises.
Highly recommendedStateside Digitals is a US-based app and software development company. We build custom mobile apps, web applications and enterprise software for startups and enterprises. WHAT WE BUILD Native iOS apps in Swift and native Android apps in Kotlin. Cross-platform apps in Flutter and React Native. Web applications including dashboards, admin panels, customer portals, SaaS interfaces and internal tools. Enterprise software. Startup MVPs. Wearable apps for Apple Watch and Wear OS. App modernization and re-platforming for products that have aged out of support. Ongoing maintenance after launch. App store optimization consulting. ONE TEAM, START TO FINISH Design, development, QA and support are all in-house, working across all 50 states. You are not handed to a subcontractor after the pitch, and you are not re-explaining your product to a new face every few weeks. The people who scope the work are the people who ship it. Source code and repositories stay in your name from day one, and store accounts are set up under yours rather than ours. TWO KINDS OF CLIENTS Founders come to us to get a first version in front of real users without paying for features that can wait. That means arguing about scope early, cutting what does not need to exist yet, and building so version two is not a rewrite. Enterprise teams come to us for integration with systems that already exist, role-based access, the security and regulatory requirements of their industry, documentation, and software that will still be supportable in five years. Those are different conversations and we treat them that way. AFTER LAUNCH Apps do not stay working on their own. Operating systems update, dependencies break, store policies change. We offer maintenance and support on everything we build, so launch is a milestone rather than a handover. If you are scoping a build, we are happy to talk through requirements, trade-offs and what a realistic first version looks like before anyone commits to anything.Looking for work in Interface DesignLocated in Fort Bend County, United StatesFrom €10,000 for Interface DesignWorked in Marketing & AdvertisingSpeaks English51-200 membersBrightery
