5(16 reviews)Build software people actually pay for.
Top awardedDesignli helps non-technical founders turn software into real, revenue-generating businesses. Most agencies hand over code and walk away, leaving you to build the business yourself . We work differently, measuring our success by your traction - real users on a live product and real signs that the business is growing. Every engagement is built around a guaranteed outcome : For founders starting from scratch , our TractionLab program puts a real user on a working MVP within 30 days, or your next month is free. From there, the whole team works to turn that first user into many, and early usage into real revenue. For founders who already have something live , we start with a free one-week Impact Week that pinpoints exactly what's holding your product back. You walk away with a customized plan and a guaranteed Day-30 outcome that clears those roadblocks, so you can get back to chasing traction and your vision instead of fighting your product. The burden is on us to prove we're the right partner. Picking a software development agency is one of the most important decisions you'll make as a founder, and we don't think that risk should fall entirely on you. That's why your first 14 days are fully refundable, and you can cancel any time with 30 days' notice. We work using Hypothesis-Driven Development . Building software is cheaper than ever with AI-empowered engineers; the hard part is knowing what to build and whether it worked. So every change we make carries a business metric and a clear bet about what it should move, and we measure whether it actually did. The result is a real feedback loop on whether your product is getting better each week and driving more usage and revenue. Each engagement is staffed with a small, senior pod that gives your product full-time focus and founder-level care , and is paid on outcomes, not promises.6 works in Software DevelopmentLocated in Greenville, United States (+2)From €10,000 for Software DevelopmentWorked in Banking & Financials (+9)Speaks English51-200 membersVIRAL EDGE GLOBAL

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 Software DevelopmentLocated in Fort Bend County, United StatesFrom €10,000 for Software DevelopmentWorked in Marketing & AdvertisingSpeaks English51-200 membersAppCrops
