      AI Development Review from Julia Antoci

      Leanware built the mobile MVP of our AI fitness assistant for iOS and Android. It started with discovery workshops that sharpened the product vision and shaped an MVP roadmap prioritizing launch features while leaving room for expansions like avatars and real-time feedback. They developed a conversational AI engine with custom prompt and context engineering tailored to fitness conversations, one that keeps continuity across sessions, remembers user progress and preferences, and keeps health guidance within safety standards. On top of that they implemented photo-based food recognition, smart search that understands fitness intent, personalized recommendations, progress tracking with AI-generated insights and coaching suggestions, and gamified response formats that make AI answers easy to read, plus the scalable backend behind it all. Their consultation saved us an estimated 20 to 30 percent in costs by avoiding unnecessary complexity, and we launched a functional MVP across the app stores in under eight weeks, faster than planned. Project management was exceptional: clear timelines, on-schedule delivery, and proactive communication via Slack, with expert recommendations guiding decisions rather than every choice being pushed back to us. Their technical skill and creativity made the whole thing feel less like hiring a vendor and more like building with a co-founder.

      Software Development Review from Anonymous

      Leanware delivered two significant projects for our e-commerce platform along with a steady stream of smaller fixes and enhancements. They built a new employee management page in our back office so our customers can create accounts, set permissions, and link employees to entities on their own, and when our mobile app's chat functionality needed replicating in the back office, they built a custom chat and messaging React library from scratch, integrated seamlessly with our design system and existing bespoke solution. Along the way they worked comfortably across Next.js, React, React Native, Apollo, GraphQL, and Hasura, and adapted to our implicit conventions. We ran week-long SCRUM sprints with check-ins three times a week, and they consistently hit the sprint goals on time; even when we needed hard pivots mid-sprint, they adapted without losing pace. As the engagement progressed they increasingly took the lead, asking well-informed questions and offering suggestions on code, product, and design that genuinely enriched the outcomes. What impressed us most was how swiftly they onboarded: given incomplete product descriptions, they asked the right questions to fill the gaps and picked up our undocumented code patterns without getting stuck on minor details. It felt like one cohesive team working toward shared objectives, free of the friction that usually comes with a third party

      Mobile App Development Review from Anonymous

      Leanware has partnered with us since Q4 2023 on two cloud-based mobile apps for iOS and Android, one built in Flutter and one in React Native, handling development on both and the UI/UX design on one. For one project they staffed a team of five mid-level developers, a senior developer, an architect, and a UX designer available as needed. They also took over an app that was unstable and nowhere near production-ready and turned it into a stable, solid product I'm genuinely proud to show. Their processes leave nothing to chance and the code that comes out of them is excellent; they've been flexible and thorough throughout. They meet deadlines, keep their promises, and are careful about what they commit to. The whole team has been great, and Alvaro, their Technical Product Manager, deserves a special mention for being remarkable. I hired them because they were upfront about what they could and couldn't do, and that honesty, together with the tremendous quality of their work, is what separates them from other providers. Both are getting harder to find these days.

      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

FAQs About Software Development Companies in the USA

What services do software development companies in the USA provide?

They typically offer full-cycle software, mobile, and web development, UI/UX design, and cloud and development operations (DevOps) as part of their core services. Some companies also provide AI development and digital transformation services to support a business’s continued growth. 

How much do custom software development services cost in the US?

Custom software development costs in the US start at $90-$160 per hour or $20,000-$500,000 per project, according to data from FullStack Labs. For more complex, enterprise-scale systems, the approximate cost is $500,000 to over $1 million per project.  

The final cost of custom software development services in the US will depend on project scope, complexity, and integration and regulatory requirements. 

What is the typical timeframe for custom software development services?

They can take 8-12 weeks for basic MVP development and over 3 years for production-ready enterprise builds. Estimated custom software solution timelines according to Goji Labs:  

  • Small builds: 8-12 weeks for MVPs and 12-24 weeks for full product release 
  • Mid-sized builds: 8-16 weeks for MVPs and 16-40 weeks for complete products 
  • Large builds: 12-36 weeks for MVPs and 36-144 weeks for fully deployable products 

What processes and performance benchmarks do top US software companies follow to ensure quality software?

To ensure quality solutions, leading software development companies in the USA perform code reviews, automated checks, clear documentation, and reproducible deployment environments. For instance, reputable companies aim for less than 2% defects before production and 99.5% uptime for system maintenance based on data from Shakuro and BlueGrid.io. 

How do I check whether a US software development company can handle a company my size?

Primarily, look for case studies that name the client and the person who signed off. Vague, anonymized case studies hide the exact details you need to judge whether a vendor has handled a business like yours.

A good example of this in practice is Designli, which publishes named stories, including work for a mid-market firm with around $100 million in annual revenue.
