      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 Lori Feld Oakley

      Our Services organization is scaling quickly and we urgently needed a custom software application to automate our workflows, without breaking our annual budget. CodeStringers was the perfect fit, supporting us from ideation through go-live and everything in between. They innovated, hit their deadlines and released an amazingly high quality application that decreases our internal costs and improves our reputation with our customers. It would not have happened without CodeStringers.

      Enterprise Review from Christian Schraga

      CodeStringers is the perfect outsourcer to call If you have a solid software business idea but don’t know exactly how to bring it to life. They have both a top-notch development team as well as an executive staff with expertise in marketing, finance, and general business acumen. So they can not only build a product for you but they can make sure that the product you want to build is likely to succeed in the marketplace.

      The dashboard Perimattic delivered is minimal, well-structured, and very user-friendly. Small touches like the layout, flow, and clarity of controls make a big difference. Great work by Gaurav and his team.

      Cyber Protect, and its owner Cheyenne Harden, is a wonderful company to work with. Not only is Cheyenne Harden extremely knowledgeable in information, technology, and cybersecurity, but he is also is kind and easy to work with. Him and his company will do everything they can to ensure that your data is secure, protected, and that your technology is running properly. I highly recommend him and his company.

      Cindy L's Review Sourced from Google

      Terrible service. I trusted Cyber Protect LLC to help secure my data, but I still got hacked while under their protection. When I reached out for help, their support was slow, unresponsive, and offered no real solution. They took no accountability and left me to deal with the damage on my own. Completely unreliable and not worth the money. Would never recommend.Edit: Your response is disappointing and frankly evasive. If you have no record of me as a client, maybe that explains why your “protection” failed so miserably. Your slow, unresponsive support and complete lack of accountability left me to deal with the consequences alone. Claiming that neither you nor your clients have ever experienced a breach sounds more like a PR line than reality.If you want to prove otherwise, then start by owning up to your failures instead of brushing off legitimate concerns. Until then, your “enterprise-grade solutions” are nothing but empty words.

      Joshua Scott's Review Sourced from Google

      JDE is the absolute worst construction accounting software I have ever used. My company implemented it over 4 years ago and to this day I still struggle with the interface and I am very computer-savvy. As a PM I have literally considered switching companies to get away from this software. It takes over 15 clicks and multiple inputs to produce a cost report. Their interface is very cumbersome and is barely a step above DOS. Do yourself a favor and stay away from JDE.
