Web Development Review from Raj Sardana
After working with Webisoft for a few months, I'm really pleased with the caliber of support and output I've had. I manage a little business, so I'm highly involved. I am aware that I have managed previous marketing companies a little too poorly in the past. However, Webisoft has shown me a great deal of patience and has taken the time to comprehend my unique demands and create a plan to address them.
Trevor Ogata CEO at TIX

Blockchain Review from Trevor Ogata
Our team hired Webisoft to build out our alpha version of our to ticketing platform. Webisoft did an incredible job providing excellent customer service, reliability, communication, and adaptability. Webisoft was recommended by colleagues in the industry and did an incredible job given the difficult time constraints they had to work within. They were a great partner and we hope to work with them more in the future. (Verified via email)
Pixel Guru, a mobile solution, helps dealerships have more online car sales by increasing inventory turnover. It hired Webisoft to develop its iOS & Android applications and the management system. The project was executed using React Native and Django. Webisoft's approach was marked by flexibility, professionalism, and punctuality. The agency's project management style was excellent, equipping Pixel Guru with essential tools and feedback for seamless tracking. (Verified by email)

Leanware Reviews & Testimonials
Julia Antoci CEO at GloFlow
5.0★
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.

We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs.

Ok, we had year lasting project and I’d like to admit the confidence and stress resistance of the team, in each situation they didn’t panic but started searching the reason of the error, and finally eliminated it.Besides, among all, team has strong work ethics and sets an example with his perfect attendance. Of course, the attendance of this team members also contributes to the productivity levels and the project results. Yes, that was that impressed me most… I can say it for sure having in past bad experience with the Indian programmers)))
