      Chatbot Solution Review from Daria Hlavcheva

      KeenEthics onboarded Lionwood Software to develop an AI-powered chatbot that could analyze photos of vehicle damage and provide an estimated repair cost for insurance company. The project focused on applying AI to a traditionally manual part of the insurance claims process. The solution needed to interpret car damage from uploaded images, identify relevant damage, and translate the analysis into a cost estimate that could support faster and more consistent claims assessment. Lionwood Software took ownership of the AI development and worked closely with the KeenEthics team to align the solution with the product requirements and insurance use case. Their team demonstrated a strong understanding of both the technical challenges of image-based damage assessment and the business logic behind insurance claims. They were proactive in discussing requirements, clarifying edge cases, and addressing dependencies throughout the development process. The resulting solution helped automate an important part of the vehicle damage assessment workflow, reducing the need for purely manual evaluation and creating a foundation for faster claims processing. Lionwood Software proved to be a reliable technology partner with the expertise to work on AI-driven products where technical implementation needs to be closely aligned with real-world business requirements.

      Mobile App Development Review from Nemanja Sindjelic

      My project idea was to create a non custodial mobile crypto wallet that allows users to manage their assets across multiple blockchains, including Bitcoin, Ethereum, Polygon, and Solana. The wallet app had to provide an intuitive and seamless experience for both beginners and advanced users, ensuring secure transactions and real-time updates. And ND Labs did it great! A white label solution by ND Labs offers a minimalistic UI, multi-network support, and advanced transaction fee optimization while maintaining high security standards with biometric authentication and seed phrase protection.Additionally the wallet well addresses the common challenges in the crypto space: high transaction fees, security risks, and complex user experience. The wallet simplifies crypto asset management and provides automated gas fee calculations, real-time balance updates, and push notifications for transactions.My opinion is that these guys are really professional. I definitely recommend working with ND Labs (Poland) to anyone who is looking for a white label solution for their crypto wallets.

We engaged ND Labs for two complex projects an AI-driven coaching platform and a cryptocurrency platform and they delivered beyond our expectations on both fronts. The teams deep understanding of artificial intelligence and blockchain was evident from the start, and they were able to anticipate and address challenges swiftly. Their timely delivery, responsiveness, and commitment to quality have made our collaboration smooth and highly productive. Were thrilled with the results and look forward to future projects together.
