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.

Hivex Reviews & Testimonials

Software Development Review from Margaret N.
It was a pleasure working with Hivex. They quickly grasped the scope of our project and provided highly skilled developers within days. These engineers were efficient and integrated smoothly into our team. They built a robust remote work system that significantly improved our team's collaboration and productivity. The whole process was smooth, and the results were exactly what we needed.

Software Development Review from Olena Shabunina
We needed to quickly expand our dev team to build out a new feature set, and Hivex helped us find and bring on skilled remote developers to make that happen. The devs hit every deadline we set, sometimes even early. If we needed changes or had questions, they were super responsive - usually got back to us within a couple hours.

Software Development Review from Isammara Lourenço
We had a temporary gap in our technical team due to some transitions, and we needed to keep our development momentum going strong. Hivex provided us with skilled developers who seamlessly integrated into our team. They had the expertise we needed and filled the gap until we made permanent hires. Our collaboration with Hivex made sure our projects kept going without delay, we didn't lose our development momentum, and there wasn't any disruption. It was a huge help during a challenging time.

Kyle Neely's Review Sourced from Google
Sketchy method of cold calling to get leads by claiming they talked to someone else at my org that they did not in fact talk to. Called on my personal cell phone. Would not do business with them if the engage this this type of misleading lead generation.
First's Review Sourced from Google
Sketchy people would be a polite way to put it.Kept sending advertisements to a general email box, I responded asking to unsubscribe, they started sending those advertisements to the email from which I responded.I wouldn't trust these people to do anything.
