      UI/UX Design Review from Djamel Bettahar

      We hired Glorium to design the UX/UI for an investment platform we are building. The team conducted research and really dove into what the needs of the users were. They assessed the landscape of the app and focused on key leverage points. I am very happy with the final deliverable. The team was quick to implement feedback and always stayed on top of things. The design came out really beautiful. They really care about us as the client.

      Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

      Mobile App Development Review from Julia Platova

      We partnered with Diffco for a comprehensive software development project aimed at delivering a mobile application and backend system for our client. The goal was to create a seamless, secure, and scalable solution within a 4-month timeline and $50k-$200k budget. Diffcos team was highly professional from start to finish. They handled everything: UI/UX design, backend architecture, API integration, and deployment. After the launch, they continued to support us with maintenance and performance optimization. The application received positive feedback and has proven stable and scalable. Were highly satisfied with Diffcos expertise, commitment, and ability to deliver real results.

      We received very friendly advice. The advice given could potentially save us a lot of money and time. We particularly appreciated that Soxes wasn't primarily focused on sales. However, we've only had one consultation so far, so I can't yet comment on the app development.
