      AI Development Review from Oleg Sotnikov

      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.

      From my perspective as a former employee: I worked here for almost a year. Colleagues and staffs here are pretty open-minded but employees are highly underpaid. Also in order to get a job here you must have decent technical skills and English language ability. Pros: nice office, friendly staffs that really take care of employees Cons: underpaid salary

      ISBX is a very professional and talented web development company. The overall experience I had with them in the redesign of our website was outstanding. They were extremely creative, provided viable options at all junctures, and delivered on time and on budget. ISBX also provided a very hands-on, and professional team who understood our need for brand engagement and outreach to a new audience with our website refresh. The team also optimized the new site for mobile usage which was very important to us. ISBX successfully executed our complex project efficiently, with excellent communication and attention to detail at every step. I wouldn't hesitate to work with them again.

      I've been a client of ISBX for nearly three years. They are hands down the best development firm I have ever worked with. They are on budget and on time consistently. They are trustworthy, highly communicative, and very versatile. Nothing is in the "too hard box" for them.
