      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.

      Web Development Review from Alexander Nikolaevsky

      We have hired the Plavno team to develop a cryptocurrency exchange solution.allow users to make cryptocurrency transactions legally and transparently. Plavno team had to create a solution independent of third-party developers, develop frontend solutions for clients and service administrators, build a full-featured back-end that would include integration with banking and payment systems, and a multifunction module for managing currency exchange transactions, exchange rates.

      Financial Review from Mitya Smusin

      Some problems can only be solved with code, but others require end-user thinking. So Plavno developers remember that the whole goal is to solve problems — not only to write code. They thought about the problem from the restaurantants point of view. They developed a food delivery app with both customer and admim panels, which covers all the necessary functionality.

    • Yana Romanovskaya
      Yana Romanovskaya Product Manager at Beeline
      5.0 ★

      IT Outsourcing Review from Yana Romanovskaya

      Plavno was creating profiles with pulling up a lot of information (clusters). Xunit-based scoring was used when setting up a .NET 2.0 project. Scoring for this format works similarly to Junit. The team extended the products by adding features, fixing bugs. This development can change cluster parameters, cluster management system (current state of the object), customize vectors that lead to this cluster and make predictions.

      Kate Ruscito's Review Sourced from Google

      If I could leave 10 stars, I would! Working with 247Labs on our website was one of the best decisions we made. From day one, their communication was clear, consistent, and easy to follow. We always knew what was happening, what was next, and where input was needed. Their team was responsive, open to feedback, and quick to turn ideas into improvements. They didn’t just execute, they brought smart suggestions that made the final product far better than what we initially envisioned. On the technical and design side, they’re INCREDIBLE. Our site is fast, clean, modern, and built with real attention to detail. Every element was expertly crafted and feels unique to us. What stood out most was how supportive they were throughout the entire process. They were patient, proactive, and genuinely invested in getting the best result for us. Absolutely use 247Labs if you need a website. They deliver, and then they go beyond that!
