      Elvera Kaparchuk Co-Founder at SaveIT Receipts

      Mobile App Development Review from Elvera Kaparchuk

      SaveIT is receipt management on autopilot. You connect your email once, and we import your receipts, extract every line item with AI, categorize it, and sync it with QuickBooks. The AI isn't a feature of the product, it is the product. If it reads a receipt wrong, everything downstream is wrong. We brought Diffco in to work on that core. Since April they've worked on our AI models, fixed security problems in the platform, and helped us build a real strategy around where AI belongs and where a conventional solution is the better call. The most important change was measurement: extraction accuracy is now a number we evaluate every change against, instead of something we judge by trying a handful of receipts. They were also honest in a way I didn't expect from an AI firm. When we assumed a problem needed a stronger model, they showed us it was in our data. That saved us time and money. They continue to support the AI side of the product, and they're easy to work with; direct, technically deep, and clear about trade-offs.

      AI Development Review from Ivan Pasichnyk

      We brought Diffco in to deliver the AI and computer vision components for one of our clients, an image generation startup. Because the work sat inside our own client relationship, we needed a partner we could trust to operate at our standard without us managing them day to day - and that is exactly what we got. Diffco owned the technical approach, built the computer vision and AI layer, and delivered the full scope in three months, on schedule. The engineering quality was high, they raised the right questions early instead of late, and they handled the confidentiality the project required without us having to chase it. After delivery they stayed on to support the system, which mattered to us as much as the build itself. When you subcontract a technical project inside your own client relationship, the risk is that the partner makes you look bad. Diffco did the opposite. They've earned our trust and we'd work with them again.

      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.

      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.

      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.

      Steve Molander's Review Sourced from Google

      Oversight of our databases have always been a challenge. Finding the skillset to properly administer the systems is both difficult to find and high priced for a mid-sized organization. We reached out to Emergent to find out more about their virtual dba services. Their services sounded to be exactly what we needed. That was over 4 years ago. Since then we found Emergent to be a key partner in helping us in administration of our databases. Our systems are highly efficient, highly available and we feel secure knowing they are under the oversight of some amazingly skilled engineers.
