Diffco Reviews & Testimonials

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.

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.

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.

We have only positive things to say about their work product and attention to detail. We highly recommend them and will work with them again.

Software Development Review from Robel Yemane
I've been working with Simform for over six months now. The engagement began with bringing our subscription management platform in-house, and we've since expanded the partnership to other projects due to their broad skill set and consistent reliability. They've gone the extra mileeven over weekends and public holidaysto help us move faster when needed. Communication and project management have been excellent, with any issues swiftly addressed. It genuinely felt like Simform was invested in our success. Having worked with similar firms throughout my career, I can confidently say Simform stands out and comes highly recommended.

Frogslayer Reviews & Testimonials
May Halpirn's Review Sourced from Google
Curious about another reviewer who looked older, a job applicant, who didn't have his call returned. Frogslayer slung cliche pablum his way. Apparently they hire Jr. Devs but do they hire over a certain age? Do they know the law? Their Senior Dev is under 30 and was hired from being a student employee. Curious and curiouser. Maybe Frogslayer isn't as woke as they appear. Friend of mine went through the ringer with them was told they'd get feedback either way. Instead they got the standard blow off rejection after devoting way too much time on a company that might not value "employees over a certain age." Heads up Frogslayer. There are laws.
Jared L's Review Sourced from Google
one of the only companies in town actively seeking real beginners/students to become junior level developers using all stacks and not focused on a particular one but most importantly not stuck with legacy tech debt.

These guys are incredible at what they do. They helped me design a custom software that fit all of my companies needs. The time they spend understanding what my goals were was incredible. They also made tons of suggestions to control the cost. Highly recommend this team!
