Diffco Reviews & Testimonials
Ivan Pasichnyk CEO at WeLabelData
5.0★
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.

Software Development Review from Daria Stolyar
We hired Altoros engineers as an essential extension of our client-facing internal teams. This was a tough decision because our reputation as a brand depends on the overall efficiency of our processes and we needed to make sure all risks are mitigated when it comes to delivery. Altoros has not let us down.Together with Altorosians we successfully deployed a number of tough and technologically complex projects on time. So our collaboration is certainly set to continue.

Ruby on Rails Review from Greg Lipper
In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.

App Maestros Reviews & Testimonials
David B Review from Google
1.0★
David B's Review Sourced from Google
I want to share my experience so others are aware of the tactics this company uses. I was first contacted via an unsolicited spam text message promoting app development services. I had never heard of this business before, nor did I request any information from them. To see who was really behind the spam, I replied with a simple question about app pricing. The next day, I was contacted directly by this company.What was most concerning is that they tried to claim I had emailed them asking for their services — which is completely false. I never sent them an email or initiated any legitimate contact. The only reason they had my information was because of their own spam outreach. This is both misleading and dishonest.Professional companies do not need to resort to spamming strangers or fabricating stories about how potential clients found them. This type of behavior demonstrates a serious lack of transparency and integrity. If a business cannot be upfront and honest during the very first interaction, it raises major red flags about how they would handle a client’s project, communication, data, and money over time.Based on my experience, I cannot recommend this company. Trust is one of the most important parts of choosing a development partner, and unfortunately, their conduct showed me they are not worthy of that trust. I strongly advise anyone considering working with them to be cautious and look elsewhere for reputable professionals.
