We hired Diffco to improve the AI behind SaveIT, which reads receipts and extracts individual line items. We expected them to recommend a stronger AI model, but they looked closely at our data and showed us that was where most of the errors were coming from. That finding helped us focus on the right improvements. They also put a process in place to measure accuracy and test changes against real receipts before release. Alongside the AI work, they addressed security issues—especially important for a product that connects to users’ email and accounting software. We’ve been working with Diffco since April, and they continue to support us. We’ve appreciated their clear communication, practical recommendations, and willingness to explain what actually needed fixing.

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. 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.

We hired Diffco to build a complex, production-grade AI agentic system and scalable backend for our client's fintech platform. The engagement spanned architecture, backend engineering, and applied AI/ML — including the AI agents that drive the platform's core intelligent functionality — all within a finance-grade environment with strong security and data-handling standards. Diffco owned the architecture decisions, implemented scalable backend services, and integrated the AI layer so it performed reliably in production. The project was delivered on schedule and within budget, giving us a solid technical foundation we can confidently keep building on. What stood out most was their deep AI/ML expertise combined with senior backend engineering, and the way the team operated like part of our own — taking ownership, suggesting better solutions, and communicating proactively through regular syncs, in-person meetings, and Slack. Their speed and quality let us move faster than we could have with internal resources alone. The collaboration was excellent and we'd happily work with them again. Highly recommend Diffco for AI and complex backend engineering.

We brought on Diffco to support the integration of multiple postal and shipping systems and assist with backend development for our BOPA logistics platform. From the beginning, their team demonstrated strong technical capabilities, quickly grasped our requirements, and delivered high-quality, scalable solutions that significantly improved our system’s performance and reliability. They communicated clearly throughout the project, stayed on schedule, and worked effectively alongside our internal engineering team. Their flexibility and problem-solving approach helped us accelerate key integrations and reduce time-to-market for important features. Diffco proved to be a dependable and skilled partner, and we were very pleased with both the collaboration and the final results.

We partnered with Diffco on a custom software development project for a data management company. Our goal was to find a software development vendor with extensive experience, excellent communication, well-established processes, and one that operates within our time zone. Diffco met all of these criteria perfectly. The collaboration was smooth and efficient, and we are very pleased with the results. We look forward to working with Diffco again on our next project.
