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.

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.

Web Design Review from Patrice Archer

They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.
