Our Story

We started Diffco on a simple belief: great software comes from teams who think like product owners and hold a senior bar from day one. From our Silicon Valley base we build AI-native products — agents, copilots, and full systems — for teams in healthcare, fintech, and beyond. Clear communication, product-oriented thinking, and AI-first engineering aren't perks here; they're how we ship.
