California Software & AI Studio · Est. 20+ years
Mobile and AI software, built for the long haul.
Sinkoff LLC is an independent California software studio. Two decades of shipping production code, now focused on the kind of mobile and AI-powered products that earn their place on the home screen.
Work
Mobile-first products, end-to-end.
02
AI Integration
LLMs, on-device intelligence, and AI-driven features woven into mobile experiences that feel natural, fast, and useful — not bolted on.
03
Product Engineering
Idea to App Store. Architecture, backend, and the connective tissue that makes a product feel inevitable rather than assembled.
Studio
Twenty years in. Still excited about the next build.
An independent California studio working on a few things at a time — our own mobile apps, plus a handful of chosen client engagements.
We’ve shipped production software for over twenty years across consumer, enterprise, and now AI. The technology keeps changing; the craft of making something genuinely useful doesn’t.
