Stormberry Labs
Privacy-first, client-side apps. Each one shipped as a functioning prototype in a single session: human and sovereign AI agent collaborating in real time. No boilerplate, no server calls, no tracking. The same methodology we deploy for clients who need to ship fast without leaking proprietary data.
