The phone's next
interface layer.
StareBrain turns plain language into confirmed, on-device action — a text sent, an event booked, a call placed. We're raising a pre-seed to take the MVP from spec to a 20-person beta in 12 weeks.
Every phone already has hundreds of apps on it.
None of them talk to each other, and all of them cost taps.
StareBrain replaces the tapping with one sentence.
One interface, confirmed before it acts, sitting on top of everything else.
Same phone. Different interface.
The wedge
Command interfaces (Rabbit R1, Humane) tried to sell new hardware. StareBrain skips the hardware problem — it's software on the phone people already carry.
The timing
On-device and API LLMs are finally fast and cheap enough to sit in the critical path of a phone action without breaking the UX.
The wedge user
Power users and busy professionals first — the segment that already strings together Shortcuts, Tasker, and third-party automation to save minutes.
Free to prove it works. Paid once it's indispensable.
Free
MVP ships free to build usage data and a beta cohort of ~20 power users.
Freemium
Core commands stay free; multi-step agentic workflows and integrations become the paid tier.
Platform
Third-party app integrations (Canva, CapCut, email) open a distribution channel other apps pay to be inside.
Not an idea on a slide. A build in progress.
MVP defined
5 command categories locked: messaging, calendar, device control, app launch, calls.
Stack chosen
Kotlin + Compose on Android, FastAPI + PostgreSQL backend, Nvidia NIM for reasoning.
Security-first design
Confirm-before-execute on every action, encrypted local history, permission-scoped LLM prompts.
12-week build plan
Backend and Android in parallel, integration weeks 7–10, hardening weeks 11–12.
The ask — pre-seed, currently open
Almost all of it goes into the build.
Engineering
Backend + Android through MVP and integration hardening.
LLM & infra
Nvidia NIM usage, hosting, PostgreSQL, monitoring.
Security review
Third-party audit before public beta.
Beta & GTM
Recruiting and running the first 20-user beta.
Let's talk before the beta fills up.
