OPEN FOR 0→1 PARTNERSHIPS
Notes for founders building from 0→1.
Production, AI, and partnership - no agency fluff.
AI Production
Demos compile in an afternoon. Production asks whether anyone can explain, test, and own what shipped. That gap is verification debt — and it is where funded products stall before Tech DD.

Vertical AI
Foundation models are shared infrastructure. Defensible vertical AI lives in workflow fit, proprietary evaluation, and the unglamorous steps between “answer” and “job done.”

Domain Build
The best vertical AI companies begin where operators already feel friction — one loop, one owner, one proof point in production — not with a slide about transformers.
