How to Greenlight a
Physical AI Product

4 Dimensions · 3 Filters · Decision Matrix

STEP 01 — FOUR DIMENSIONS

Position across four axes

AI Capability
A1–A10
What's the soft intelligence? Text, vision, voice, multimodal, memory, reasoning, agentic, on-device…
Physical Capability
S18 + CP4
What can the hardware sense? Camera, mic, mmWave, PPG, LiDAR — and where does compute run?
Form Factor
F1–F66
What does it look like? Wearable, standalone device, or embodied robot.
Target User
P1–P30
Who is it for? No clear user = tech demo, no commercial loop.
STEP 02 — THREE FILTERS

Filter through 3 gates

FILTER 01
Tech Timing
AI Model Readiness — the starting gun. T1 Now / T2 Near / T3 Kill.
FILTER 02
Cost Curve
Per-interaction unit economics. Token cost is the critical variable.
FILTER 03
Form Factor Fit
Friction = form × sensor combination. Green / Yellow / Red light.
STEP 03 — DECISION MATRIX
