Why now
Use this when your product works today but your long-term advantage story is still weak.
Use Case
This is for you if you are building at pre-seed, seed, Series A and need a decision before your next investor conversation. Best moment: Use this after early customer calls and before quarterly roadmap planning.
What you should do
Use this when your product works today but your long-term advantage story is still weak.
Decision: What proprietary signal should we instrument next so our product compounds each quarter?

Weekly loop
Quarterly loop: measure whether product usage improves unique model behavior.
Before
Products where user data cannot be captured for legal or contract reasons.
After
Identifies which workflow events become high-signal training or ranking data.

Do you need large existing data volume?
No.
The key is designing high-quality feedback capture, not starting with a massive dataset.
Is this only relevant for foundation model companies?
No.
Application-layer products often have the strongest opportunity for proprietary outcome signals.
