i think where people are more borderline is if they can raise at a decent seed valuation elsewhere already (eg based on existing revenue or prior reputation/technology being far more established).
It's well understood that YC has some value add. So the fun question is - what is the valuation you can raise at which it does NOT make sense to enter YC?
YC values you at ~2m when they invest (120k divided by 7%, 380k MFN SAFE aside). Lets say you come out of it worth $10-20m on average. Maybe the connections and other stuff gives you value worth $5-10m. so if your business is valued above 15-30m you should consider NOT going into YC.
Is that a good way to think about it? any of these numbers you would change?
