Going to 4% makes YC much more attractive. At 7% it's really hard to justify, though even at 4% for such a small investment it may be a hard pill to swallow for founders who aren't right out of college.
I know talking to pre-seed and seed investors that they expect you to have enough data to be able to quantify whether people really love your product.
At that point you basically have customers and traction and so $150k for 7% looks like a major negative than a positive.
Would you say such companies are worth more the $2M on average?
