At 10 employees the company is still incredibly risky. With this scheme you'll never grow past that size.
What do you think is the ideal breakdown of equity for early employees?
You need flexibility because at any moment some killer candidate might come along that you need to juice the grant for. Just being earlier doesn’t mean they contribute more to the company
No, but being earlier does mean taking on more risk, which is the whole argument founders and seed investors make for their cuts.
