Many companies don’t get to Series A and very few companies get to Series B. Even if they do get to Series A or B, they won’t be able to raise the amounts you see in the news and have heavy dilution.
Very few founders have double digits percent ownership by Series B and Series C.
Liquidity of $400k or more is a lot and isn’t available for many founders.
All of this after 7 to 10 years of working 80+ hours week, no social life, loosing family, sacrificing health, taking less than $100k/year salary, constant worry of failure, dealing with ups and downs of employees, being a support system of everyone in the company while not being one for their own families, and no guarantee of success. All of this for seeing their dream come true because failure would be worse.
I think the OP should work on his company for more than 4 months and have more than 10 employees for at least a year to truly understand what it is to be a founder.
Also 20% option pool and exercising options up to 10 years are not uncommon.
