We are 3 co founders and we have 33/33/33.

I want to quit it in 2 months and we are currently in the process to raise 500K for 25% before the end of the year.

Is it reasonable for me to keep 10% of it. - They think it's way too much.

Sell to them 10% right now - How much??

Sell 13% of it after the 500k raised - How much??

Thanks!
