it's hard to tell if we don't know how you gonna spend the money. $20k can be good for a company, but not enough for another. make a detailed plan about your expected expenses and another one for how and when you gonna get money. then try to raise double that amount.
I wished if I can find something better. I get confused when I use it, especially that it feels like it's stuck in 2001 till now. and I hate the auto-friending thing.
