I am starting a company without enough money to pay a second person a salary, but I need the help. I've found someone who seems great - his previous work is beautiful, he has already done some good work on my project to show that he's serious, and he wants to join the company (part time).
Questions of percentage, vesting stock options, etc, abound. Is there a safe (enough) way to form a company with this man that I barely know?
