So I just read this HN posted article (The 7 Habits of Highly Overrated People - https://news.ycombinator.com/item?id=6965295) and thought a lot about my co-founder who is doing jack shit in the company. I already talked to him about lowering his share options (which he currently holds about 40%, (same as me, after seed round dilution)), but with no avail. He actually threatens the company's success if I ever try to "sneak a move" on him when in reality his contributions are near 0 for product development as well as S&M.If I talk with my boards on his misbehaviour it will get them stressed and stop believing on the company. Is there really no way to fire him and the only way is to actually quit ?
