IANAL, but I'm fairly sure that a 5 year non-compete is not enforceable in most part of the United States. That seems a bit much if you ask me, so definitely reach out to a lawyer.
What part of the world are you in?
non competes are only enforceable for equity shareholders in California. Which I will be as a co-founder.
startuplawyer site is great, thanks for the reference!
You are partially correct, it's only enforceable in partnerships and when someone is selling their ownership interest in a company. So if another company buys you, then they can enforce the non-compete with them for a few years. but if you leave or are terminated, I'm not sure that they can stop you from being employed for 5 years. Again, IANAL, but I've had a few of these conversations over the past few months.
