Ask HN: Non-solicitation agreements/cofounders

How are non-solicitation agreements typically viewed for colleague leaving to start a business together? For instance an engineer and product manager decide to leave a company that they’re both working for to create a startup in a non-competing space. Are they opening themselves up to liability for “soliciting” each other to leave their current job? Disclaimer: not looking for legal advice, and if I actually needed it I would find an employment lawyer. I’m merely curious and my searches are coming up empty and tend to only focus on the customers/sales aspect on non-solicitation.
