I wonder how analogous this is to “don’t talk to VC associates” advice. Corp dev is interested in buying a company, any company, at a low price but even once corp dev is sold they’ll have to sell the deal to someone who matters. People confuse “this corp dev person is interested” with “this company is interested”.
If you’re not actively looking to sell, _definitely_ don’t bother taking the meeting unless there’s a champion high up who is personally interested.
Come to think of it, recruiters aren’t all that far off this either…
