That's for transferring, the sale only. And the lack of transparency means we also don't know if "most" is really like that, no matter how standard your CEO said it was.
The three startups you worked for probably share some venture capital firm or related board member that copy and pasted the equity contract
But it didn't mean, necessarily, that condition is so prevalent or that much of a roadblock
Hi, company lawyer here. Sorry if that sounded dismissive. You're completely right that there's a right of first refusal built somewhere into most stock issuances to team members. They vary in who holds the right, the range of transactions that trigger the right, exceptions to the right, and how it operates. Accordingly, we look at the paperwork for each company and each shareholder in order to structure a transaction that works, if possible.
Buyers may be scarce if too many employees are so encumbered though. Is that your concern?
