TL;DR: equity and stock option plans only help when they are clear, fair, and legally sound

It also warns you not to copy US startup advice into Europe without checking local law, and not to give away ownership just to avoid hard conversations. The short version: keep the plan simple, explain it in plain language, protect your cap table from dead equity, and treat ownership as one of the most expensive things your company has.
