It sounds like there's a disconnect between the questions you're asking and the problem you're experiencing. In fact, there's three separate things you address in your post. 1. When Facebook acquires a startup, how do they get the employees at said startup to keep working at Facebook after acquisition. 2. How does an established company like Facebook keep random developers from leaving for other jobs or to do their own startup. 3. How do I get developers to work at my late-stage startup? Am I offering enough equity?
