They must have had a strong position from which to negotiate those favorable terms, in addition to the experience to know to do so, and the integrity to actually do it. The type of people you should follow.
I don't believe they did. This acquisition was by Flipkart, the poster child startup in India, who had a very high bar for hiring. They wanted to interview the non-founders to make sure they met the standard. The founders said you get all or you get none. To be fair, it was a small team of 6-8 employees, so I doubt Flipkart cared. :)
Wait, what are the employee protections like in India that such a deal is enforceable? Why couldn't Flipkart just take them and then fire them a few weeks/months later?
I don't think hiAndrewQuinn was implying that they'd do so, rather, they (appropriately) assume that a for-profit would try to loophole their way out of any obligation, so they wanted to know how exactly the employees were protected.
