I'm not very familiar with how raising funds works so this is a genuine naive question and I'd appreciate if someone could explain this to me. On their "About Us" page, they say that they've raised $142M in venture funding. How much equity VCs typically get for such an investment? 20%? In that case, the exit of the VC would be around $240M which in not even a 2x profit. Is it possible that the equity owned by the VCs is much larger than that? It seems to me that VCs would have to own a very large percentage of their equity to make this acquisition worthwhile for them, in which case the original founders wouldn't get anything nearly close to the $1.2B purchase price.
