It's not a 0.5x. It's much lower -- $230 million was the amount raised, not the valuation. It's closer to 0.1-0.2x.
Founders and employees would get nothing out of this (aside from whatever HP is giving them directly as incentive to stick around).
It's a pity that we do not have a version of "Who's holding the bag?"[1] for LP and VC funds, but with all challenges to raise money, it would be interesting to see how many funds are losing money at the moment.
This is the inherent feature from VC funds but still, one thing is raise cheap money and having a "circular" money flowing (from A -> B - (...) -> IPO -> A) but if they do not arrive even in the IPO how this ecosystem will work if a US 5 Year Coupon pays 4.40%?
