The article alludes to $169.5M raised at a pre-money valuation of $150M. I'm not sure I've ever seen a round like this take over 50%. Who knows what the future of the company will be, but one thing is for sure: it's completely investor-controlled now.
Dilution as usual. The last investors, whom I believe invested at a higher valuation, have had their liquidation reduced. The founder shares are probably highly diluted; I can't imagine the founders owning more than 10% combined.
