Zillow Inc CEO Goes On Epic Twitter Rant About Tech IPOs

Zillow Inc Z isn't know for its penchant for dramatic headlines, but CEO Spencer Rascoff changed that today. In a series of epic tweets, Rascoff told his 23,100 followers just what he thinks about tech IPOs, and the challenges firms face before going public.

At one point, Rascoff even mentions Alibaba Group BABA specifically, and adds a bit of color regarding the e-commerce giant's upcoming IPO.

As Benzinga reported last week, Alibaba valued the transaction at more than $162 billion. That makes it the largest US IPO ever, BBC News estimates.

Without further ado, here's Rascoff's rant in all its glory:

1/ Interesting to think of recent tech IPOs & how investors' questions at #IPO time played out.
— Spencer Rascoff (@spencerrascoff) September 8, 2014

2/ I'm oversimplifying, but usually there are just 1 or 2 questions that #IPO investors debate on a new issue.

3/ The q for $FB IPO was mobile monetization. Investors at #IPO time disagreed on their chances on mobile.
— Spencer Rascoff (@spencerrascoff) September 8, 2014

4/ Clearly $FB “figured out” mobile monetization, and #IPO investors who were long $FB benefited.
