even brian chetsky said they're not necessarily going to go public even if they're ready how much ofs it in terms of the pressure you're getting? >> i think along the way different kinds of capital will come in. you have softbank raising $10 billion fund all that makes it easier for early investor to cash n at the same time, later investors come in that could be with the company three to five years. i think that's the new normal we're dealing with today even facebook the first year or two was rocky as a trading company. all the ceos talk to each other and realize that you have companies that started in 2008, 2009, 2010, so the next two years, '19 and '20, will be very interesting. >> this has been happening for years and years and years. bigger, higher quality companies getting public this is not prior era where some velocity and no path to profitability will get you there. you're just seeing companies so much more substance and those early times can be -- no ceo i've ever met has enjoyed -- they love the spotlight of going on the floor and then it just gets miserable for a while. >>
