I think Uber or Airbnb will stay and become huge, but they might both be overvalued.
Based on that criteria, Uber & AirBnB should be on top of this list, followed by Palantir and Stripe. Zenefits has not really shown the type of defensible traction that Uber / AirBnB have (right now they are simply a rapidly growing insurance agent with a difficult-to-scale direct sales model). I would not add Spotify to this list - bad margins, and hard to defend against Google / Apple.
Netflix has two major advantages: (1) consumers are far more likely to accept a limited video catalog than they are a limited music catalog, and (2) Netflix has spent a lot of money developing their own content. Could Spotify do the same? Possibly, but probably more difficult to do so.
I think Spotify will in the future generate consistent low profits, much like a utility, and their valuation will likely reflect that.
So agree with you completely.
Blog post opportunity!
I almost suspect someone is in the process of doing so right now.
Would definitely love to see some analysts grade that list in terms of whether the current valuation is sustainable.
For example, if DizruptrCo Inc, sold a 15% equity stake for 200 million, they are a unicorn "valued" at $1.333 billion.
How they come up values for X and Y are part of the VC fundraising black magic. What's being reported here and a lot of other places recently, however, is that VC investors are actually willing to put an abnormally high value on Y in late rounds, because liquidation preferences mean they are very unlikely to lose money. Founders also love this, because it means they get to join the Unicorn Club, hopefully on their way to the Three Comma Club.
This is whats meant by unicorn valuations being "inflated". As always, the people who get screwed the hardest if things go south is the employees. People are starting to figure out, however, that a down round, or really anything short of a spectacular exit, for an inflated unicorn means their options and equity are probably going to end up worthless. This could lead to all the best talent running for the door as fast as they can, death spiral, etc.
Profitability depends on a network of flowing capital. When the input (e.g. of venture funding) dry up, profits will vanish in a shockwave.
That is dramatically true for companies whose business model is to provide services and products for either other companies in the network...
...but also for those catering to their employees.
IMHO a lot of 'problems' which seemed to cry out for an 'app' solution are going to turn out to be first world problems no longer pressing when the economy turns.
Then there's the fact that there are a lot of ugly weather patterns nationally and globally brewing...
Hold on, Toto!
