You have to look at the fundamental raison d'être of the business - what is it doing? What's the nature of the business and what are its prospects for success? What are its prospects to break even and then return the sustained profit?

Basically my point of view on unicorns is that private companies which have sky high valuations, it doesn't really mean anything in the real world until it's marked to market. And there's only two ways things get marked to market in venture capital: Either a company is acquired by another company for cash or marketable security, or it goes public, and then it has reporting requirements and then the market will determine the value.

We're in one of the biggest tech bubbles we've ever had.

Everyone who is inside of an expanding bubble can't imagine another world where the bubble collapses on them. It's unimaginable because they haven't lived through it.

A lot of the philosophies of the businesses are just 'we're interested in getting customers now and if we're losing money with each customer now that's okay because we have this huge hoard of venture capital that we can subsidise the operation with and once we have the required number of tens of millions of customers and we drive our competitors out of business, then we can start to raise prices and become a proper business.'

We live in a global market and money's fungible and hedge fund private equity is looking for momentum plays, and there ain't no momentum plays in bonds, right? When the interest rates were spiking up or down, well they never really spike down they do spike up though. Something's got to happen, there's got to be motion, the dice has to be rolling on the board, and if it's not then they're not going to play because they're not going to get the adrenaline rush from looking at... you know, money markets fund interest rates or bond interests or whatever. It's got to be sexy.

Venture capital has peaked in terms of its appetite, in terms of how much money it wants to put in. So now private equity funds are piling in. Primarily because interest rates are virtually zero so there's no fixed income play and they're not moving around.
