What's your point? Blue Apron, Cloudera and Twilio have gone public already... Financials are secret until filing for an IPO and at any given point there are not many companies (tech or otherwise) who have filed, but not yet listed. We don't know who's profitable or who will go public, so the best we can go off of is past history.
Going public is not success if you’re hemorrhaging money. You’re just a pyramid scheme with better marketing, not a profitable business worthy of public investment. That’s my point.
