- Launch amazing brand with tight/negative margins to drive heavy consumer adoption

- Sell brand to megacorp/PE for hundreds of millions or billions.

- Brand gets "optimized for cost" so buyer gets an ROI.

- By the time the public has soured on the brand, the buyout has paid for itself plus profit.

The solution would be to launch these products with high margin built in, but then everybody scoffs at the cost and you die in the womb.

The unicorn solution is that you actually invent a way of producing the high value thing for very cheap, cheaper than everybody else, so you can compete on price while still having top-shelf inputs. But man, that problem is about 5 orders of magnitude more difficult to solve than simply coming up with a product people will like.
