You're right, not all of them will succeed. Most will fail, in a proportion greater than 80% of all funded projects. In the consumer space, this is an even higher number. The thing is, it's impossible to know in advance with certainty which will fail and which will succeed. But the ones that do succeed create an enormous return on all that sweat and money. Investors try to pick winners, but even then it's acknowledged that the majority of even the best portfolio will not make a large return. From the founder's point of view, building something on your own that people genuinely want is an amazing education - even a small amount of success makes a founder far more valuable and goes a long way to expanding their possibilities to try again.
