The entire start up ecosystem is best set up to support companies that have a low chance of success, but are huge if they work. And i think going for something that is huge if it works, will attract the best people. Ah, it's kind of easy to get the first twe people to join. But then it gets really hard. Why is employee 20 going to join? Why does this matter to the world?Why should someone work on your up versus any of the other things they could do? picking something that matters if you're successful is a great way to do that.
