People think to create an AirBnb or Twitter, they have to be really smart. However, you really don't need to be that smart to build a massive company. You need a certain IQ of around 110-120 to understand science or how markets work, but after that it's only a matter of how much you believe in yourself/how bold you allow yourself to be.

Being smarter might actually be harmful as the human brain isn't good at filtering all the impressions that the person feels with a higher IQs. For instance, a high IQ often comes with social anxiety, autism and other mental restrictions that lessen the person's capability.

For IQs above 140, people become more specialized from what I've seen. They might be very useful to solve specific problems such as curing cancer/inventing the theory of relativity, but they have a hard time executing a bigger vision involving hundreds of employees and knowledge across numerous fields as one needs to create a startup.

I believe the sweet spot, where a human being can have the biggest impact on the world is somewhere between 130-140. This is an IQ, where a person can understand pretty much everything, but isn't overwhelmed by all the input it gets.
