Sam Altman was an entrepreneur at heart. That’s what makes hims such a great venture capitalist in return. Altman built and sold a moderately successful location-based services company called Loopt. He sold Loopt for over $40 million.

Altman has used these experiences and wealth to now lead Y Combinator to which invests in entrepreneurs. This firm has funded and coached more than 730 start ups since its founding in 2005. Altman’s entrepreneurial mind helps him to work with these new start ups in building them into successful businesses.

This example goes to show just how much opportunity there is for entrepreneurs in various fields. Venture capital being one of them. Oh yeah, let it be known that Altman is only 29. Talk about an opportunity to have an impact at such a young age. He does not take it lightly. His goal is to expand the number of companies they work with by 10 fold in the next 10 years.
