Can someone who lives in a third world country target an investment round from a VC in US? From the likes of Ycombinator, etc?
Funding Equity Venture Capital
See the answer to http://www.brightjourney.com/q/incorporating-startup-another-country-tax-benefits-negatively-affect-able-raise-money-vcs#a-53203 :
"Actually getting funding is a very tricky and subtle dance with investors. Once they are interested, you will discover that any delay greatly increases the risk of the deal being cancelled. For very good reason, VCs never invest in companies incorporated abroad. So you'll have to do a corporate flip at the last minute, which is likely to be complicated and, in the end, will kill the deal"
