Tensions between the United States and Iran continue to escalate following President Donald Trump’s controversial ordering of a deadly strike on Iran’s top general, and allegations that a Ukraine International Airlines flight might have been shot down by an Iranian missile.

Despite increasing tensions between the two nations, there are Iranian-American communities across the country, and they make up a vital part of the US. The Census Bureau estimates that nearly half a million Americans self-identify as having Iranian heritage. The over 27,000 Iranian-Americans living in the San Francisco-Oakland-Hayward metropolitan area are especially crucial to Silicon Valley, where skilled tech workers are in high demand.

Business Insider has assembled a list of major companies helmed or founded by Iranian-Americans.

Many of the business leaders included on this non-exhaustive list fled Iran in the late 1970s and early 1980s following the Iranian Revolution that overthrew a monarchy and implemented an Islamic Republic.

At a luncheon in December 2019, Khosrowshahi said the best piece of advice he ever received was from Herbert Allen of boutique investment bank Allen & Co.: "I bet on people, not companies.
