Foreign-born founders have started 44 of the 87 start-ups with market value of over $1 billion, based on a study from the National Foundation for American Policy and cited in the Wall Street Journal. These start-ups have created tens of thousands of jobs, not counting the almost 200,000 Uber drivers (Canadian-born founder). The Marimekko chart below shows the 44 companies grouped by country-of-origin of founder and sized by market value. It shows that Canadian, European, Indian and Israeli-born founders were the largest creators of market value.
You can summarize a great deal of information in a Marimekko chart. The chart brings home the value of these immigrant founded companies to the economy much more than a table listing each one and its value. You can see both the relative importance of different countries and regions and how a few large companies skew the total market value of the group. The 44 companies are about the limit for a Marimekko chart that can be shown on a single page PowerPoint slide. Some of the smaller companies are shown in 8 point font. With more companies, you might want to group the smaller ones in an "Other" category. Here is the chart in SlideShare to download and edit using Mekko Graphics:
