The arbitrary criteria for deciding what companies to include shows they could have just searched for one (valued at over $1B at 2016-01-01 and not publicly traded) that gives the most favorable result. Why $1B? Why not $10B, $100M, or $1 million? Why 2016? Why not 2015 or any time in the past decade or two? Why not listed companies? Is that so they can call them "startups", or is it because $1B+ listed companies are mostly founded by American born people? I couldn't find any mention of their methodology for selecting criteria in the linked report. Without that, the only conclusion seems to be "water is wet". This doesn't look like science. It looks like politics and is inherent dishonesty.
