Theranos (/ˈθɛrənoʊs/) was an American privately held health technology corporation. It was initially touted as a breakthrough technology company, with claims of having devised blood tests that required only very small amounts of blood and could be performed very rapidly using small automated devices the company had developed. However, these claims were later proven to be false. Founded in 2003 by 19-year-old Elizabeth Holmes, Theranos raised more than US$700 million from venture capitalists and private investors, resulting in a $10 billion valuation at its peak in 2013 and 2014.
