Theranos was a privately held health technology corporation,[2] initially touted as a breakthrough technology company, but subsequently infamous for its false claims to have devised blood tests that only needed very small amounts of blood. Founded in 2003 by then-19-year-old Elizabeth Holmes,[6] Theranos raised more than US$700 million from venture capitalists and private investors,[7] resulting in a $10 billion valuation at its peak in 2013 and 2014.[8][9] Investors and the media hyped Theranos as a breakthrough in the large blood-testing market, where the U.S. diagnostic-lab industry posts annual sales of over $70 billion. Theranos claimed its technology was revolutionary and that its tests required only about 1/100 to 1/1,000 of the amount of blood that would ordinarily be needed and cost far less than existing tests.
A turning point came in October 2015, when investigative reporter John Carreyrou of The Wall Street Journal questioned the validity of Theranos’ technology. The company faced a string of legal and commercial challenges from medical authorities, investors, the U.S. Securities and Exchange Commission (SEC), Centers for Medicare and Medicaid Services (CMS), state attorneys general, former business partners, patients, and others.[10] By June 2016, it was estimated that Holmes’s personal net worth had dropped from $4.5 billion to virtually nothing.[11] The company was near bankruptcy until it received a $100 million investment from Fortress Investment Group in 2017.[12] In September 2018, the company ceased operations.

I saw the new documentary “The Inventor: Out for Blood in Silicone Valley” It was outstanding. You can probably find it on cable or pay for view.
