Theranos was valued at $9B. In this video the SEC sits Elizabeth Holmes in front of a camera and asks how many tests her machine could actually run. She doesn't know. Probably tens of them, she says, which she agrees means fewer than 100, and she can't name anyone who would know. A lawyer asks whether those tests were validated. They were validated by what the company understood validation to mean back then, she says, and that understanding changed later. Asked who read the guidance document they validated against, she names whoever ran assay development. Asked who that was, she doesn't know. The machine gets three names in one answer: the mini lab, the 4 series, and the Edison. Walgreens supplied the first one during due diligence. By then Walgreens had it running in 40 Arizona drugstores, where ordinary people walked in and had blood drawn. Theranos later admitted more than 1 in 10 results given to Arizona customers were voided or corrected, and paid $4.65M back to about 76,000 of them. Across these sessions she says some version of "I don't know" more than 600 times. She was the one person paid to know.
