A company raised more than $700 million, had a board full of famous names, and a big pharmacy chain as a partner. Why did nobody check the machine before believing in it? The answer is not "bad luck". A demo was treated as a product, and nobody was allowed to say "it doesn't work yet".

Very high on promises, very fast down once someone checked.

14 things often said about Theranos, checked against SEC, CMS and court records. Tap each row for the reason.
SEC press release 2018-41 (14 Mar 2018): Holmes, Balwani and Theranos "raised more than $700 million from investors" through false statements.
SEC complaint, via STAT and BioCentury. A MedCity piece gives the projection as $108 million; wording varies but the gap is a factor of about a thousand.
CMS letter of 25 Jan 2016: 5 condition-level deficiencies; hematology was "immediate jeopardy".
CMS sanctions notice of 7 July 2016, together with revocation of the Newark lab's CLIA certificate.
Theranos told CMS (May 2016, via WSJ); former lab director Kingshuk Das testified he voided every Edison result from those two years. The scale is disputed: see the figure above (secondary source).
That is a Forbes estimate (2014) based on a funding-round price, meaning what investors were willing to pay for a promise. On dissolution in 2018, shareholders received nothing (CEO Taylor's letter).
The WSJ article of 15 Oct 2015 was the spark. But the binding findings came from bodies with the power to inspect: FDA (2015), CMS (2016), SEC (2018) and the courts (2022).
The FDA cleared only one herpes test, HSV-1 (2 July 2015). The same year the FDA recorded the "nanotainer" collection tube as an uncleared medical device (Form 483).
Sentenced to 135 months (11 years 3 months) on 18 Nov 2022. In March 2026 the court took 1 year off under amended sentencing guidelines for first-time offenders (Bloomberg Law, secondary source). Reported release dates differ, so this article gives none.
Optimism about the future is different from false statements about the present. The SEC found the claims about military contracts, revenue and the analyzer's capabilities false; juries convicted Holmes on 4 counts of defrauding investors and Balwani on 12. There is no "bad luck" in the record.
SEC complaint: its own analyzer ran only about 12 of more than 200 tests on the menu. Most ran on other makers' commercial analyzers.
The jury acquitted Holmes on the 4 patient-related counts (3 Jan 2022). She was convicted on 4 investor-related counts. Balwani, however, was convicted on the patient counts too.
The lab's own quality-control records logged the failures (CMS-2567: 29% of Edison QC checks failed in Oct 2014). Employees reported to the New York State health department and CMS (testimony, secondary source).
Holmes admitted at trial (Nov 2021) that she added the Pfizer and Schering-Plough logos to reports sent to Walgreens and investors; she said "I wish I had done it differently" (as reported by the press, secondary source).

Scores are Mark's assessment based on the sources in Part 8, not data from a study.
Not bad luck. A demo was sold as a product, and the people who knew the truth had no way to say "it doesn't work yet".
Every startup sells the future. The difference is the tense. "We will run 200 tests" is a risky promise. "Our machine runs 200 tests" describes the present, and can be checked.
Theranos fell over sentences in the present tense: the machine works, the military uses it, the revenue is there. The lesson for ordinary work: when you report, separate "done", "in testing" and "planned". When you hear a report, ask which tense it is in.
Source for "More": the claims come from the complaint SEC v. Holmes (14 Mar 2018); the rest is Mark's commentary.
Works for any demo: software, AI models, prototypes, a colleague's or vendor's "it's done" report.
