Theranos Blood Testing

Theranos Blood Testing is the most egregious overhype in modern tech history, securing the #9 position for its catastrophic failure. Elizabeth Holmes raised $700 million on the promise that a single pinprick could run hundreds of tests, but the technology never worked. A 2015 investigation found that the company conducted only 12 of the 240 projected tests using its own device, relying on modified Siemens machines for the rest. This was 30% slower than the average turnaround time claimed and far more inaccurate than any legitimate lab. The deception unraveled in court, ending with Holmes sentenced to 11 years in prison for fraud—a stark contrast to real biotech successes like 23andMe, which delivered on its simpler DNA analysis. Theranos remains a cautionary tale of how hype can overshadow scientific reality.
