The thing is, after she got that $200k in branded VC capital from family friend Tim Draper, Holmes went knocking on the doors of all the big silicon valley VC firms and all the big bio-sciences VC firms. They consulted with blood scientist type people who informed them device had zero chance of living up to it's promise. All of them said "Sorry Elizabeth, we must politely decline your invitation to flush our money down the toilet."
The money she did get after that seed funding was from fly-by night wannabe VCs, and the bandwagon effect took off from there. Who did their due diligence? Nobody. I'm not shedding any tears for Rupert Murdoch, but there were hedge fund managers in charge of people's pensions who gave Theranos 100s of millions of dollars without looking into what it was they were spending other people's money on. It baffles me that anyone that stupid can get to be in charge of that much money in the first place.
