I remember reading a similar article about Hampton Creek, the food startup.<p>How do VC&#x27;s end up investing in stuff like this? That&#x27;s not meant to be a rhetorical question, I know nothing about investing. I&#x27;m genuinely interested in how very smart people end up giving millions of dollars to fund vapourware.<p>What is the due diligence process? Don&#x27;t VC&#x27;s hire an independent expert in the field to audit the core technology? I guess confidentiality is an issue, but we have NDAs for that, right?
