I realize valuation numbers like this make headlines and are a quick way to proxy success (or lack of) for a startup. But private market startup valuations are about as useful as public market stock prices, i.e. not useful without more context and information. Even if numbers are technically accurate no journalist would ever write 'Apple's stock price 3 years ago was around $700 vs closer to $100 today...so the company must be hurting.' I'm surprised startup valuations reporting has continued for so long without more disclaimers or information in the articles about what a number really means. (side note: I'm also surprised movie weekend box office earnings are as big an interest as they seem, so what the heck do I know). If people are going to leak valuation numbers, is it right to publish this # without knowing or asking a bit more what term sheets look like? For those who might know, how hard would it be to get more accurate info tracking the common equity value for startups?
