What qualifications (or quantifications) do you use to ensure that your value is more honest than someone else's? At the end of the day, value is determined by someone who is not yourself.

This article for more me is pretty straight forward. It's a well crafted PR play (whether made by commercial means or not is irrelevant), that draws readers to putting more importance on what metrics are used to determine valuation. Something that they can draw from using a service such as Mixpanel. The reality is that you, nor I, can definitely provide one metric that clearly correlates to financial valuation. Every case is different and every case warrants negotiation.

Mixpanel appears to be a great service btw. I hope my tone doesn't dictate otherwise.
