The start-up economy has grown exponentially since the start of the millennium supported by unprecedented levels of investment (think flagship funds like the SoftBank Vision Fund) and trends like the private IPO (companies staying private for longer). Private market failures and soaring valuations (e.g. Theranos, Juicero, WeWork) have put the spotlight on a previously smaller part of the financial markets. Private companies now impact everyone making it crucial to focus on multiple methods of valuation.
