I don't mean to ask this ironically; how do these companies come up with these numbers during a sale? Jet.com was sold for $3 Billion, but Craftsman Tools was sold for only $900 Million. I don't really know anything about HelloSign, but can someone tell me roughly why they might have come up with the $230M number?
M&A guy here. Generally companies are valued at EBITDA * Multiple. However when it's a strategic acquisition (which this is) then they tend to adjust EBITDA around an investment thesis. For tech companies, this adjustment can be fairly drastic and multiples can get crazy (general market is about 9x right now, but 15x+ for software providers). There are too many theses to enumerate here, but some commons examples cost takeout, customer cross-sell, resource consolidation, etc.
