> company that sells services and develops products
Here is my criticism now - not all products and services are equal, yet the costs to develop them (in SV) are. FB/Google/etc.'s high revenues dictate that their products and services constitute a developer that costs $foo - they set the market rates. Talented developers are fungible, but their salaries are not - thus the disconnect.
> How much higher would that number have been had Everpix built out their own infrastructure?
I don't have the answer to that question, and probably very few people do. There are two points to be addressed there - (1) could they save money by building their own? mature companies deal with that question all of the time (2) this is a real life indication of how much a software services money can make on one client by "selling pick axes in a gold rush" - thereby singalling a reinforcement to that sentiment.
