> Ideas with the potential to become big are very much THE scarce resource. They're also almost inherently unknowable. Look back at the history of almost any large, successful SV company. Google was a search company taking on AltaVista. Facebook let Harvard students put up personal pages, taking on MySpace. Amazon sold books, taking on Borders. All of their founders got negative responses at early attempts at VC funding from "experts" who had no idea of what they were looking at, because small companies, by definition, make small products, and usually in markets with some competition by strong incumbents. Would Google have become as big as they did without Gmail, YouTube, Maps, Android? Would Facebook have become as big as they did without Messenger, Events, public pages for businesses and celebrities? Would Amazon have become as big as they did without AWS and Marketplace/FBA? Execution, not the founding idea, is what turns start-ups into giants.
