Startups tend to fall into one of two categories: solving a problem or trying to create a new opportunity. On one end of the extreme is a company like Expensify, which solves a gnarly problem – how to easily process expense reports – that existed long before the startup. On the other end is a company like Twitter, which didn’t solve a problem that people had identified, but instead took advantage of a peculiar technological and social moment to give people an opportunity they didn’t know they wanted, but once exposed to, became essential.
