Karen Weize writes: Over the past year, Uber built one of the largest and most successful lobbying forces in the country, with a presence in almost every statehouse. It has 250 lobbyists and 29 lobbying firms registered in capitols around the nation, at least a third more than Wal-Mart Stores. That doesn’t count municipal lobbyists. In Portland, the 28th-largest city in the U.S., 10 people would ultimately register to lobby on Uber’s behalf. They’d become a constant force in City Hall. City officials say they’d never seen anything on this scale.

If you’re starting up a business that fits into a large niche, you might well consider joining forces with your allies and competitors to influence City Hall.
