Polar, founded last year, polls users on smartphones and tablets by letting them choose between two things — for example: Coke versus Pepsi, or Warriors versus Lakers. The startup has served more than half a billion polls in the past eight months and had 1.1 million active voters in September, according to a blog post by founder Luke Wroblewski.
