Henry Ford once said that, if he’d asked his customers what they wanted, they’d have asked for a faster horse.
He says: "Early in a startup, product decisions should be hunch driven. Later on, product decisions should be data driven."
I talked to Jack Dorsey of Twitter about quite the same topic when he was in Russia last Feb. And he didn't tell me he asked people a lot before starting. He just built something around idea he had a strong obsession about and everything else is a history.
We failed on the cusp of brilliance because we automated our customers out of their jobs.
