If you want to get a tech company off the ground, there are no hacks, no shortcuts, and no substitutes for hard work and scrappiness. That was the message, time and time again, at today's second annual Hustle Con event in San Francisco. As you might guess from the name, Hustle Con celebrates the non-technical side of any tech startup — The pluck and grit that can mean the difference between a successful start-up and roadkill.
