Today's Investor is Neal Hansch, a partner at Rustic Canyon Partners. 

Neal, who got the entrepreneurial bug early in life, started his first startup when he was in college at Duke.

The company is still running today, but he has since moved to the investor side of the table.

Neal has a wide background, ranging from operating positions at small- to mid-sized companies, to investment banking, corporate development and venture capital.

He loves working with early-stage companies and entrepreneurs, in mobile and digital media.

Neal, who will be a judge at Vator Splash LA May 2011, shares his time between Los Angeles and San Francisco.

What's most frustrating and rewarding about entrepreneurship/innovation?

Endless opportunities, means endless directions and decisions to be made, which only time will tell whether the right ones were made and/or taken.

What's the No. 1 mistake entrepreneurs make?

Blindly following a "build it and they will come" mentality and surrounding yourself with people who are entirely like-minded.

What are the top three lessons you've learned as an entrepreneur?

Pick your co-founders carefully. Validate your market before you invest your blood, sweat and tears building a product and launching a company into it. Listen to customers, but not completely.
