It's a John Doerr quote[1]. Here's the opening paragraphs from an article which discusses it:

Legendary venture capitalist John Doerr is said to have once described his investment philosophy as "no conflict, no interest."

In other words, when Doerr and venture capital firm Kleiner Perkins aren't privileged enough to enjoy a potential conflict of interest with respect to a potential investment, they have no interest in making the investment.
