We kick off our investor series (and bid adieu to our app sec series) with Ping Li of Accel. Ping was recently named the #2 investor in the Silicon Valley and is one of the most prominent investors in the security industry. He is remarkable not only for the success of his many investments, but for his candor and approachability. In a wide-ranging interview, we cover the biggest mistakes security companies make, how to successfully pitch your company to a veteran investor like Ping and we play an inaugural game of buzzword bingo to see if there's truly a market for that AI-powered blockchain idea you've been kicking around.
