Cory Johnson is the host of the daily Drill Down podcast and the founder of the Business Podcast Network.

Johnson’s peripatetic career has seen him in prominent roles as a technology journalist, broadcaster, hedge fund portfolio manager and investor. But fundamentally he’s an entrepreneur -- helping to start media companies such as the Industry Standard, Slam (the world’s largest basketball magazine) and Vibe. He was CNBC’s first Silicon Valley correspondent and helped create TV, radio and podcasts for Bloomberg. He has also worked as the managing member of Epistrophy Capital, a senior executive at the blockchain startup Ripple, and several others.
