Marcus J. Calloway
Marcus J. Calloway launched The Signal in 2019 after a decade as a technology correspondent for The Atlantic and a stint as editorial director at a San Francisco digital media startup. What began as a single-mic experiment recorded in a Brooklyn closet has grown into one of the top 50 independent podcasts in the US, with over 2.4 million monthly listeners across 60 countries. His interviews cut through the noise — drawing on 15 years covering Silicon Valley, Washington policy rooms, and the cultural collision between them. He has testified before the Senate Commerce Committee on algorithmic accountability and holds a graduate degree in political economy from the University of Chicago. The Signal is entirely independent — no corporate parent, no venture capital, no editorial compromise.

WHY LISTEN
Guests come alone — no PR handlers, no approved talking points, no damage control on standby. What you hear is what they actually think, not what their publicist cleared at 9am.
90-minute conversations that go where others won't. Ideas need room to breathe — we give them the whole house.
Tech founders, moral philosophers, Olympic athletes, financial whistleblowers — the signal cuts across every field, connecting dots no single-niche show ever could.
No ads dropped mid-sentence. No softballs lobbed to protect relationships. Every minute of every episode earns its place or it gets cut before you ever hear it.
