Greg Isenberg

Greg Isenberg runs Late Checkout and previously advised Reddit and TikTok. The channel carries The Startup Ideas Podcast alongside tutorials, and its stated approach — sharing what he is learning as he learns it, without gatekeeping — is what gives the material its pace.

The current focus is agentic AI as a business surface rather than a productivity tool: running an agent workforce, emerging roles like the marketing engineer, protocols that let agents transact, and the specific open-source repositories worth using. Claude Code features are covered as they ship.

The through-line is the same one his idea generation rests on — spotting where a new capability creates a business before the category has a name. Around 707,000 subscribers.
