The 30-Minute Interview Structure That Generates the Most Audience Traction (with Tanh Truong)

Most podcasters chase volume. More episodes, more topics, more talking. Tanh Truong, founder of Proton Capital, grew his commercial real estate show on the opposite bet: fewer formats, more value, and 30-minute interviews that let the guest carry the episode. In this episode of Podcasting Secrets with host Nathan Gwilliam, Tanh reveals why his 30-minute interview episodes earn the most traction while a solo show fades, how he turns each guest into a contact he can call on for years instead of a one-time recording, and how giving eight hours of help before he asked for anything built the relationships and the investor base behind Proton Capital. Would you give eight hours of help to someone before asking for a single thing back?Tanh's answer is the quiet engine under his whole business.
